+   There is a need for an API that supports hosted MIDI soft synths
+   with GUIs in Linux audio applications.  In time the GMPI initiative
+   should comprehensively address this need, but the requirement for
+   Linux applications to be able to support simple hosted synths is
+   here now, and GMPI is not.  This proposal (the "DSSI Soft Synth
+   Interface" or DSSI, pronounced "dizzy") aims to provide a simple
+   solution in a way that we hope will prove complete and compelling
+   enough to support now, yet not so compelling as to supplant GMPI or
+   any other comprehensive future proposal.
+
+   For simplicity and familiarity, this API is based as far as
+   possible on existing work -- the LADSPA plugin API for control
+   values and audio processing, and the ALSA sequencer event types for
+   MIDI event communication.  The GUI part of the proposal is quite
+   new, but may also be applicable retroactively to LADSPA plugins
+   that do not otherwise support this synth interface.

+     * that does not require this facility at all may set this member
+     * to NULL.
+     *
+     * This call is intended to set some session-scoped aspect of a

+     * sample data from a particular file.  The plugin should act
+     * immediately on the request.  The call should return NULL on
+     * success, or an error string that may be shown to the user.  The
+     * host will free the returned value after use if it is non-NULL.
+     *
+     * Calls to configure() are not automated as timed events.
+     * Instead, a host should remember the last value associated with
+     * each key passed to configure() during a given session for a
+     * given plugin instance, and should call configure() with the
+     * correct value for each key the next time it instantiates the

+     * Reserved and special key prefixes
+     * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+     * The DSSI: prefix
+     * ----------------
+     * Configure keys starting with DSSI: are reserved for particular
+     * purposes documented in the DSSI specification.  At the moment,
+     * there is one such key: DSSI:PROJECT_DIRECTORY.  A host may call
+     * configure() passing this key and a directory path value.  This
+     * indicates to the plugin and its UI that a directory at that
+     * path exists and may be used for project-local data.  Plugins
+     * may wish to use the project directory as a fallback location
+     * when looking for other file data, or as a base for relative
+     * paths in other configuration values.
+     *
+     * The GLOBAL: prefix
+     * ------------------
+     * Configure keys starting with GLOBAL: may be used by the plugin
+     * and its UI for any purpose, but are treated specially by the
+     * host.  When one of these keys is used in a configure OSC call
+     * from the plugin UI, the host makes the corresponding configure
+     * call (preserving the GLOBAL: prefix) not only to the target
+     * plugin but also to all other plugins in the same instance
+     * group, as well as their UIs.  Note that if any instance
+     * returns non-NULL from configure to indicate error, the host
+     * may stop there (and the set of plugins on which configure has
+     * been called will thus depend on the host implementation).

+     * 2. A host must not attempt to switch notes off by sending
+     * zero-velocity NOTE_ON events.  It should always send true
+     * NOTE_OFFs.  It is the host's responsibility to remap events in
+     * cases where an external MIDI source has sent it zero-velocity
+     * NOTE_ONs.

+     * Bank and Program Events
+     * ~~~~~~~~~~~~~~~~~~~~~~~

+     * controllers and MIDI Program Change events onