# The Synthesis ToolKit in C++ (STK)
By Perry R. Cook and Gary P. Scavone, 1995--2017.

The Synthesis ToolKit in C++ can be used in a variety of ways, depending on your particular needs. Some people simply choose the classes they need for a particular project and copy those to their project directory. Others like to compile and link to a library of object files. STK was not designed with one particular style of use in mind.

## Unix systems and MinGW

1. If you downloaded the software from the git repository, first run autoconf,

autoconf

otherwise, if you downloaded the software from the STK source distribution, unpack the tar file,

tar -xzf stk-4.x.x.tar.gz

2. From within the directory containing this file, run configure:

./configure

3. From within each project directory, type `make`.

4. To compile a library of objects, type `make` from within the `src` directory.

Several options can be passed to configure, including:

--disable-realtime = only compile generic non-realtime classes
--enable-debug = enable various debug output
--with-alsa = choose native ALSA API support (default, linux only)
--with-oss = choose native OSS API support (unixes only)
--with-jack = choose native JACK server API support (linux and macintosh OS-X)
--with-core = choose OS-X Core Audio API (macintosh OS-X only)
--with-asio = choose ASIO API support (windows only)
--with-ds = choose DirectSound API support (windows only)
--with-wasapi = choose Windows Audio Session API support (windows only)

It is now possible to specify more than one audio and MIDI API where supported. Note, however, that the ALSA library is required in order to compile the RtMidi class in Linux if the `--with-oss` option is provided (only the OSS audio API will be used, not the OSS MIDI API). Typing `./configure --help` will display all the available options. In addition, it is possible to specify the RAWWAVES and INCLUDE paths to configure as (ex. to set to /home/me/rawwaves and /home/me/include):

./configure RAWWAVE_PATH='$(HOME)/rawwaves/'
./configure INCLUDE_PATH='$(HOME)/include/'

The ending "/" is required for the RAWWAVES path. The default behavior will set a relative path that works for the project files included with the distribution (assuming they are not moved). You can also change the RAWWAVE_PATH dynamically via the static Stk::setRawwavePath() function.

If you wish to use a different compiler than that selected by configure, specify that compiler in the command line (ex. to use CC):

./configure CXX=CC


## Windows

MinGW support is provided in the configure script. In addition, Visual C++ 6.0 project files are included for each of the example STK projects, though these may not work with more recent versions of Visual Studio.

##iOS

You can integrate the STK in iOS projects either by using its iOS static library or Cocoapods. See the [iOS README file](iOS/README-iOS.md) for instructions.

# OVERVIEW

The Synthesis ToolKit in C++ (STK) is a set of open source audio
signal processing and algorithmic synthesis classes written in the C++
programming language. STK was designed to facilitate rapid
development of music synthesis and audio processing software, with an
emphasis on cross-platform functionality, realtime control, ease of
use, and educational example code. The Synthesis ToolKit is extremely
portable (most classes are platform-independent C++ code), and it's
completely user-extensible (all source included, no unusual libraries,
and no hidden drivers). We like to think that this increases the
chances that our programs will still work in another 5-10 years. STK
currently runs with "realtime" support (audio and MIDI) on Linux,
Macintosh OS X, and Windows computer platforms. Generic, non-realtime
support has been tested under NeXTStep, Sun, and other platforms and
should work with any standard C++ compiler.

The only classes of the Synthesis ToolKit that are platform-dependent
concern sockets, threads, mutexes, and real-time audio and MIDI input
and output. The interface for MIDI input and the simple Tcl/Tk
graphical user interfaces (GUIs) provided is the same, so it's easy to
experiment in real time using either the GUIs or MIDI. The Synthesis
ToolKit can generate simultaneous SND (AU), WAV, AIFF, and MAT-file
output soundfile formats (as well as realtime sound output), so you
can view your results using one of a large variety of sound/signal
analysis tools already available (e.g. Snd, Cool Edit, Matlab).

The Synthesis Toolkit is not one particular program. Rather, it is a
set of C++ classes that you can use to create your own programs. A
few example applications are provided to demonstrate some of the ways
to use the classes. If you have specific needs, you will probably
have to either modify the example programs or write a new program
altogether. Further, the example programs don't have a fancy GUI
wrapper. If you feel the need to have a "drag and drop" graphical
patching GUI, you probably don't want to use the ToolKit. Spending
hundreds of hours making platform-dependent graphics code would go
against one of the fundamental design goals of the ToolKit - platform
independence.

For those instances where a simple GUI with sliders and buttons is
helpful, we use Tcl/Tk (http://dev.scriptics.com) which is freely
distributed for all the supported ToolKit platforms. A number of
Tcl/Tk GUI scripts are distributed with the ToolKit release. For
control, the Synthesis Toolkit uses raw MIDI (on supported platforms),
and SKINI (Synthesis ToolKit Instrument Network Interface, a MIDI-like
text message synthesis control format).


# SYSTEM REQUIREMENTS

See the individual README's (eg. README-linux) in the /doc directory
for platform specific information and system requirements. In
general, you will use the configure script to create Makefiles on unix
platforms (and MinGW) or the VC++ workspace files to compile the
example programs. To use the Tcl/Tk GUIs, you will need Tcl/Tk
version 8.0 or higher.


# WHAT'S NEW (AND NOT SO NEW)

Despite being available in one form or another since 1996, we still
consider STK to be alpha software. We attempt to maintain backward
compatability but changes are sometimes made in an effort to improve
the overall design or performance of the software. Please read the
"Release Notes" in the /doc directory to see what has changed since
the last release.

A new StkFrames class has been created to facilitate the handling and
passing of multichannel, vectorized audio data. All STK classes have
been updated to include tick() functions that accept StkFrames
arguments.

The control message handling scheme has been simplified greatly
through the use of the Messager class. It is now possible to have
access to simultaneous piped, socketed, and/or MIDI input control
messages. In most cases, this should eliminate the use of the
Md2Skini program.

Realtime audio input capabilities were added to STK with release 3.0,
though the behavior of such is very hardware dependent. Under Linux
and Macintosh OS-X, audio input and output are possible with very low
latency. Using the Windoze DirectSound API, minimum dependable output
sound latency seems to be around 20 milliseconds or so, while input
sound latency is generally higher. Performance with the ASIO audio
API on Windoze provides much better performance.

As mentioned above, it is possible to record the audio ouput of an STK
program to .snd, .wav, .raw, .aif, and .mat (Matlab MAT-file) output
file types. Though somewhat obsolete, the program Md2Skini can be
used to write SKINI scorefiles from realtime MIDI input. Finally, STK
should compile with non-realtime functionality on any platform with a
generic C++ compiler.

For those who wish to make a library from the core STK classes, the
configure script generates a Makefile in the src directory that will
accomplish that.


# DISCLAIMER

You probably already guessed this, but just to be sure, we don't
guarantee anything works. :-) It's free ... what do you expect? If
you find a bug, please let us know and we'll try to correct it. You
can also make suggestions, but again, no guarantees. Send email to
the mail list.


# LEGAL AND ETHICAL

This software was designed and created to be made publicly available
for free, primarily for academic purposes, so if you use it, pass it
on with this documentation, and for free.

If you make a million dollars with it, it would be nice if you would
share. If you make compositions with it, put us in the program notes.

Some of the concepts are covered by various patents, some known to us
and likely others which are unknown. Many of the ones known to us are
administered by the Stanford Office of Technology and Licensing.

The good news is that large hunks of the techniques used here are
public domain. To avoid subtle legal issues, we'll not state what's
freely useable here, but we'll try to note within the various classes
where certain things are likely to be protected by patents.


# FURTHER READING

specific README's for specific system requirements.


# PERRY'S NOTES FROM THE ORIGINAL DISTRIBUTION

This whole world was created with no particular hardware in mind.
These examples are intended to be tutorial in nature, as a platform
for the continuation of my research, and as a possible starting point
for a software synthesis system. The basic motivation was to create
the necessary unit generators to do the synthesis, processing, and
control that I want to do and teach about. Little thought for
optimization was given and therefore improvements, especially speed
enhancements, should be possible with these classes. It was written
with some basic concepts in mind about how to let compilers optimize.

Your question at this point might be, "But Perry, with CMix, CMusic,
CSound, CShells, CMonkeys, etc. already cluttering the landscape, why
a new set of stupid C functions for music synthesis and processing?"
The answers lie below.

1) I needed to port many of the things I've done into something which is generic enough to port further to different machines.

2) I really plan to document this stuff, so that you don't have to be me to figure out what's going on. (I'll probably be sorry I said this in a couple of years, when even I can't figure out what I was thinking.)

3) The classic difficulties most people have in trying to implement physical models are:

A) They have trouble understanding the papers, and/or in turning the theory into practice.

B) The Physical Model instruments are a pain to get to oscillate, and coming up with stable and meaningful parameter values is required to get the models to work at all.

This set of C++ unit generators and instruments might help to diminish the scores of emails I get asking what to do with those block diagrams I put in my papers.

4) I wanted to try some new stuff with modal synthesis, and implement some classic FM patches as well.

5) I wanted to reimplement, and newly implement more of the intelligent and physical performer models I've talked about in some of my papers. But I wanted to do it in a portable way, and in such a way that I can hook up modules quickly. I also wanted to make these instruments connectable to such player objects, so folks like Brad Garton who really think a lot about the players can connect them to my instruments, a lot about which I think.

6) More rationalizations to follow . . .

The Synthesis ToolKit in C++ (STK)

By Perry R. Cook and Gary P. Scavone, 1995--2017.

Please read the file README and INSTALL for more general STK information.

Realtime audio support for Linux currently includes the Advanced Linux Sound Architecture (ALSA), the JACK low-latency audio server, and/or Open Sound System (OSS version 4.0 and higher only) APIs. That said, the OSS API support has not been tested in several years and is not considered a high priority. One or more APIs are selected during compilation using the __LINUX_ALSA__, __UNIX_JACK__, and/or __LINUX_OSS__ definitions. Because the ALSA library is now integrated into the standard Linux kernel, it is the default audio/MIDI API with STK versions 4.2 and higher.

Realtime MIDI support Linux currently includes the Jack and ALSA sequencer support. Native OSS MIDI support no longer exists in RtMidi. If the __LINUX_OSS__ preprocessor definition is specified, only OSS audio support will be compiled and RtMidi will still be compiled using the ALSA API. For this reason, STK now requires the asound library for realtime support (unless only using the Jack API). Realtime programs must also link with the pthread library.

STK should compile without much trouble under Linux. Since all Linux distributions typically include the GNU makefile utilities, you should be able to use the default Makefiles. Typing "make" in a project directory will initiate the compilation process (after initially running the configure script in the top-level directory).

The Synthesis ToolKit in C++ (STK)

By Perry R. Cook and Gary P. Scavone, 1995--2017.

Please read the file README and INSTALL for more general STK information.

The default realtime support for Macintosh OS X uses the CoreAudio HAL API and is specified during compilation using the __MACOSX_CORE__ preprocessor definition. There is also support for the JACK audio server using the __UNIX_JACK__ preprocessor definition.

It is necessary to install the OS X developer kit (or the command line tools) in order to compile STK. STK was successfully tested on the latest version of OS X.

Tcl/Tk on OS X:

I think that tcl/tk interpreter is now included in the XCode package, since I haven't had to download it for several years now.

It appears that socket support in Tcl/Tk on OS X uses the Nagle algorithm, which produces poor response between changes made in the tcl/tk script and the resulting audio updates. Note that this is only a problem when using a socket connection from a Tcl/Tk script.

The Synthesis ToolKit in C++ (STK)

By Perry R. Cook and Gary P. Scavone, 1995--2017.

Please read the file README for more general STK information.

The configure script supports MinGW. As well, STK is distributed with Visual C++ .NET project and workspace files (though these may no longer work with current versions of Visual Studio). It no longer compiles with Visual C++ 6.0.

With Windows XP/7, piping works as under unix. Simply fire up the script files (ex. StkDemo.bat) by either double-clicking on them or from within a shell.

IMPORTANT VC++ NOTE: When compiling "release" versions of STK programs, link to the release multithreaded library. When compiling "debug" versions, link to the debug multithreaded library. Compiler errors will result otherwise.

The DirectSound, WASAPI and Steinberg ASIO audio APIs are supported for realtime audio input/output. The Visual C++ project files included with this distribution are configured to use all supported APIs. In order to use the ASIO API, it is necessary to use the preprocessor definition __WINDOWS_ASIO__, as well as include most of the files in the /src/include/ directory (i.e. asio.h, asio.cpp, ...). If you have a good quality soundcard and a native ASIO driver (not emulated), you are likely to get much better input/output response using that.

When using the DirectSound API for audio input, latency can be high. If you experience realtime audio "stuttering", you should experiment with different "buffer size" and "number of buffers" values.

Realtime MIDI input/output is supported by RtMidi using the winmm.lib API and requires the __WINDOWS_MM__ preprocessor definition.

Visual C++ workspaces have been created for the various STK projects. Everything has already been configured for you. The intermediate .obj files will be written to either the "Release" or "Debug" directories, but the executable files will be written to the main project directories (where they need to be for proper execution). If you should somehow lose or hose the VC++ workspace file for a project, then you will have to do a LOT of configuring to recreate it ... it's probably easier just to download the distribution again from our WWW sites. Anyway, for your benefit and mine, here is a list of things that need to be added to the various "Project Settings" (this was for VC 6.0 ... things have changed with the newer versions of the VC compiler):

1. Under General: Set "Output files:" to <blank> (this will put the executable in the main project directory.

2. Under C/C++ > Code Generation: Set "Use run-time library:" to Multithreaded (use "debug" versions for the debug configuration).

3. Under Link > General: Add winmm.lib, dsound.lib, and Wsock32.lib to the end of the Object/library modules list.

4. Under C/C++ > Preprocessor: Add "../../include" directory to the "extra include" field.

5. Under C/C++ > Preprocessor: Add "__WINDOWS_DS__", "__WINDOWS_MM__", and "__LITTLE_ENDIAN__ to the definitions field.

6. Add all the necessary files to the project.

Remember that items 1-5 above need to be done for each project and for each configuration. There might be an easy way to make global changes, but I couldn't figure it out.

To use the Tcl/Tk GUIs, you will have to install Tcl/Tk.

This describes the latest (version 1.1) implementation of SKINI.

Synthesis toolKit Instrument Network Interface

for the Synthesis Toolkit in C++ by Perry R. Cook.

*********************************
* Too good to be true? *
* Have control and read it too? *
* A SKINI Haiku. *
*********************************

Profound thanks to Dan trueman, Brad Garton, and
Gary Scavone for input on this revision. Thanks
also to MIDI, the NeXT MusicKit, ZIPI and all
the creators and modifiers of these for good bases
upon/from which to build and depart.

1) MIDI Compatibility

SKINI was designed to be MIDI compatible wherever possible,
and extend MIDI in incremental, then maybe profound ways.

Differences from MIDI, and motivations, include:

Text-based messages are used, with meaningful names
wherever possible. This allows any language or system
capable of formatted printing to generate SKINI.
Similarly, any system capable of reading in a string
and turning delimited fields into strings, floats,
and ints can consume SKINI for control. More importantly,
humans can actually read, and even write if they want,
SKINI files and streams. Use an editor and search/
replace or macros to change a channel or control number.
Load a SKINI score into a spread sheet to apply
transformations to time, control parameters, MIDI
velocities, etc. Put a monkey on a special typewriter
and get your next great work. Life's too short to debug
bit/nybble packed variable length mumble messages. Disk
space gets cheaper, available bandwidth increases, music
takes up so little space and bandwidth compared to video
and grapics. Live a little.

Floating point numbers are used wherever possible.
Note Numbers, Velocities, Controller Values, and
Delta and Absolute Times are all represented and
scanned as ASCII double-precision floats. MIDI byte
values are preserved, so that incoming MIDI bytes
from an interface can be put directly into SKINI
messages. 60.0 or 60 is middle C, 127.0 or 127 is
maximum velocity etc. But, unlike MIDI, 60.5 can
cause a 50cent sharp middle C to be played. As with
MIDI byte values like velocity, use of the integer and
SKINI-added fractional parts is up to the implementor
of the algorithm being controlled by SKINI messages.
But the extra precision is there to be used or ignored.

2) WHY SKINI?

SKINI was designed to be extensable and hackable for a number
of applications: imbedded synthesis in a game or VR simulation,
scoring and mixing tasks, real-time and non-real time applications
which could benefit from controllable sound synthesis,
JAVA controlled synthesis, or eventually maybe JAVA synthesis,
etc. SKINI is not intended to be "the mother of scorefiles,"
but since the entire system is based on text representations
of names, floats, and ints, converters from one scorefile
language to SKINI, or back, should be easily created.

I am basically a bottom-up designer with an awareness of top-
down design ideas, so SKINI above all reflects the needs of my
particular research and creative projects as they have arisen and
developed. SKINI 1.1 represents a profound advance beyond
versions 0.8 and 0.9 (the first versions), future SKINI's might
reflect some changes. Compatibility with prior scorefiles
will be attempted, but there aren't that many scorefiles out
there yet.

3) SKINI MESSAGES

A basic SKINI message is a line of text. There are only three
required fields, the message type (an ASCII name), the time (either
delta or absolute), and the channel number. Don't freak out and
think that this is MIDI channel 0-15 (which is supported), because
the channel number is scanned as a long int. Channels could be socket
numbers, machine IDs, serial numbers, or even unique tags for each
event in a synthesis. Other fields might be used, as specified in the
SKINItbl.h file. This is described in more detail later.

Fields in a SKINI line are delimited by spaces, commas, or
tabs. The SKINI parser only operates on a line at a time,
so a newline means the message is over. Multiple messages are
NOT allowed directly on a single line (by use of the ; for
example in C). This could be supported, but it isn't in
version 1.1.

Message types include standard MIDI types like NoteOn, NoteOff,
ControlChange, etc. MIDI extension message types (messages
which look better than MIDI but actually get turned into
MIDI-like messages) include LipTension, StringDamping, etc.
NonMIDI message types include SetPath (sets a path for file
use later), and OpenReadFile (for streaming, mixing, and applying
effects to soundfiles along with synthesis, for example).
Other non-MIDI message types include Trilling, HammerOn, etc. (these
translate to gestures, behaviors, and contexts for use by
intellegent players and instruments using SKINI). Where possible
I will still use these as MIDI extension messages, so foot
switches, etc. can be used to control them in real time.

All fields other than type, time, and channel are optional, and the
types and useage of the additional fields is defined in the file
SKINItbl.h.

The other important file used by SKINI is SKINImsg.h, which is a
set of #defines to make C code more readable, and to allow reasonably
quick re-mapping of control numbers, etc.. All of these defined
symbols are assigned integer values. For JAVA, the #defines could
be replaced by declaration and assignment statements, preserving
the look and behavior of the rest of the code.

4) C Files Used To Implement SKINI

Skini.cpp is an object which can either open a SKINI file, and
successively read and parse lines of text as SKINI strings, or
accept strings from another object and parse them. The latter
functionality would be used by a socket, pipe, or other connection
receiving SKINI messages a line at a time, usually in real time,
but not restricted to real time.

SKINImsg.h should be included by anything wanting to use the
Skini.cpp object. This is not mandatory, but use of the __SK_blah_
symbols which are defined in the .msg file will help to ensure
clarity and consistency when messages are added and changed.

SKINItbl.h is used only by the SKINI parser object (Skini.cpp).
In the file SKINItbl.h, an array of structures is declared and
assigned values which instruct the parser as to what the message
types are, and what the fields mean for those message types.
This table is compiled and linked into applications using SKINI, but
could be dynamically loaded and changed in a future version of
SKINI.

5) SKINI Messages and the SKINI Parser:

The parser isn't all that smart, but neither am I. Here are the
basic rules governing a valid SKINI message:

a) If the first (non-delimiter (see c)) character in a SKINI
string is '/' that line is treated as a comment and echoed
to stdout.

b) If there are no characters on a line, that line is treated
as blank and echoed to stdout. Tabs and spaces are treated
as non-characters.

c) Spaces, commas, and tabs delimit the fields in a SKINI
message line. (We might allow for multiple messages per
line later using the semicolon, but probably not. A series
of lines with deltaTimes of 0.0 denotes simultaneous events.
For read-ability, multiple messages per line doesn't help much,
so it's unlikely to be supported later).

d) The first field must be a SKINI message name. (like NoteOn).
These might become case-insensitive in future versions, so don't
plan on exciting clever overloading of names (like noTeOn being
different from NoTeON). There can be a number of leading
spaces or tabs, but don't exceed 32 or so.

e) The second field must be a time specification in seconds.
A time field can be either delta-time (most common and the only one
supported in version 0.8), or absolute time. Absolute time
messages have an '=' appended to the beginning of the floating
point number with no space. So 0.10000 means delta time of
100 ms, while =0.10000 means absolute time of 100 ms. Absolute
time messages make most sense in score files, but could also be
used for (loose) synchronization in a real-time context. Real
time messages should be time-ordered AND time-correct. That is,
if you've sent 100 total delta-time messages of 1.0 seconds, and
then send an absolute time message of =90.0 seconds, or if you
send two absolute time messages of =100.0 and =90.0 in that
order, things will get really fouled up. The SKINI parser
doesn't know about time, however. The WvOut device is the
master time keeper in the Synthesis Toolkit, so it should be
queried to see if absolute time messages are making sense.
There's an example of how to do that later in this document.
Absolute times are returned by the parser as negative numbers
(since negative deltaTimes are not allowed).

f) The third field must be an integer channel number. Don't go
crazy and think that this is just MIDI channel 0-15 (which is
supported). The channel number is scanned as a long int. Channels
0-15 are in general to be treated as MIDI channels. After that
it's wide open. Channels could be socket numbers, machine IDs,
serial numbers, or even unique tags for each event in a synthesis.
A -1 channel can be used as don't care, omni, or other functions
depending on your needs and taste.

g) All remaining fields are specified in the SKINItbl.h file.
In general, there are maximum two more fields, which are either
SK_INT (long), SK_DBL (double float), or SK_STR (string). The
latter is the mechanism by which more arguments can be specified
on the line, but the object using SKINI must take that string
apart (retrived by using getRemainderString()) and scan it.
Any excess fields are stashed in remainderString.

7) The SKINItbl.h File, How Messages are Parsed:

The SKINItbl.h file contains an array of structures which
are accessed by the parser object Skini.cpp. The struct is:

struct SKINISpec { char messageString[32];
long type;
long data2;
long data3;
};

so an assignment of one of these structs looks like:

MessageStr$ ,type, data2, data3,

type is the message type sent back from the SKINI line parser.
data<n> is either
NOPE : field not used, specifically, there aren't going
to be any more fields on this line. So if there
is is NOPE in data2, data3 won't even be checked
SK_INT : byte (actually scanned as 32 bit signed long int)
If it's a MIDI data field which is required to
be an integer, like a controller number, it's
0-127. Otherwise) get creative with SK_INTs
SK_DBL : double precision floating point. SKINI uses these
in the MIDI context for note numbers with micro
tuning, velocities, controller values, etc.
SK_STR : only valid in final field. This allows (nearly)
arbitrary message types to be supported by simply
scanning the string to EndOfLine and then passing
it to a more intellegent handler. For example,
MIDI SYSEX (system exclusive) messages of up to
256 bytes can be read as space-delimited integers
into the 1K SK_STR buffer. Longer bulk dumps,
soundfiles, etc. should be handled as a new
message type pointing to a FileName, Socket, or
something else stored in the SK_STR field, or
as a new type of multi-line message.

Here's a couple of lines from the SKINItbl.h file

{"NoteOff" , __SK_NoteOff_, SK_DBL, SK_DBL},
{"NoteOn" , __SK_NoteOn_, SK_DBL, SK_DBL},

{"ControlChange" , __SK_ControlChange_, SK_INT, SK_DBL},
{"Volume" , __SK_ControlChange_, __SK_Volume_ , SK_DBL},

{"StringDamping" , __SK_ControlChange_, __SK_StringDamping_, SK_DBL},
{"StringDetune" , __SK_ControlChange_, __SK_StringDetune_, SK_DBL},

The first three are basic MIDI messages. The first two would cause the
parser, after recognizing a match of the string "NoteOff" or "NoteOn",
to set the message type to 128 or 144 (__SK_NoteOff_ and __SK_NoteOn_
are #defined in the file SKINImsg.h to be the MIDI byte value, without
channel, of the actual MIDI messages for NoteOn and NoteOff). The parser
would then set the time or delta time (this is always done and is
therefore not described in the SKINI Message Struct). The next two
fields would be scanned as double-precision floats and assigned to
the byteTwo and byteThree variables of the SKINI parser. The remainder
of the line is stashed in the remainderString variable.

The ControlChange spec is basically the same as NoteOn and NoteOff, but
the second data byte is set to an integer (for checking later as to
what MIDI control is being changed).

The Volume spec is a MIDI Extension message, which behaves like a
ControlChange message with the controller number set explicitly to
the value for MIDI Volume (7). Thus the following two lines would
accomplish the same changing of MIDI volume on channel 2:

ControlChange 0.000000 2 7 64.1
Volume 0.000000 2 64.1

I like the 2nd line better, thus my motivation for SKINI in the first
place.

The StringDamping and StringDetune messages behave the same as
the Volume message, but use Control Numbers which aren't specifically
nailed-down in MIDI. Note that these Control Numbers are carried
around as long ints, so we're not limited to 0-127. If, however,
you want to use a MIDI controller to play an instrument, using
controller numbers in the 0-127 range might make sense.

8) Objects using SKINI

Here's a simple example of code which uses the Skini object
to read a SKINI file and control a single instrument.

Skini score;
Skini::Message message;
instrument = new Mandolin(50.0);
score.setFile( argv[1] );
while ( score.nextMessage( message ) != 0 ) {
tempDouble = message.time;
if (tempDouble < 0) {
tempDouble = - tempDouble;
tempDouble = tempDouble - output.getTime();
if (tempDouble < 0) {
printf("Bad News Here!!! Backward Absolute Time Required.\n");
tempDouble = 0.0;
}
}
tempLong = (long) ( tempDouble * Stk::sampleRate() );
for ( i=0; i<tempLong; i++ ) {
output.tick( instrument->tick() );
}

tempDouble3 = message.floatValues[1] * NORM_MIDI;
if ( message.type == __SK_NoteOn_ ) {
if ( tempDouble3 == 0.0 ) {
tempDouble3 = 0.5;
instrument->noteOff( tempDouble3 );
}
else {
tempLong = message.intValues[0];
tempDouble2 = Midi2Pitch[tempLong];
instrument->noteOn( tempDouble2, tempDouble3 );
}
}
else if ( message.type == __SK_NoteOff_ ) {
instrument->noteOff( tempDouble3 );
}
else if ( message.type == __SK_ControlChange_ ) {
tempLong = message.intValues[0];
instrument->controlChange( tempLong, tempDouble3 );
}
}

When a SKINI score is passed to a Skini object using the
Skini::setFile() function, valid messages are read from
the file and returned using the Skini::nextMessage() function.

A Skini::Message structure contains all the information parsed
from a single SKINI message. A returned message type of zero
indicates either an invalid message or the end of a scorefile.

The "time" member of a Skini::Message is the deltaTime until the
current message should occur. If this is greater than 0,
synthesis occurs until the deltaTime has elapsed. If deltaTime is
less than zero, the time is interpreted as absolute time and the
output device is queried as to what time it is now. That is used
to form a deltaTime, and if it's positive we synthesize. If it's
negative, we print an error, pretend this never happened and we
hang around hoping to eventually catch up.

The rest of the code sorts out message types NoteOn, NoteOff
(including NoteOn with velocity 0), and ControlChange. The
code implicitly takes into account the integer type of the
control number, but all other data is treated as double float.

/*! \page compile Compiling

The Synthesis ToolKit can be used in a variety of ways, depending on your particular needs. Some people choose the classes they need for a particular project and copy those to their working directory. Others create <TT>Makefiles</TT> that compile project-specific class objects from common <TT>src</TT> and <TT>include</TT> directories. And still others like to compile and link to a common library of object files. STK was not designed with one particular style of use in mind.


\section rtvsnonrt "Realtime" vs. "Non-Realtime"

Most of the Synthesis ToolKit classes are platform independent. That
means that they should compile on any reasonably current C++ compiler.
The functionality needed for realtime audio and MIDI input/output, as
well as realtime control message acquistion, is inherently platform
and operating-system (OS) <I>dependent</I>. STK classes that require
specific platform/OS support include RtAudio, RtWvOut, RtWvIn,
RtDuplex, RtMidi, InetWvIn, InetWvOut, Socket, UdpSocket, TcpServer,
TcpClient, Thread, and Mutex. These classes currently can only be
compiled on Linux, Macintosh OS X, and Windows systems.

Without the "realtime" classes, it is still possible to read SKINI
scorefiles for control input and to read and write to/from a variety
of audio file formats (WAV, SND, AIFF, MAT-file, and RAW). If
compiling for a "little-endian" host processor, the
<TT>__LITTLE_ENDIAN__</TT> preprocessor definition should be provided.


\section unix Unix Systems:

STK compiles with realtime support on the following flavors of the Unix operating system: Linux, Irix, and Macintosh OS X. Aside from differences in compilers, audio/MIDI APIs, and host endianness, the steps necessary to compile STK programs and classes on these platforms are the same. The following table summarizes these differences.

</CENTER>

The available C++ compilers on any of these systems can vary.

One approach in using STK is to simply copy the class files needed for
a particular program into a project directory. Taking the
<TT>sineosc.cpp</TT> example from the previous tutorial chapter, it
would be necessary to set up a directory that includes the files
<TT>sineosc.cpp</TT>, the rawwave file <TT>sinewave.raw</TT> in a
subdirectory called <TT>rawwaves</TT>, and the header and source files
for the classes Stk, FileRead, FileWrite, FileWvIn, FileLoop, and
FileWvOut. The program could then be compiled on a little-endian
system, such as a PC running Linux, using the GNU g++ compiler as
follows:
\code g++ -Wall -D__LITTLE_ENDIAN__ -o sineosc Stk.cpp FileRead.cpp FileWrite.cpp FileWvIn.cpp FileLoop.cpp FileWvOut.cpp sineosc.cpp \endcode

Note that the <TT>sineosc.cpp</TT> example does not make use of realtime audio or MIDI input/output classes. For programs using any of the STK realtime classes mentioned above, it is necessary to specify an audio/MIDI API preprocessor definition and link with the appropriate libraries or frameworks.

When working with a number of different projects that make use of ToolKit classes, the above approach can become cumbersome (especially when trying to synchronize with new STK releases). Most of the STK projects (e.g., demo, effects, ...) contain <TT>Makefiles</TT> (built by the configure script) that compile project-specific class objects from the distribution <TT>src</TT> and <TT>include</TT> directories. This approach makes it relatively easy when upgrading to a new STK release (by making path substitutions in the <TT>Makefile</TT> or by moving the projects to a similar relative path within the new STK source tree). A <TT>Makefile</TT> is provided in the <TT>projects/examples</TT> directory for compiling all the tutorial programs, as well as other example programs. To compile the <TT>sineosc.cpp</TT> program, for example, one need only type <TT>make sineosc</TT> from within the <TT>projects/examples</TT> directory.


\subsection library Library Use:

The STK distribution provides a <TT>Makefile</TT> that can be used on Unix systems to build a static library. After unpacking the distribution (<TT>tar -xzf stk-4.x.x.tar.gz</TT>), run the configure script by typing <TT>./configure</TT> from the top level distribution directory (see the INSTALL file in the same directory for more information). Then from within the <TT>src</TT> directory, type <TT>make</TT>. After a successful build, you may wish to move the library (<TT>libstk.a</TT>) and the contents of the <TT>include</TT> directory to standard library and include search paths on your system. For example, the linux RPM distribution of STK puts the library in <TT>/usr/lib/</TT> and the STK header files in <TT>/usr/include/stk/</TT>.

Assuming the library is located in a standard search path and the header files are located in <TT>/usr/include/stk/</TT>, the <TT>sineosc.cpp</TT> example from the previous tutorial chapter can be compiled on a little-endian system using the GNU g++ compiler as follows:

\code
g++ -Wall -D__LITTLE_ENDIAN__ -I/usr/include/stk -o sineosc sineosc.cpp -lstk
\endcode

With the header files in a standard search path, it is possible to modify the <TT>\#include</TT> statements in the <TT>sineosc.cpp</TT> program as follows:

\code
#include "stk/FileLoop.h"
#include "stk/FileWvOut.h"
\endcode

and then compile without an explicit include path argument to the compiler:

\code
g++ -Wall -D__LITTLE_ENDIAN__ -o sineosc sineosc.cpp -lstk
\endcode


\section compileWin Windows:

STK has been tested on Windows platforms using the Visual .NET compiler
only. It is assumed here that you're familiar with Visual C++ and its
particular idiosyncrasies. STK won't compile in Visual C++ 6.0 any more.

The approach when using Visual C++ is to build a project that
includes the necessary ToolKit files from the distribution
<TT>src</TT> and <TT>include</TT> directories. For the example
program from the previous tutorial chapter, create a VC++ console
application project, add the Stk, FileRead, FileWrite, WvIn, FileWvIn,
FileLoop, WvOut, and FileWvOut class files, as well as
<TT>sineosc.cpp</TT>, and make sure the <TT>sinewave.raw</TT> file is
in the subdirectory <TT>rawwaves</TT>.

For programs using any of the STK realtime classes mentioned above, it is necessary to link with the DirectSound (<TT>dsound.lib</TT>), <TT>winmm.lib</TT>, and <TT>Wsock32.lib</TT> libraries, select the multithreaded library, and provide the <TT>__LITTLE_ENDIAN__</TT>, <TT>__WINDOWS_DS__</TT>, and <TT>__WINDOWS_MM__</TT> preprocessor definitions.

For Steinberg ASIO support, use the <TT>__WINDOWS_ASIO__</TT> preprocessor definition (and the <TT>__WINDOWS_MM__</TT> definition for RtMidi support), include all the files in the <TT>src/asio/</TT> directory (i.e., <TT>asio.h,cpp</TT>, <TT>asiodrivers.h,cpp</TT>, ...), and link with the <TT>winmm.lib</TT>, and <TT>Wsock32.lib</TT> libraries.

/*! \page controlin Control Input

Each Synthesis ToolKit instrument exposes its relevant control parameters via public functions such as setFrequency() and controlChange(). Programmers are free to implement the control scheme of their choice in exposing those parameters to the user.

A text-based control protocol called <A HREF="skini.html">SKINI</A> is provided with the Synthesis ToolKit. SKINI extends the MIDI protocol in incremental ways, providing a text-based messaging scheme in human-readable format and making use of floating-point numbers wherever possible. Each SKINI message consists of a message type (e.g., NoteOn, PitchBend), a time specification (absolute or delta), a channel number (scanned as a long integer), and a maximum of two subsequent message-specific field values. Knowing this, it should be relatively clear what the following SKINI "scorefile" specifies:

\code
NoteOn 0.000082 2 55.0 82.3
NoteOff 1.000000 2 55.0 64.0
NoteOn 0.000082 2 69.0 82.8
StringDetune 0.100000 2 10.0
StringDetune 0.100000 2 30.0
StringDetune 0.100000 2 50.0
StringDetune 0.100000 2 40.0
StringDetune 0.100000 2 22.0
StringDetune 0.100000 2 12.0
NoteOff 1.000000 2 69.0 64.0
\endcode

MIDI messages are easily represented within the SKINI protocol.

The class stk::Messager can be used to acquire and parse MIDI messages
from a MIDI device and SKINI messages from STDIN and socket
connections. Incoming messages are acquired asynchronously and saved
to an internal message queue of stk::Skini::Message types (MIDI
messages are converted to the stk::Skini:Message format). The user
then uses the stk::Messager:popMessage() function to retrieve incoming
control messages. This function does not block, instead returning a
message type of zero when no more messages are in the queue. Many of
the example programs included with the ToolKit distribution use a
stk::Messager instance to accept control input from the accompanying tcl/tk
graphical user interfaces, from external MIDI devices, or from SKINI
scorefiles.

In the following example, we'll modify the <TT>bethree.cpp</TT> program from the previous tutorial chapter and incorporate a stk::Messager class to allow control via SKINI messages read from a SKINI file.

\include controlbee.cpp

A realtime control message will usually have a delta time of zero, in which case it is processed as soon as possible. Non-realtime messages, normally from a scorefile, will usually have non-zero delta times. The scheme used in this example is designed to work for both scorefile and realtime input types. When no message is available from the queue, the instrument is "ticked" for DELTA_CONTROL_TICKS and then the queue is checked again. The value of DELTA_CONTROL_TICKS roughly defines the program "control rate" in a realtime context, though multiple available messages in the queue are processed in immediate succession when their delta time values are zero.

The \c processMessage() function centralizes the handling of control messages. Other control update schemes can be implemented, perhaps using a separate thread or in the \c main() function, and this function should work in any context.

Assuming the program is compiled as <TT>controlbee</TT> and the SKINI scorefile <A HREF="tutorial/bookert.ski"><TT>bookert.ski</TT></A> is in the <TT>scores</TT> directory, the program can be run as:

\code
controlbee scores/bookert.ski
\endcode

Only a few basic SKINI message type case statements are included in this example. It is easy to extend the program to support a much more elaborate set of instrument control parameters.

This example could also be easily extended to accept "realtime" control input messages via pipe, socket or MIDI connections. The stk::Messager class provides stk::Messager::startStdInput(), stk::Messager::startSocketInput(), and stk::Messager::startMidiInput() functions for this purpose.

/*! \page crealtime Realtime Audio (callback)

An alternative scheme for audio input/output is to define a specific
function in which audio computations are performed and to let the
audio system call this function when more input/output data can be
accepted by the hardware (referred to as a callback scheme). In this
section, we show how the previous <TT>rtsine.cpp</TT> program can be
modified to work in a callback scenario. There is no "single-sample"
interface for this functionality. The callback function will be
invoked automatically by the audio system controller (RtAudio) when
new data is needed and it is necessary to compute a full audio buffer
of samples at that time (see \ref callback for further information).

The previous section described the use of the stk::RtWvOut class for
realtime audio output. The stk::RtWvOut::tick() function writes data to a
large ring-buffer, from which data is periodically written to the
computer's audio hardware via an underlying callback routine.

\include crtsine.cpp

The sinusoidal oscillator is created as before. The instantiation of
RtAudio requires quite a few more parameters, including output/input
device and channel specifiers, the data format, and the desired buffer
length (in frames). In this example, we request a single output
channel using the default output device, zero channels of input, the
RtAudio data format which corresponds to an <tt>StkFloat</tt>, and the
RT_BUFFER_SIZE defined in Stk.h. The \c bufferFrames argument is an
API-dependent buffering parameter (see RtAudio for further
information).

We also provide the audio system controller with a pointer to our
callback function and an optional pointer to data that will be made
available in the callback. In this example, we need to pass only the
pointer to the oscillator. In more complex programs, it is typically
necessary to put all shared data in a <tt>struct</tt> (see the next
tutorial program for an example) or make use of global variables.

Our callback routine is the \c tick() function. Function arguments
include pointers to the audio input and output data buffers, the
buffer size (in frames), a stream time argument, a status argument to
test for over/underruns, and the data pointer passed in the
openStream() function (if it exists). It is necessary to cast these
pointers to their corresponding data types before use. Our tick()
routine simply "ticks" the oscillator for \c nBufferFrames counts and
writes the result into the audio data buffer before returning.

The \c main() function blocks at the std::cin.get() call until the
user hits the "enter" key, after which the audio controller is shut
down and program execution ends.

\section callback Blocking vs. Callbacks

Prior to version 4.2.0, all STK example projects and programs used
blocking audio input/output functionality (typically with the RtWvIn,
RtWvOut, or RtDuplex classes). In many instances, a blocking scheme
results in a clearer and more straight-forward program structure.
Within a graphical user interface (GUI) programming context, however,
callback routines are often more natural.

In order to allow all STK programs to function with equal proficiency
on all supported computer platforms, a decision was made to modify the
example projects to use audio callback routines. The result is a more
complicated code structure, which is unfortunate given that we
generally strive to make STK code as clear as possible for educational
purposes. This was especially an issue with the demo program because
it is designed to function in both realtime and non-realtime contexts.
The use of global variables has been avoided by defining data
structures to hold all variables that must be accessible to the
callback routine and other functions. Alternative schemes for making
control updates could be designed depending on particular program
needs and constraints.

- Cleaned up Object.h a bit.
- Pulled various utility and thread functions out of syntmono.cpp (to aid readability of the code).

\subsection v2dot02 Version 2.02
- Created RawWave abstract class, with subclasses of RawLoop (looping rawwave oscillator), RawShot (non-looping, non-interpolating rawwave player ... used to be RawWvIn), and RawInterp (looping or non-looping, interpolating rawwave player ... used to be RawWave).
- Modified DrumSynt to correctly handle sample rates different than 22050 Hz.
- Modified syntmono parsing vs. tick routine so that some ticking occurs between each message. When multiple messages are waiting to be processed, the time between message updates is inversely proportional to the number of messages in the buffer.
- Fixed DirectSound playback bug in WinXX distribution. Sound was being played at 8-bit, 22 kHz in all cases. Playback is now 16-bit and dependent on SRATE.
- Fixed bug in MD2SKINI which prevented some NoteOff statements from being output.
- This distribution includes an example STK project, mus151, which demonstrates a means for keeping a user's personal projects separate from the main distribution. This is highly recommended, in order to simplify upgrades to future STK releases.

\subsection v2 Version 2
- Unification of the capabilities of STK across the various platforms. All of the previous SGI functionality has been ported to Linux and Windows, including realtime sound output and MIDI input.
- MIDI input (with optional time-stamping) supported on SGI, Linux (OSS device drivers only), and Windows operating systems. Time stamping under IRIX and Windows is quantized to milliseconds and under Linux to hundredths of a second.
- Various Sound Output Options - .wav, .snd, and .mat (Matlab MAT-file) soundfile outputs are supported on all operating systems. I hacked out the MAT-file structure, so you don't have to include any platform-specific libraries. Realtime sound output is provided as well, except under NeXTStep.
- Multiple Reverberator Implementations - Reverb subclasses of JCRev and NRev (popular reverberator implementations from CCRMA) have been written. Perry's original reverb implementation still exists as PRCRev. All reverberators now take a T60 initializer argument.
- MD2SKINI - A program which parses a MIDI input stream and spits out SKINI code. The output of MD2SKINI is typically piped into an STK instrument executable (eg. <tt>MD2SKINI | syntmono Clarinet -r -i</tt>). In addition, you can supply a filename argument to MD2SKINI and have it simultaneously record a SKINI score file for future reuse.
- Modifications to <I>Object.h</I> for OS_TYPE compilation dependencies. <I>Makefile</I> automatically determines OS_TYPE when invoked (if you have the GNU makefile utilities installed on your system).
- A single distribution for all platforms. The Unix and Windows versions have been merged into a single set of classes. Makefiles and Visual C++ workspace/project files are provided for compiling.

\section license Does STK have a license?

Yes, we finally made something official for release 4.3.0. It is listed in the Stk class and a few other places in the distribution, but I'll repeat it here for clarity:

\verbatim
The Synthesis ToolKit in C++ (STK) is a set of open source audio
signal processing and algorithmic synthesis classes written in the
C++ programming language. STK was designed to facilitate rapid
development of music synthesis and audio processing software, with
an emphasis on cross-platform functionality, realtime control,
ease of use, and educational example code. STK currently runs
with realtime support (audio and MIDI) on Linux, Macintosh OS X,
and Windows computer platforms. Generic, non-realtime support has
been tested under NeXTStep, Sun, and other platforms and should
work with any standard C++ compiler.

\endverbatim

\section filerate Why is my file sample rate wrong?

When the FileWvIn class loads a soundfile, it automatically sets its internal read increment based on the soundfile rate and the current STK sample rate. For example, if the current STK sample rate is 44100 Hz and the soundfile rate is 22050 Hz, the read increment, or rate, will be set to 0.5 and the file will be interpolated so that is sounds correct at 44100 Hz. For most cases, this works fine. However, consider the following example:

\code
FileWvIn input( "infile" ); // read an input soundfile
StkFloat sampleRate = input.getFileRate();
Stk::setSampleRate( sampleRate ); // set a new STK sample rate based on the file rate
\endcode

With version 4.3 and higher of STK, the FileWvIn class will be notified of a sample rate change and it will automatically adjust its read rate accordingly. Previous versions of STK did not perform this change and thus, the read rate could end up being incorrect. If you do not want FileWvIn to perform this automatic adjustment, you can call the \c ignoreSampleRateChange() function for a given class instance.

\section endianness Why does the sound I generated with STK sound like *&#@!?

If the resultant sound generated by an STK program sounds like noise (and you're not doing an MLS experiment), the problem is likely related to the byte "endianness" of your computer. By default, STK assumes "big endian" byte order. If you are working with STK classes on a PC (Windows or Linux), you \e must define the <TT>__LITTLE_ENDIAN__</TT> preprocessor definition \e before compiling. If after reading this you realize you need to make this change, do not forget to recompile all STK classes from scratch.

\section xwindows Why do I get a Tk display error message?

The following error may be printed to your terminal window (depending on the version of the tcl/tk interpreter you are running) if you attempt to start an STK tcl/tk interface without the X Server first running:

\code
Application initialization failed: this isn't a Tk applicationcouldn't connect to display ":0.0"
\endcode

Simply start your X server and then try the command again.

/*! \page filtering Using Filters

In this section, we demonstrate the use of a few of the STK filter classes. The stk::Iir class provides functionality to implement a generalized infinite impulse response (IIR) digital filter, similar to the \c filter function in Matlab. In this example, we create an stk::Iir instance and initialize it with specific numerator and denominator coefficients. We then compute its impulse response for 20 samples.

\code
#include "Iir.h"
using namespace stk;

int main()
{
StkFrames output( 20, 1 ); // initialize StkFrames to 20 frames and 1 channel (default: interleaved)
output[0] = 1.0;

std::vector<StkFloat> numerator( 5, 0.1 ); // create and initialize numerator coefficients
std::vector<StkFloat> denominator; // create empty denominator coefficients
denominator.push_back( 1.0 ); // populate our denomintor values
denominator.push_back( 0.3 );
denominator.push_back( -0.5 );

Iir filter( numerator, denominator );

filter.tick( output );
for ( unsigned int i=0; i<output.size(); i++ ) {
std::cout << "i = " << i << " : output = " << output[i] << std::endl;
}

return 0;
}
\endcode

The stk::Iir class implements the standard difference equation
\code
a[0]*y[n] = b[0]*x[n] + ... + b[nb]*x[n-nb] - a[1]*y[n-1] - ... - a[na]*y[n-na],
\endcode

where "b" values are numerator coefficients and "a" values are denominator coefficients. Note that if the first denominator coefficient is not 1.0, the Iir class automatically normalizes all filter coefficients by that value. The coefficient values are passed to the Iir class via a C++ <a href="http://www.roguewave.com/support/docs/sourcepro/stdlibref/vector.html">vector</a>, a container object provided by the C++ Standard Library.

Most STK classes use more specific types of digital filters, such as the stk::OneZero, stk::OnePole, stk::TwoPole, or stk::BiQuad varieties. These classes inherit from the stk::Filter abstract base class and provide specific functionality particular to their use, as well as functions to independently control individual coefficient values.

\section reson Resonances:

The STK stk::BiQuad and stk::TwoPole classes provide functionality for creating resonance filters. The following example demonstrates how to create a resonance centered at 440 Hz that is used to filter the output of a stk::Noise generator.

\code
#include "BiQuad.h"
#include "Noise.h"
using namespace stk;

int main()
{
StkFrames output( 20, 1 ); // initialize StkFrames to 20 frames and 1 channel (default: interleaved)
Noise noise;

BiQuad biquad;
biquad.setResonance( 440.0, 0.98, true ); // automatically normalize for unity peak gain

for ( unsigned int i=0; i<output.size(); i++ ) {
output[i] = biquad.tick( noise.tick() ); // single-sample computations
std::cout << "i = " << i << " : output = " << output[i] << std::endl;
}

return 0;
}
\endcode

By passing a boolian value of \c true as the third argument to the stk::BiQuad::setResonance() function, the filter coefficients are automatically scaled to achieve unity gain at the resonance peak frequency. The previous code could be easily modified for "vector-based" calculations:

\code
#include "BiQuad.h"
#include "Noise.h"
using namespace stk;

int main()
{
StkFrames output( 20, 1 ); // initialize StkFrames to 20 frames and 1 channel (default: interleaved)
Noise noise;

BiQuad biquad;
biquad.setResonance( 440.0, 0.98, true ); // automatically normalize for unity peak gain

biquad.tick( noise.tick( output ) ); // vector-based computations
for ( unsigned int i=0; i<output.size(); i++ ) {
std::cout << "i = " << i << " : output = " << output[i] << std::endl;
}

return 0;
}
\endcode

/*! \page fundamentals STK Fundamentals

The Synthesis ToolKit is implemented in the C++ programming language. STK does not attempt to provide a new programming environment or paradigm but rather provides a set of objects that can be used within a normal C++ programming framework. Therefore, it is expected that users of STK will have some familiarity with C/C++ programming concepts. That said, the STK classes do have some particular idiosyncrasies that we will mention here. Starting with STK version 4.4, all STK classes except RtAudio and RtMidi are defined within the stk namespace.

\section Signal Computations:

Audio and control signals throughout STK use a floating-point data type, <tt>StkFloat</tt>, the exact precision of which can be controlled via a typedef statement in Stk.h. By default, an StkFloat is a double-precision floating-point value. Thus, the ToolKit can use any normalization scheme desired. The base instruments and algorithms are implemented with a general audio sample dynamic maximum of +/-1.0.

In general, the computation and/or passing of values is performed on a "single-sample" basis. For example, the stk::Noise class outputs random floating-point numbers in the range +/-1.0. The computation of such values occurs in the stk::Noise::tick() function. The following program will generate 20 random floating-point (<tt>StkFloat</tt>) values in the range -1.0 to +1.0:

\code
#include "Noise.h"
using namespace stk;

int main()
{
StkFloat output;
Noise noise;

for ( unsigned int i=0; i<20; i++ ) {
output = noise.tick();
std::cout << "i = " << i << " : output = " << output << std::endl;
}

return 0;
}
\endcode

Nearly all STK classes implement <TT>tick()</TT> functions that take and/or return sample values. Within the <TT>tick()</TT> function, the fundamental sample calculations are performed for a given class. Most STK classes consume/generate a single sample per operation and their <TT>tick()</TT> method takes/returns each sample "by value". In addition, every class implementing a <TT>tick()</TT> function also provides one or more overloaded <TT>tick()</TT> functions that can be used for vectorized computations, as shown in the next example.

\code
#include "Noise.h"
using namespace stk;

int main()
{
StkFrames output(20, 1); // initialize StkFrames to 20 frames and 1 channel (default: interleaved)
Noise noise;

noise.tick( output );
for ( unsigned int i=0; i<output.size(); i++ ) {
std::cout << "i = " << i << " : output = " << output[i] << std::endl;
}

return 0;
}
\endcode

In this way, it might be possible to achieve improved processing efficiency using vectorized computations. The StkFrames class is a relatively new addition to the ToolKit to provide a general "mechanism" for handling and passing vectorized, multi-channel audio data. The StkFrames "type" provides functions to set and/or determine the number of audio channels and sample frames it holds. Further, the StkFrames class provides data interpolation and subscripting functionality by frame/channel values.

\section STK Inheritance:

Nearly all STK classes inherit from the Stk abstract base class, which provides common functionality related to error reporting, sample rate control, and byte swapping. Several other base classes exist that roughly group many of the classes according to function as follows:

- stk::Generator: source signal unit generator classes [stk::Envelope, stk::ADSR, stk::Asymp, stk::Noise, stk::SubNoise, stk::Modulate, stk::SingWave, stk::SineWave, stk::Blit, stk::BlitSaw, stk::BlitSquare, stk::Granulate]
- stk::Filter: digital filtering classes [stk::OneZero, stk::OnePole, stk::PoleZero, stk::TwoZero, stk::TwoPole, stk::BiQuad, stk::FormSwep, stk::Delay, stk::DelayL, stk::DelayA, stk::TapDelay]
- stk::Function: input to output function mappings [stk::BowTable, stk::JetTable, stk::ReedTable]
- stk::Instrmnt: sound synthesis algorithms, including physical, FM, modal, and particle models
- stk::Effect: sound processing effect classes [stk::Echo, stk::Chorus, stk::PitShift, stk::PRCRev, stk::JCRev, stk::NRev]
- stk::WvOut: audio data output classes [stk::FileWvOut, stk::RtWvOut, stk::InetWvOut]
- stk::WvIn: audio data input classes [stk::FileWvIn, stk::FileLoop, stk::RtWvIn, stk::InetWvIn]

/*! \page hello Hello Sine!

We'll continue our introduction to the Synthesis ToolKit with a simple
sine-wave oscillator program. STK provides two different classes for
sine-wave generation. We will first look at a generic waveform
oscillator class, stk::FileLoop, that can load a variety of common file
types. In this example, we load a sine "table" from an STK RAW file
(defined as monophonic, 16-bit, big-endian data). We use the class
stk::FileWvOut to write the result to a 16-bit, WAV formatted audio file.

\code

// sineosc.cpp

#include "FileLoop.h"
#include "FileWvOut.h"
using namespace stk;

int main()
{
// Set the global sample rate before creating class instances.
Stk::setSampleRate( 44100.0 );

FileLoop input;
FileWvOut output;

// Load the sine wave file.
input.openFile( "rawwaves/sinewave.raw", true );

// Open a 16-bit, one-channel WAV formatted output file
output.openFile( "hellosine.wav", 1, FileWrite::FILE_WAV, Stk::STK_SINT16 );

input.setFrequency( 440.0 );

// Run the oscillator for 40000 samples, writing to the output file
for ( int i=0; i<40000; i++ )
output.tick( input.tick() );

return 0;
}
\endcode

stk::FileLoop is a subclass of stk::FileWvIn, which supports WAV, SND
(AU), AIFF, MAT-file (Matlab), and RAW file formats with 8-, 16-, and
32-bit integer and 32- and 64-bit floating-point data types.
stk::FileWvIn provides interpolating, read-once ("oneshot")
functionality, as well as methods for setting the read rate and read
position.

stk::FileWvIn provides a "tick level" and interpolating interface to
the stk::FileRead class. Likewise, stk::FileWvOut provides a "tick
level" interface to the stk::FileWrite class. stk::FileRead and
FileWrite both support WAV, SND(AU), AIFF, MAT-file (Matlab), and RAW
file formats with 8-, 16-, and 32-bit integer and 32- and 64-bit
floating-point data types. stk::FileWvOut does not currently offer
data interpolation functionality.

A number of STK parent classes, including stk::WvIn, stk::WvOut,
stk::Instrmnt, stk::Generator, and stk::Effect, (and some or all of
their subclasses) support multi-channel sample frames. If a
single-sample version of the <TT>tick()</TT> function is called for
these classes, a full sample frame is computed but only a single value
is either input and/or output. For example, if the single-sample
<TT>tick()</TT> function is called for subclasses of stk::WvOut, the
sample argument is written to all channels in the one computed frame.
For classes returning values, an optional \c channel argument
specifies which channel value is returned from the computed frame (the
default is always channel 0). To input and/or output multichannel data
to these classes, the overloaded <TT>tick()</TT> functions taking
StkFrames reference arguments should be used.

Nearly all STK classes inherit from the stk::Stk base class. Stk
provides a static sample rate that is queried by subclasses as needed.
Because many classes use the current sample rate value during
instantiation, it is important that the desired value be set at the
beginning of a program. The default STK sample rate is 44100 Hz.

\section error Error Handling

The ToolKit has some basic C++ error handling functionality built in.
Classes that access files and/or hardware are most prone to runtime
errors. To properly "catch" such errors, the above example should be
rewritten as shown below.

\include sineosc.cpp

In this particular case, we simply exit the program if an error occurs
(an error message is automatically printed to stderr). A more refined
program might attempt to recover from or fix a particular problem and,
if successful, continue processing. See the \ref classes to determine
which constructors and functions can throw an error.

emphasis on cross-platform functionality, realtime control, ease of

portable (it's mostly platform-independent C and C++ code), and it's
completely user-extensible (all source included, no unusual libraries,
and no hidden drivers). We like to think that this increases the
chances that our programs will still work in another 5-10 years. In
fact, the ToolKit has been working continuously for nearly 20 years
now. STK currently runs with realtime support (audio and MIDI) on
Linux, Macintosh OS X, and Windows computer platforms. Generic,
non-realtime support has been tested under NeXTStep, Sun, and other

<H4>What is the <I>Synthesis ToolKit</I>?</H4>

The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language. STK was designed to facilitate rapid development of music synthesis and audio processing software, with an emphasis on cross-platform functionality, realtime control, ease of use, and educational example code. The Synthesis ToolKit is extremely portable (it's mostly platform-independent C and C++ code), and it's completely user-extensible (all source included, no unusual libraries, and no hidden drivers). We like to think that this increases the chances that our programs will still work in another 5-10 years. In fact, the ToolKit has been working continuously for nearly 20 years now. STK currently runs with realtime support (audio and MIDI) on Linux, Macintosh OS X, and Windows computer platforms. Generic, non-realtime support has been tested under NeXTStep, Sun, and other platforms and should work with any standard C++ compiler.

The Synthesis ToolKit is free. The only parts of the Synthesis ToolKit that are platform-dependent concern real-time audio and MIDI input and output, and that is taken care of with a few special classes. The interface for MIDI input and the simple <A HREF="http://dev.scriptics.com">Tcl/Tk</A> graphical user interfaces (GUIs) provided is the same, so it's easy to experiment in real time using either the GUIs or MIDI. The Synthesis ToolKit can generate simultaneous SND (AU), WAV, AIFF, and MAT-file output soundfile formats (as well as realtime sound output), so you can view your results using one of a large variety of sound/signal analysis tools already available (e.g. <A HREF="http://www-ccrma.stanford.edu/software/snd/">Snd</A>, Cool Edit, Matlab).


<H4>What the <I>Synthesis ToolKit</I> is not.</H4>

The Synthesis Toolkit is not one particular program. Rather, it is a set of C++ classes that you can use to create your own programs. A few example applications are provided to demonstrate some of the ways to use the classes. If you have specific needs, you will probably have to either modify the example programs or write a new program altogether. Further, the example programs don't have a fancy GUI wrapper. It is easy to embed STK classes inside a GUI environment but we have chosen to focus our energy on the audio signal processing issues. Spending hundreds of hours making platform-dependent graphical user interfaces would go against one of the fundamental design goals of the ToolKit - platform independence.

For those instances where a simple GUI with sliders and buttons is helpful, we use <A HREF="http://dev.scriptics.com">Tcl/Tk</A> (that is freely distributed for all the supported ToolKit platforms). A number of Tcl/Tk GUI scripts are distributed with the ToolKit release. For control, the Synthesis Toolkit uses raw MIDI (on supported platforms), and SKINI (Synthesis ToolKit Instrument Network Interface, a MIDI-like text message synthesis control format).

<H4>A brief history of the <I>Synthesis ToolKit in C++.</I></H4>

Perry Cook began developing a pre-cursor to the Synthesis ToolKit
(also called STK) under NeXTStep at the Center for Computer Research
in Music and Acoustics (CCRMA) at Stanford University in the
early-1990s. With his move to Princeton University in 1996, he ported
everything to C++ on SGI hardware, added real-time capabilities, and
greatly expanded the synthesis techniques available. With the help of
Bill Putnam, Perry also made a port of STK to Windows95. Gary Scavone
began using STK extensively in the summer of 1997 and completed a full
port of STK to Linux early in 1998. He finished the fully compatable
Windows port (using Direct Sound API) in June 1998. Numerous
improvements and extensions have been made since then.

The Toolkit has been distributed continuously since 1996 via the <A
HREF="http://www.music.princeton.edu/psk">Princeton Sound Kitchen</A>,
<A HREF="http://www.cs.princeton.edu/~prc">Perry Cook's home page</A>

Scavone's home page</A> at McGill University, and the <A HREF="http://ccrma.stanford.edu/software/stk">Synthesis ToolKit
home page</A>. The ToolKit has been included in various collections
of software. Much of it has also been ported to Max/MSP on Macintosh
computers by Dan Trueman and Luke Dubois of Columbia University, and
is distributed as <A
HREF="http://music.columbia.edu/PeRColate">PeRColate</A>. Help on
real-time sound and MIDI has been provided over the years by Tim
Stilson, Bill Putnam, and Gabriel Maldonado.

<H4>Disclaimer</H4>

STK is free and we do not guarantee anything. We've been hacking on this code for a while now and most of it seems to work pretty well. But, there surely are some bugs floating around. Sometimes things work fine on one computer platform but not so fine on another. FPU overflows and underflows cause <I>very</I> weird behavior that also depends on the particular CPU and OS. Let us know about bugs you find and we'll do our best to correct them.

<H4>Perry's Notes From the Original Distribution of STK</H4>

This whole world was created with no particular hardware in mind. These examples are intended to be tutorial in nature, as a platform for the continuation of my research, and as a possible starting point for a software synthesis system. The basic motivation was to create the necessary unit generators to do the synthesis, processing, and control that I want to do and teach about. Little thought for optimization was given and therefore improvements, especially speed enhancements, should be possible with these classes. It was written with some basic concepts in mind about how to let compilers optimize.

Your question at this point might be, "But Perry, with CMix, CMusic, CSound, CShells, CMonkeys, etc. already cluttering the landscape, why a new set of stupid C functions for music synthesis and processing?" The answers lie below.

<ol>
<li>I needed to port many of the things I've done into something that is generic enough to port further to different machines.</li>

<li>I really plan to document this stuff, so that you don't have to be me to figure out what's going on. (I'll probably be sorry I said this in a couple of years, when even I can't figure out what I was thinking.)</li>

<li>The classic difficulties most people have in trying to implement physical models are:

<ul>
<li>They have trouble understanding the papers, and/or in turning the theory into practice.</li>

<li>The physical model instruments are a pain to get to oscillate, and coming up with stable and meaningful parameter values is required to get the models to work at all.</li>
</ul>

This set of C++ unit generators and instruments might help to diminish the scores of emails I get asking what to do with those block diagrams I put in my papers.</li>

<li>I wanted to try some new stuff with modal synthesis, and implement some classic FM patches as well.</li>

<li>I wanted to reimplement, and newly implement more of the intelligent and physical performer models I've talked about in some of my papers. But I wanted to do it in a portable way, and in such a way that I can hook up modules quickly. I also wanted to make these instruments connectable to such player objects, so folks like Brad Garton who really think a lot about the players can connect them to my instruments, a lot about which I think.</li>

<li>More rationalizations to follow ...</li>
</ol>

/*! \page instruments Instruments

The ToolKit comes with a wide variety of synthesis algorithms, all of which inherit from the stk::Instrmnt class. In this example, we'll fire up an instance of the stk::BeeThree FM synthesis class and show how its frequency can be modified over time.

\include bethree.cpp

We have used an Instrmnt pointer when referencing the BeeThree
instance above, so it would be simple to replace the BeeThree class
with any other STK instrument class. It should be noted, however,
that a few classes do not respond to the setFrequency() function
(e.g., Shakers, Drummer).

The noteOn() function initiates an instrument attack. Instruments that are continuously excited (e.g., stk::Clarinet, stk::BeeThree) will continue to sound until stopped with a noteOff(). Impulsively excited instrument sounds (e.g., stk::Plucked, stk::Wurley) typically decay within a few seconds time, requiring subsequent noteOn() messages for re-attack.

Instrument parameters can be precisely controlled as demonstrated above. A more flexible approach to instrument control, allowing arbitrary scorefile or realtime updates, is described in the next tutorial chapter.

/*! \page multichannel Multi-Channel I/O

The ToolKit stk::WvIn and stk::WvOut classes (and their subclasses) support multi-channel audio data input and output. Several other abstract base classes, such as stk::Instrmnt, stk::Generator, and stk::Effect, also support multi-channel computations though not all of their subclasses produce or take multi-channel data. A set of interleaved audio samples representing a single time "slice" is referred to as a <I>sample frame</I>. At a sample rate of 44.1 kHz, a four-channel audio stream will have 44100 sample frames per second and a total of 176400 individual samples per second.

Most STK classes process single-sample data streams via their
<TT>tick()</TT> function. For classes supporting multi-channel data,
one must distinguish the <TT>tick()</TT> functions taking or producing
single \c StkFloat arguments from those taking stk::StkFrames& arguments. If
a single-sample version of the <TT>tick()</TT> function is called for
these classes, a full sample frame is computed but only a single value
is either input and/or output. For example, if the single-sample
<TT>tick()</TT> function is called for subclasses of WvOut, the sample
argument is written to all channels in the one computed frame. For
classes returning values, an optional \c channel argument specifies
which channel value is returned from the computed frame (the default
is always channel 0). To input and/or output multichannel data to
these classes, the overloaded <TT>tick()</TT> functions taking
StkFrames reference arguments should be used.

Multi-channel support for realtime audio input and output is dependent on the audio device(s) available on your system.

The following example demonstrates the use of the stk::FileWvOut class for
creating a four channel, 16-bit AIFF formatted audio file. We will
use four sinewaves of different frequencies for the first two seconds
and then a single sinewave for the last two seconds.

/*! \page polyvoices Voice Management

The previous tutorial chapters were concerned only with monophonic ToolKit instrument playback and control. At this point, it should be relatively clear that one can instantiate multiple instruments and perhaps sum together their outputs or even direct their outputs to separate channels. It is less clear how one might go about controlling a group of instruments. The stk::Voicer class is designed to serve just this purpose.

The stk::Voicer class is a relatively simple voice manager. The user can dynamically add and delete instruments to/from its "control", with the option of controlling specific instruments via unique note tags and/or grouping sets of instruments via a "group" number. All sounding instrument outputs are summed and returned via the <TT>tick()</TT> function. The stk::Voicer class responds to noteOn, noteOff, setFrequency, pitchBend, and controlChange messages, automatically assigning incoming messages to the voices in its control. When all voices are sounding and a new noteOn is encountered, the stk::Voicer interrupts the oldest sounding voice. The user is responsible for creating and deleting all instrument instances.

In the following example, we modify the <TT>controlbee.cpp</TT> program to make use of three stk::BeeThree instruments, all controlled using a stk::Voicer.

\include threebees.cpp

We have written this program to accept control messages from \c STDIN. Assuming the program is compiled as <TT>threebees</TT>, the three-voice SKINI scorefile <A HREF="tutorial/bachfugue.ski"><TT>bachfugue.ski</TT></A> (located in the <tt>scores</tt> directory with the examples) can be redirected to the program as:

\code
threebees < scores/bachfugue.ski
\endcode

For more fun, surf to <A HREF="http://kern.humdrum.net/">Kern Scores</A> for a huge assortment of other scorefiles that can be downloaded in the SKINI format.

Another easy extension would be to add the \c stk::Messager::startMidiInput() function to the program and then play the instruments via a MIDI keyboard.

/*! \page realtime Realtime Audio (blocking)

In this section, we modify the <TT>sineosc.cpp</TT> program in order
to send the output to the default audio playback device on your
computer system. We also make use of the stk::SineWave class as a
sine-wave oscillator. stk::SineWave computes an internal, static sine-wave
table when its first instance is created. Subsequent instances make
use of the same table. The default table length, specified in
SineWave.h, is 2048 samples.

\include rtsine.cpp

The class stk::RtWvOut is a protected subclass of stk::WvOut. A number of
optional constructor arguments can be used to fine tune its
performance for a given system. stk::RtWvOut provides a "single-sample",
blocking interface to the RtAudio class. Note that stk::RtWvOut (as well
as the stk::RtWvIn class described below) makes use of RtAudio's callback
input/output functionality by creating a large ring-buffer into which
data is written. These classes should not be used when low-latency
and robust performance is necessary

Though not used here, an stk::RtWvIn class exists as well that can be used
to read realtime audio data from an input device. See the
<TT>record.cpp</TT> example program in the <TT>examples</TT> project
for more information.

It may be possible to use an instance of stk::RtWvOut and an instance of
stk::RtWvIn to simultaneously read and write realtime audio to and from a
hardware device or devices. However, it is recommended to instead use
a single instance of RtAudio to achieve this behavior, as described in the next section.
See the <TT>effects</TT> project or the <TT>duplex.cpp</TT> example
program in the <TT>examples</TT> project for more information.

When using any realtime STK class (RtAudio, stk::RtWvOut, stk::RtWvIn, RtMidi, stk::InetWvIn, stk::InetWvOut, stk::Socket, stk::UdpSocket, stk::TcpServer, stk::TcpClient, and stk::Thread), it is necessary to specify an audio/MIDI API preprocessor definition and link with the appropriate libraries or frameworks. For example, the above program could be compiled on a Linux system using the GNU g++ compiler and the ALSA audio API as follows (assuming all necessary files exist in the project directory):

\code
g++ -Wall -D__LINUX_ALSA__ -D__LITTLE_ENDIAN__ -o rtsine Stk.cpp Generator.cpp SineWave.cpp WvOut.cpp \
RtWvOut.cpp RtAudio.cpp rtsine.cpp -lpthread -lasound
\endcode

On a Macintosh OS X system, the syntax would be:

\code
g++ -Wall -D__MACOSX_CORE__ -o rtsine Stk.cpp Generator.cpp SineWave.cpp WvOut.cpp RtWvOut.cpp RtAudio.cpp \
rtsine.cpp -lpthread -framework CoreAudio -framework CoreMIDI -framework CoreFoundation

/*! \page skini Synthesis toolKit Instrument Network Interface (SKINI)

This describes the latest (version 1.1) implementation of SKINI for the Synthesis ToolKit in C++ (STK) by Perry R. Cook.

Too good to be true?
Have control and read it too?
A SKINI haiku.
\endcode

Profound thanks to Dan trueman, Brad Garton, and Gary Scavone for input on this revision. Thanks also to MIDI, the NeXT MusicKit, ZIPI and all the creators and modifiers of these for good bases upon/from which to build and depart.

\section compatibility MIDI Compatibility

SKINI was designed to be MIDI compatible wherever possible, and extend MIDI in incremental, then maybe profound ways.

Differences from MIDI, and motivations, include:

- Text-based messages are used, with meaningful names wherever possible. This allows any language or system capable of formatted printing to generate SKINI. Similarly, any system capable of reading in a string and turning delimited fields into strings, floats, and ints can consume SKINI for control. More importantly, humans can actually read, and even write if they want, SKINI files and streams. Use an editor and search/replace or macros to change a channel or control number. Load a SKINI score into a spread sheet to apply transformations to time, control parameters, MIDI velocities, etc. Put a monkey on a special typewriter and get your next great work. Life's too short to debug bit/nybble packed variable length mumble messages. Disk space gets cheaper, available bandwidth increases, music takes up so little space and bandwidth compared to video and graphics. Live a little.

- Floating point numbers are used wherever possible. Note Numbers, Velocities, Controller Values, and Delta and Absolute Times are all represented and scanned as ASCII double-precision floats. MIDI byte values are preserved, so that incoming MIDI bytes from an interface can be put directly into SKINI messages. 60.0 or 60 is middle C, 127.0 or 127 is maximum velocity etc. But, unlike MIDI, 60.5 can cause a 50 cent sharp middle C to be played. As with MIDI byte values like velocity, use of the integer and SKINI-added fractional parts is up to the implementor of the algorithm being controlled by SKINI messages. But the extra precision is there to be used or ignored.

\section why Why SKINI?

SKINI was designed to be extensable and hackable for a number of applications: imbedded synthesis in a game or VR simulation, scoring and mixing tasks, real-time and non-real time applications which could benefit from controllable sound synthesis, JAVA controlled synthesis, or eventually maybe JAVA synthesis, etc. SKINI is not intended to be "the mother of scorefiles," but since the entire system is based on text representations of names, floats, and ints, converters from one scorefile language to SKINI, or back, should be easily created.

I am basically a bottom-up designer with an awareness of top-down design ideas, so SKINI above all reflects the needs of my particular research and creative projects as they have arisen and developed. SKINI 1.1 represents a profound advance beyond versions 0.8 and 0.9 (the first versions), future SKINI's might reflect some changes. Compatibility with prior scorefiles will be attempted, but there aren't that many scorefiles out there yet.

\section messages SKINI Messages

A basic SKINI message is a line of text. There are only three required fields, the message type (an ASCII name), the time (either delta or absolute), and the channel number. Don't freak out and think that this is MIDI channel 0-15 (which is supported), because the channel number is scanned as a long int. Channels could be socket numbers, machine IDs, serial numbers, or even unique tags for each event in a synthesis. Other fields might be used, as specified in the \c SKINI.tbl file. This is described in more detail later.

Fields in a SKINI line are delimited by spaces, commas, or tabs. The SKINI parser only operates on a line at a time, so a newline means the message is over. Multiple messages are NOT allowed directly on a single line (by use of the ; for example in C). This could be supported, but it isn't in version 1.1.

Message types include standard MIDI types like NoteOn, NoteOff, ControlChange, etc. MIDI extension message types (messages which look better than MIDI but actually get turned into MIDI-like messages) include LipTension, StringDamping, etc. Non-MIDI message types include SetPath (sets a path for file use later), and OpenReadFile (for streaming, mixing, and applying effects to soundfiles along with synthesis, for example). Other non-MIDI message types include Trilling, HammerOn, etc. (these translate to gestures, behaviors, and contexts for use by intelligent players and instruments using SKINI). Where possible I will still use these as MIDI extension messages, so foot switches, etc. can be used to control them in real time.

All fields other than type, time, and channel are optional, and the
types and useage of the additional fields is defined in the file \c
SKINI.tbl.

The other important file used by SKINI is \c SKINI.msg, which is a set of #defines to make C code more readable, and to allow reasonably quick re-mapping of control numbers, etc.. All of these defined symbols are assigned integer values. For Java, the #defines could be replaced by declaration and assignment statements, preserving the look and behavior of the rest of the code.

\section cfiles Files Used To Implement SKINI

Skini is a C++ class which can either open a SKINI file and successively read and parse lines of text as SKINI strings, or accept strings from another object and parse them. The latter functionality would be used by a socket, pipe, or other connection receiving SKINI messages a line at a time, usually in real time, but not restricted to real time.

\c SKINI.msg should be included by anything wanting to use the Skini object. This is not mandatory, but use of the __SK_blah_ symbols which are defined in the .msg file will help to ensure clarity and consistency when messages are added and changed.

\c SKINI.tbl is used only by the Skini parser object (Skini.cpp). In the file \c SKINI.tbl, an array of structures is declared and assigned values which instruct the parser as to what the message types are, and what the fields mean for those message types. This table is compiled and linked into applications using SKINI, but could be dynamically loaded and changed in a future version of SKINI.

\section parser SKINI Messages and the SKINI Parser:

The parser isn't all that smart, but neither am I. Here are the basic rules governing a valid SKINI message:

- If the first (non-delimiter ... see below) character in a SKINI string is '/' that line is treated as a comment and echoed to stdout.

- Spaces, commas, and tabs delimit the fields in a SKINI message line. (We might allow for multiple messages per line later using the semicolon, but probably not. A series of lines with deltaTimes of 0.0 denotes simultaneous events. For read-ability, multiple messages per line doesn't help much, so it's unlikely to be supported later).

- The first field must be a SKINI message name (like NoteOn). These might become case-insensitive in future versions, so don't plan on exciting clever overloading of names (like noTeOn being different from NoTeON). There can be a number of leading spaces or tabs, but don't exceed 32 or so.

- The second field must be a time specification in seconds. A time field can be either delta-time (most common and the only one supported in version 0.8), or absolute time. Absolute time messages have an '=' appended to the beginning of the floating point number with no space. So 0.10000 means delta time of 100 ms, while =0.10000 means absolute time of 100 ms. Absolute time messages make most sense in score files, but could also be used for (loose) synchronization in a real-time context. Real-time messages should be time-ordered AND time-correct. That is, if you've sent 100 total delta-time messages of 1.0 seconds, and then send an absolute time message of =90.0 seconds, or if you send two absolute time messages of =100.0 and =90.0 in that order, things will get really fouled up. The SKINI parser doesn't know about time, however. The WvOut device is the master time keeper in the Synthesis Toolkit, so it should be queried to see if absolute time messages are making sense. There's an example of how to do that later in this document. Absolute times are returned by the parser as negative numbers (since negative deltaTimes are not allowed).

- The third field must be an integer channel number. Don't go crazy and think that this is just MIDI channel 0-15 (which is supported). The channel number is scanned as a long int. Channels 0-15 are in general to be treated as MIDI channels. After that it's wide open. Channels could be socket numbers, machine IDs, serial numbers, or even unique tags for each event in a synthesis. A -1 channel can be used as don't care, omni, or other functions depending on your needs and taste.

- All remaining fields are specified in the \c SKINI.tbl file. In general, there are maximum two more fields, which are either SK_INT (long), SK_DBL (double float), or SK_STR (string). The latter is the mechanism by which more arguments can be specified on the line, but the object using SKINI must take that string apart (retrived by using getRemainderString()) and scan it. Any excess fields are stashed in remainderString.

\section table The SKINI.tbl File and Message Parsing:

The \c SKINI.tbl file contains an array of structures which are accessed by the parser object Skini.cpp. The struct is:

\code
struct SKINISpec {
char messageString[32];
long type;
long data2;
long data3;
};
\endcode

so an assignment of one of these structs looks like:

\code
MessageStr$ ,type, data2, data3,
\endcode

<TT>type</TT> is the message type sent back from the SKINI line parser.

<TT>data<n></TT> is either:

- NOPE : field not used, specifically, there aren't going to be any more fields on this line. So if there is is NOPE in data2, data3 won't even be checked.

- SK_INT : byte (actually scanned as 32 bit signed long int). If it's a MIDI data field which is required to be an integer, like a controller number, it's 0-127. Otherwise, get creative with SK_INTs.

- SK_DBL : double precision floating point. SKINI uses these in the MIDI context for note numbers with micro tuning, velocities, controller values, etc.

- SK_STR : only valid in final field. This allows (nearly) arbitrary message types to be supported by simply scanning the string to EOL (End Of Line) and then passing it to a more intelligent handler. For example, MIDI SYSEX (system exclusive) messages can be read as space-delimited integers into the SK_STR buffer. Longer bulk dumps, soundfiles, etc. should be handled as a new message type pointing to a FileName, Socket, or something else stored in the SK_STR field, or as a new type of multi-line message.

Each individual SKINI message is parsed and saved to a Skini::Message structure of the form:
\code
struct Message {
long type; /*!< The message type, as defined in SKINI.msg. */
long channel; /*!< The message channel (not limited to 16!). */
StkFloat time; /*!< The message time stamp in seconds (delta or absolute). */
std::vector<StkFloat> floatValues; /*!< The message values read as floats (values are type-specific). */
std::vector<long> intValues; /*!< The message values read as ints (number and values are type-specific). */
std::string remainder; /*!< Any remaining message data, read as ascii text. */
};
\endcode

Here's a couple of lines from the \c SKINI.tbl file

\code
{"NoteOff" , __SK_NoteOff_, SK_DBL, SK_DBL},
{"NoteOn" , __SK_NoteOn_, SK_DBL, SK_DBL},

{"ControlChange" , __SK_ControlChange_, SK_INT, SK_DBL},
{"Volume" , __SK_ControlChange_, __SK_Volume_ , SK_DBL},

{"StringDamping" , __SK_ControlChange_, __SK_StringDamping_, SK_DBL},
{"StringDetune" , __SK_ControlChange_, __SK_StringDetune_, SK_DBL},
\endcode

The first three are basic MIDI messages. The first two would cause the parser, after recognizing a match of the string "NoteOff" or "NoteOn", to set the message type to 128 or 144 (__SK_NoteOff_ and __SK_NoteOn_ are #defined in the file \c SKINI.msg to be the MIDI byte value, without channel, of the actual MIDI messages for NoteOn and NoteOff). The parser would then set the time or delta time (this is always done and is therefore not described in the SKINI Message Struct). The next two fields would be scanned either as double-precision \c floats or as <tt>long ints</tt>, depending on the format specified in \c SKINI.tbl, and saved to the corresponding C++ vector variables in the Skini::Message structure (either \c floatValues or \c intValues). Floating-point values are also cast to <tt>ints</tt> (and vice-versa) and stored to their respective variables. For example, an expected integer value of 64 will also be saved as 64.0 in the corresponding \c floatValues variable of the Skini::Message structure. The remainder of the line is stashed in the remainderString variable.

The ControlChange spec is basically the same as NoteOn and NoteOff, but the second data byte is set to an integer (for checking later as to what MIDI control is being changed).

The Volume spec is a MIDI Extension message, which behaves like a ControlChange message with the controller number set explicitly to the value for MIDI Volume (7). Thus the following two lines would accomplish the same changing of MIDI volume on channel 2:

\code
ControlChange 0.000000 2 7 64.1
Volume 0.000000 2 64.1
\endcode

I like the second line better, thus my motivation for SKINI in the first place.

The StringDamping and StringDetune messages behave the same as the Volume message, but use Control Numbers which aren't specifically nailed-down in MIDI. Note that these Control Numbers are carried around as long ints, so we're not limited to 0-127. If, however, you want to use a MIDI controller to play an instrument, using controller numbers in the 0-127 range might make sense.

\section using Using SKINI:

Here's a simple example of code which uses the Skini object to read a SKINI file and control a single instrument.

\code
Skini score;
Skini::Message message;
instrument = new Mandolin(50.0);
score.setFile( argv[1] );
while ( score.nextMessage( message ) != 0 ) {
tempDouble = message.time;
if (tempDouble < 0) {
tempDouble = - tempDouble;
tempDouble = tempDouble - output.getTime();
if (tempDouble < 0) {
printf("Bad News Here!!! Backward Absolute Time Required.\n");
tempDouble = 0.0;
}
}
tempLong = (long) ( tempDouble * Stk::sampleRate() );
for ( i=0; i<tempLong; i++ ) {
output.tick( instrument->tick() );
}

tempDouble3 = message.floatValues[1] * NORM_MIDI;
if ( message.type == __SK_NoteOn_ ) {
if ( tempDouble3 == 0.0 ) {
tempDouble3 = 0.5;
instrument->noteOff( tempDouble3 );
}
else {
tempLong = message.intValues[0];
tempDouble2 = Midi2Pitch[tempLong];
instrument->noteOn( tempDouble2, tempDouble3 );
}
}
else if ( message.type == __SK_NoteOff_ ) {
instrument->noteOff( tempDouble3 );
}
else if ( message.type == __SK_ControlChange_ ) {
tempLong = message.intValues[0];
instrument->controlChange( tempLong, tempDouble3 );
}
}
\endcode

When a SKINI score is passed to a Skini object using the Skini::setFile() function, valid messages are read from the file and returned using the Skini::nextMessage() function.

The "time" member of a Skini::Message is the deltaTime until the current message should occur. If this is greater than 0, synthesis occurs until the deltaTime has elapsed. If deltaTime is less than zero, the time is interpreted as absolute time and the output device is queried as to what time it is now. That is used to form a deltaTime, and if it's positive we synthesize. If it's negative, we print an error, pretend this never happened and we hang around hoping to eventually catch up.

The rest of the code sorts out message types NoteOn, NoteOff (including NoteOn with velocity 0), and ControlChange. The code implicitly takes into account the integer type of the control number, but all other data is treated as double float.

/*! \page tutorial Tutorial

The Synthesis ToolKit is a set of C++ classes. In order to go beyond the simple example programs we provide, it is necessary to know some basics about programming in C and C++. STK's "target audience" includes people who:
- want to create audio DSP and/or synthesis programs
- want to use our unit generators and input/output routines rather than code their own
- want to learn about synthesis and processing algorithms
- wish to teach real-time synthesis and processing and wish to use some of our classes and examples

Most ToolKit programmers will likely end up writing a class or two for their own particular needs, but this task is typically simplified by making use of pre-existing STK classes (filters, oscillators, etc.).

The following tutorial chapters describe many of the fundamental ToolKit concepts and classes. All tutorial programs are included in the <TT>projects/examples</TT> directory.

\section directory Directory Structure:

The top level distribution contains the following directories:

<UL>
<LI> The <I><B>src</B></I> directory contains the source .cpp files for all the STK unit generator and algorithm classes.</LI><P>

<LI> The <I><B>include</B></I> directory contains the header files for all the STK unit generator and algorithm classes.</LI><P>

<LI> The <I><B>projects</B></I> directory contains various demo and example STK programs.</LI><P>
</UL>

This release of STK comes with four separate "project" directories:

<OL>
<LI> The <I><B>demo</B></I> project is used to demonstrate nearly all of the STK instruments. The <I><B>stk-demo</B></I> program has been written to allow a variety of control input and sound data output options. Simple graphical user interfaces (GUIs) are also provided.<P></LI>

<LI> The <I><B>examples</B></I> project contains several simple programs that demonstrate audio input/output, including the audio internet streaming classes, as well as most of the tutorial programs.</LI>
</OL>

\section compiling Compiling:

<UL>
<LI><B>Windows95/98/2000/XP/7:</B> Realtime support is available using either DirectSound, ASIO or WASAPI audio drivers. For DirectSound support, use the <TT>__WINDOWS_DS__</TT> preprocessor definition and link with the <TT>dsound.lib</TT>, <TT>winmm.lib</TT>, and <TT>Wsock32.lib</TT> libraries. For ASIO support, use the <TT>__WINDOWS_ASIO__</TT> preprocessor definition, include all the files in the <TT>src/asio/</TT> directory (i.e. <TT>asio.h,cpp</TT>, <TT>asiodrivers.h,cpp</TT>, ...), and link with the <TT>winmm.lib</TT>, and <TT>Wsock32.lib</TT> libraries. For WASAPI support, use the <TT>__WINDOWS_WASAPI__</TT> preprocessor definition. In addition, the <TT>__LITTLE_ENDIAN__</TT> and <TT>__WINDOWS_MM__</TT> preprocessor definitions are necessary for all Windows systems (RtMidi uses the Windows MultiMedia MIDI API). Fairly old Visual C++ project files are provided in each project directory, though they may not work on newer versions of MSVS. As well, the MinGW compiler is supported (see below). It is important to link with the non-debug libraries when compiling "release" program versions and debug libraries when compiling "debug" program versions.</LI>

<LI><B>Unix (and MinGW) Systems:</B> A GNU <TT>configure</TT> shell script is included in the distribution for unix-based systems. From the top-level distribution directory, type <TT>'./configure'</TT> and the script will create <TT>Makefiles</TT> in each project directory specific to the characteristics of the host computer. Then from within any given project directory (example <TT>demo</TT>), type <TT>'make'</TT> to compile the project. In addition, an STK library can be compiled from within the <TT>src</TT> directory.

Several options can be supplied to the <TT>configure</TT> script to customize the build behavior:
<UL>
<LI><TT>--disable-realtime</TT> to only compile generic non-realtime classes</LI>
<LI><TT>--enable-debug</TT> to enable various debug output</LI>
<LI><TT>--with-alsa</TT> to choose native ALSA API support (default, linux only)</LI>
<LI><TT>--with-oss</TT> to choose native OSS audio API support (linux only, no native OSS MIDI support)</LI>
<LI><TT>--with-jack</TT> to choose native JACK API support (linux and Macintosh OS-X)</LI>
<LI><TT>--with-core</TT> to choose Core Audio API support (Macintosh OS-X)</LI>
<LI><TT>--with-asio</TT> to choose ASIO Audio API support (Windows)</LI>
<LI><TT>--with-ds</TT> to choose Windows Direct Sound Audio API support (Windows)</LI>
</UL>
<P>
Note that it is possible to specify as many of the "--with-" options as desired to compile multi-API support. In addition, it is possible to specify the location of the STK rawwaves and the STK include path as follows:
\code
./configure RAWWAVE_PATH="/home/gary/rawwaves/"
./configure INCLUDE_PATH="/home/gary/include/"
\endcode

For novice STK users, the default configuration should be adequate.
</UL>

For those who wish to create their own system-specific <TT>Makefiles</TT>:
<UL>
<LI><B>Linux:</B> Realtime audio support is enabled with either the <TT>__LINUX_ALSA__</TT>, <TT>__UNIX_JACK__</TT>, and/or <TT>__LINUX_OSS__</TT> preprocessor definitions, which are used to select the underlying audio system API(s). Because the ALSA library is now integrated into the standard Linux kernel, it is the default audio/MIDI API with STK versions 4.2 and higher. The <TT>__LINUX_ALSASEQ__</TT> preprocessor definition must be included for MIDI support. Note that native OSS MIDI support no longer exists in RtMidi. If the <TT>__LINUX_OSS__</TT> preprocessor definition is specified, only OSS (version 4.0) audio support will be compiled and RtMidi will still be compiled using the ALSA API (assuming the <TT>__LINUX_ALSASEQ__</TT> definition is defined). For this reason, STK now requires the <TT>asound</TT> library for realtime support. Realtime programs must also link with the <TT>pthread</TT> library. In addition, the <TT>__LITTLE_ENDIAN__</TT> preprocessor definition is necessary if compiling on a little-endian system. See the README-Linux file for further system configuration information.</LI>

<LI><B>Macintosh OS X:</B> Realtime support is enabled with the <TT>__MACOSX_CORE__</TT> and <TT>__UNIX_JACK__</TT> preprocessor definitions, which incorporate the CoreAudio audio/MIDI API and/or the JACK API. Realtime programs must also link with the <TT>pthread</TT> library and the <TT>CoreAudio</TT>, <TT>CoreMIDI</TT>, and <TT>CoreFoundation</TT> frameworks (for Core Audio support) and/or the JACK library. See the README-MacOSX file for further system configuration information.</LI>

<LI><B>Generic (non-realtime):</B> Most STK classes are operating system <I>independent</I> and can be compiled using any current C++ compiler. STK assumes big-endian host byte order by default, so if your system is little-endian (i.e. Intel processor), you must provide the <TT>__LITTLE_ENDIAN__</TT> preprocessor definition to your compiler. The <I><B>demo</B></I> project will compile without realtime support, allowing the use of SKINI scorefiles for input control and output to a variety of soundfile formats. The following classes <I>cannot</I> be used without realtime support: RtAudio, RtWvIn, RtWvOut, RtDuplex, RtMidi, Socket, Thread, Mutex, TcpWvIn, TcpWvOut. Because of this, it is not possible to compile the <I><B>effects</B></I>, <I><B>ragamatic</B></I>, and most of the <I><B>examples</B></I> projects for non-realtime use.</LI>
</UL>

\section debug Debugging:

When developing applications with STK, it is recommended that you define the preprocessor definition <TT>_STK_DEBUG_</TT> when compiling (or specify the <TT>--enable-debug</TT> option to the <TT>configure</TT> script). This will enable all levels of function argument and error checking within the STK classes. Without this definition, argument checking does not occur in functions that are expected to be called frequently in an iterative manner.

\section control Control Data:

All STK programs in this distribution take input control data in the form of <A HREF="skini.html">SKINI</A> or MIDI messages only. The Messager class unifies the various means of acquiring control data under a single, easy to use set of functions. The way that SKINI messages can be sent to the programs is dependent upon the operating system in use, as well as whether the program is running in realtime or not. In general, it is possible to:

<OL>
<LI>Redirect or pipe SKINI scorefiles to an executable.</LI>
<LI>Pipe realtime SKINI input messages to an executable (not possible under Windows95/98).</LI>
<LI>Acquire realtime MIDI messages from a MIDI port on your computer.</LI>
</OL>

<A HREF="http://dev.scriptics.com">Tcl/Tk</A> graphical user interfaces (GUI) are provided with this distribution that can generate realtime SKINI messages. Note that the Messager class allows multiple simultaneous socket client connections, together with MIDI and/or piped input. The <I><B>Md2Skini</B></I> program (in the <I><B>demo</B></I> directory) is mostly obsolete but can be used to create SKINI scorefiles from realtime MIDI input.


\section voices Demo: STK Instruments

The <I><B>demo</B></I> project demonstrates the behavior of all the distributed STK instruments. The instruments available with this release include:
<UL>
<LI>Clarinet: Pretty good physical model of the clarinet</LI>

</UL>

\section nort Demo: Non-Realtime Use

See the information above with respect to compiling STK for non-realtime use.

In non-realtime mode, it is assumed that input control messages are provided from a SKINI scorefile and that audio output is written to a soundfile (.snd, .wav, .aif, .mat, .raw). A number of SKINI scorefiles are provided in the <I>scores</I> directory of the <I><B>demo</B></I> project. Assuming a successful compilation of the <I><B>stk-demo</B></I> program, typing:

\code
stk-demo BeeThree -ow myfile.wav -if scores/bookert.ski
\endcode

from the <I><B>demo</B></I> directory will play the scorefile <I>bookert.ski</I> using the STK BeeThree instrument and write the resulting audio data to a WAV formatted soundfile called "myfile.wav" (note that you may need to append <TT>./</TT> to the program name if your default shell setup is not set to look in the current directory). Typing <TT>stk-demo</TT> without any arguments will provide a full program usage description.


\section rt Demo: Realtime Use

STK realtime audio and MIDI input/output and realtime SKINI control input via socketing support is provided for Linux, Mac OS-X, and Windows95/98/2000/XP operating systems. STK realtime SKINI control input via piping is possible under Linux, Mac OS X, and Windows2000/XP only.
<P>
Control input and audio output options are typically specified as command-line arguments to STK programs. For example, the <I><B>stk-demo</B></I> program is invoked as:

\code
stk-demo instrument flags
\endcode

where instruments include those described above and flags can be any or all of:
<UL>
<LI><I>-or</I> for realtime audio output,</LI>
<LI><I>-ow \<file name\></I> for WAV soundfile output,</LI>
<LI><I>-os \<file name\></I> for SND (AU) soundfile output,</LI>
<LI><I>-om \<file name\></I> for MAT-file output,</LI>
<LI><I>-if \<file name\></I> for a SKINI formatted control file,</LI>
<LI><I>-ip</I> for realtime SKINI control input via piping,</LI>
<LI><I>-im \<port\></I> for MIDI control input (with optional port, -1 = virtual port where possible),</LI>
<LI><I>-s RATE</I> to specify a sample rate,</LI>
<LI><I>-n NUMBER</I> to specify multivoice polyphony</LI>
</UL>
The <i>-ip</i> flag must be used when piping realtime SKINI control data to an STK program. The <i>-im</i> flag must be used to read MIDI control input from your MIDI port. Note that you can use both input types simultaneously.

Assuming a successful compilation of the <I><B>stk-demo</B></I> program, typing:

\code
stk-demo BeeThree -or -if scores/bookert.ski
\endcode

from the <I><B>demo</B></I> directory will play the scorefile <I>bookert.ski</I> using the STK BeeThree instrument and stream the resulting audio data in realtime to the audio output channel of your computer. Typing <TT>stk-demo</TT> without any arguments will provide a full program usage description.


\section tcl Realtime Control Input using Tcl/Tk Graphical User Interfaces:

There are a number of <A HREF="http://dev.scriptics.com">Tcl/Tk</A> GUIs supplied with the STK projects. These scripts require Tcl/Tk version 8.0 or later, which can be downloaded for free over the WWW. On Unix and Windows2000/XP platforms, you can run the various executable scripts (e.g. StkDemo.bat) provided with each project to start everything up (you may need to symbolically link the wishXX executable to the name <I>wish</I>). The Physical.bat script just implements the following command-line sequence:

\code
wish < tcl/Physical.tcl | stk-demo Clarinet -or -ip
\endcode

\section midi Realtime MIDI Control Input:

On all supported realtime platforms, you can direct realtime MIDI input to the STK Clarinet by typing:

\code
stk-demo Clarinet -or -im
\endcode

This will attempt to use the default MIDI port for input. An optional MIDI port number can be specified after the <TT>-im</TT> flag. Valid MIDI ports are numbered from 0 (default) and higher. On Linux and Macintosh OS-X systems, it is possible to open a virtual MIDI input port (that other software applications can connect to) by specifying a port identifier of -1.

\section polyphony Polyphony:

The <I><B>stk-demo</B></I> program supports an arbitrary number of voices via the <TT>-n NUMBER</TT> command-line flag and argument. For example, you can play eight BeeThree instruments with realtime output and control them from a MIDI device by typing:

\code
stk-demo BeeThree -n 8 -or -im
\endcode

<h3>How to Use Treesed</h3>

Go to the directory where you want to search or make changes.

<p>
There are two choices you can make when using treesed:
</p><ol>
<li>Do I just want to search for a text, or do I want to search for a
text and replace it with something else?
<br>
If you are just searching you are using Treesed in "search mode", otherwise it is in
"replace mode."
</li><li>Do I want to search/replace only in files in my current directory,
or should files in all subdirectories (and all directories below that)
also be done?
</li></ol>
Some examples will make this clear.

<h4>Searching</h4>
Say you are faced with the situation that the author of a slew of web-pages, Nathan Brazil, has left and has been succeeded by Mavra Chang. First, let us see which files are affected by this (what you type in is shown in <b><tt>bold</tt></b>):
<blockquote>
<pre>[localhost] <b>treesed "Nathan Brazil" -files *.html</b>
search_pattern: Nathan\ Brazil
replacement_pattern:

** Search mode

.
midnight.html: 1 lines on: 2
..
well.html: 1 lines on: 3
</pre>
</blockquote>
We notice the following:
<ul>
<li>The search text <tt>"Nathan Brazil"</tt> is enclosed in
double-quotes (<tt>"</tt>).
</li><li>You specify which files to search with <tt>-files</tt> followed by a
list of file names--in this case <tt>*.html</tt>.
</li><li>Treesed reports the search pattern ("pattern" is just a fancy word
for "text") you specified (you can ignore
that \).
</li><li>Treesed reports an empty <tt>replacement_pattern</tt>. This is
correct, because you haven't entered one.
</li><li>It therefore deduces that is is in search mode.
</li><li>It finds two files containing "Nathan Brazil", and reports on which
lines of these files it found it; it does not show the lines themselves.
</li></ul>
Because you used <tt>-files</tt>, Treesed will search in the files you
specify <i>in the current directory</i>. You can also search files in
the current directory <i>and</i> all directories below it. However, in
that case you can not specify which file names to use, all files will be
searched:
<blockquote>
<pre>[localhost] <b>treesed "Nathan Brazil" -tree</b>
search_pattern: Nathan\ Brazil
replacement_pattern:

** Search mode

.
midnight.html: 1 lines on: 2
...
well.html: 1 lines on: 3
.
new/echoes.html: 1 lines on: 2
</pre>
</blockquote>
We notice the following:
<ul>
<li>Instead of <tt>-files</tt> we now see <tt>-tree</tt>.
</li><li>We do not see a specification of file names.
</li><li>Treesed finds an occurence of "Nathan Brazil" in the file
<tt>echoes.html</tt> in the subdirectory <tt>new</tt>; it did not
find this file in the previous example (as it shouldn't).
</li></ul>

<h4>Replacing</h4>
To replace a text you simply add the replacement text right after the
search text:
<blockquote>
<pre>[localhost] <b>treesed "Nathan Brazil" "Mavra Change" -files *.html</b>
search_pattern: Nathan\ Brazil
replacement_pattern: Mavra Chang

** EDIT MODE!

.
midnight.html: 1 lines on: 2

Replaced Nathan\ Brazil by Mavra Chang on 1 lines in midnight.html
..
well.html: 1 lines on: 3

Replaced Nathan\ Brazil by Mavra Chang on 1 lines in well.html
</pre>
</blockquote>
We notice the following:
<ul>
<li>Right after the search text "Nathan Brazil" you specify the
replacement text "Mavra Chang".
</li><li>As a result, Treesed now reports a non-empty
<tt>replacement_pattern</tt>.
</li><li>Hence it concludes it is in "edit mode", which means replacment mode.
</li><li>Treesed dutifully reports on which lines in which files it did the
replacement.
</li></ul>
To replace a text in all files in the current directory and the ones
below it, we do the following:
<blockquote>
<pre>[localhost] <b>treesed "Nathan Brazil" "Mavra Chang" -tree</b>
search_pattern: Nathan\ Brazil
replacement_pattern: Mavra Chang

** EDIT MODE!

.
midnight.html: 1 lines on: 2

Replaced Nathan\ Brazil by Mavra Chang on 1 lines in midnight.html

....
well.html: 1 lines on: 3

Replaced Nathan\ Brazil by Mavra Chang on 1 lines in well.html
.
new/echoes.html: 1 lines on: 2

Replaced Nathan\ Brazil by Mavra Chang on 1 lines in new/echoes.html
</pre>
</blockquote>
and we get the expected results, including the replace in
<tt>new/echoes.html</tt>.

<h4>Old Versions</h4>
Treesed leaves behind quite a mess of old versions of the files it
changed (only in change-mode, of course). These old files have the same
name as the original file, with <tt>.ddddd</tt> appended to it. For
example, if treesed makes a change to <tt>midnight.html</tt> it will
leave the original version as something like
<tt>midnight.html.26299</tt>. You'll have to remove these files lest
your disk area clutters up. Here is a command that does that, <b>but
beware!</b> This command removes all files in the current directory and
all below it, that end in a period followed by one or more
digits:
<blockquote>
<pre>find . -name "*.[0-9]*" -exec rm {} \;
</pre>
</blockquote>

It is interesting to note that if you use treesed again without cleaning
up, you may get files like <tt>midnight.html.26299.27654</tt>. These
will also be cleaned up by the above slightly dangerous command.

This file contains instructions for integrating the STK in Xcode projects and solutions to common integration issues.

## Setup

### If you have [Cocoapods](http://cocoapods.org/)

1. Add `pod 'STK', '~> 4.5'` to your Podfile.

1. Run `pod install`

### If you don't have Cocoapods

1. Clone or [download][download_link] the STK into your project's directory.

1. Open the **STK for iOS** folder, and drag and drop **STK.xcodeproj** into your Xcode project.

1. Open your project's settings, open the *Build Phases* tab. In the *Link Binary with Libraries* section, add **libSTK.a**.
![][linking_libSTK_screenshot]

1. In your project's settings, open the *Build Settings* tab. In the *Search Paths* section, double click on the field to the right of *Header Search Paths*, and add the path to the STK's **include** directory relative to your Xcode project's directory.
![][header_search_paths_screenshot]


## Usage

1. Import the STK classes in the source files you require.
* E.g. `#import "SineWave.h"`

1. Change the extension of Objective-C files that import STK files to **.mm**.
* E.g. **ViewController.m** —> **ViewController.mm**

You can also look at the [iOS Demo project](..projects/demo/iOS%20Demo) for a sample usage.


## Troubleshooting

### 'FileName.h' file not found

If you get this error when `#import`ing an STK header, you have added the wrong header search path for the STK in your project's settings (see Step 4 in Setup)

The STK's header search path you need to add is the path to the STK's **include** directory relative to your project's directory (as if you were `cd`ing into it). For example, it is `stk/include/` if the stk directory is inside your project's directory, but it is `../stk/include/` if both share the same directory.

If this problem doesn't go away:

1. Delete **STK.xcodeproj** from your Xcode project
1. Move the STK directory within your project's directory.
1. Follow step 1 from **Setup**, add `stk/include` to the *Header Search Paths*.

If that doesn't solve it:
Install Cocoapods and use it to install the STK. It takes one minute and will make your life easier. Visit the [Cocoapods website](http://cocoapods.org/) for installation instructions.

### FileRead::open: could not open or find file (../../rawwaves/filename.raw)!

If you use a class that makes use of raw waves (such as `Mandolin`, `Wurley`, or `Rhodey`) you need to make sure that the STK's raw wave files are copied into your bundle and that the STK knows where they are. You'll know you need to if you get this runtime error:
`FileRead::open: could not open or find file (../../rawwaves/filename.raw)!`

#### If you're using Cocoapods

Add this code before using a class that needs the raw waves:
```objective-c
stk::Stk::setRawwavePath([[[NSBundle mainBundle] pathForResource:@"rawwaves" ofType:@"bundle"] UTF8String]);
```

#### If you're not using Cocoapods

1. Open your project's settings, open the *Build Phases* tab.
1. In the *Copy Bundle Resources*, drag and drop **rawwaves.bundle** (it's located in **STK.xcodeproj**'s **Helpers** folder).
1. Then add this code before using a class that needs the raw waves:

```objective-c
NSBundle *rawwaveBundle = [NSBundle bundleWithURL:[[NSBundle mainBundle] URLForResource:@"rawwaves" withExtension:@"bundle"]];
stk::Stk::setRawwavePath([[rawwaveBundle resourcePath] UTF8String]);
```


### rawwaves.bundle: No such file or directory

This means that **rawwaves.bundle** hasn't been copied to the build folder, so you'll need to do it manually:

Select the rawwaves scheme:

![][rawwaves_scheme_screenshot]
Build it (⌘+B) then build your project's main scheme.

### Apple Mach-O Linker Error

This means that **STKLib.a** isn't being linked to your binary. Follow step 2 above in [Setup](#setup).

##iOS Demo Xcode project

This project briefly shows how to manually integrate the STK static library into an Xcode project. See the **README** file in the STK's `iOS` directory for precise instructions.

Currently, this project does not output sound, it only shows how to generate audio samples from the STK classes within an iOS project, and how to control STK objects via UI controls.

Note the following:

* ViewController needs to be renamed with the **.mm** extension as it's importing STK files, which are C++.
* The header search paths in the *Build Settings* of **iOS Demo.xcodeproj** point to `../../include/` because the STK's `include` directory is two directories up relative to it.

/*! \class Asymp
\brief STK asymptotic curve envelope class

This class implements a simple envelope generator
which asymptotically approaches a target value.
The algorithm used is of the form:

y[n] = a y[n-1] + (1-a) target,

where a = exp(-T/tau), T is the sample period, and
tau is a time constant. The user can set the time
constant (default value = 0.3) and target value.
Theoretically, this recursion never reaches its
target, though the calculations in this class are
stopped when the current value gets within a small
threshold value of the target (at which time the
current value is set to the target). It responds
to \e keyOn and \e keyOff messages by ramping to
1.0 on keyOn and to 0.0 on keyOff.

\brief STK band-limited impulse train class.

This class generates a band-limited impulse train using a
closed-form algorithm reported by Stilson and Smith in "Alias-Free
Digital Synthesis of Classic Analog Waveforms", 1996. The user
can specify both the fundamental frequency of the impulse train
and the number of harmonics contained in the resulting signal.

The signal is normalized so that the peak value is +/-1.0.

If nHarmonics is 0, then the signal will contain all harmonics up
to half the sample rate. Note, however, that this setting may
produce aliasing in the signal when the frequency is changing (no
automatic modification of the number of harmonics is performed by
the setFrequency() function).

This function sets the number of harmonics contained in the

harmonic content (harmonics up to half the sample rate). This
parameter is not checked against the current sample rate and
fundamental frequency. Thus, aliasing can result if one or more
harmonics for a given fundamental frequency exceeds fs / 2. This
behavior was chosen over the potentially more problematic solution
of automatically modifying the M parameter, which can produce
audible clicks in the signal.
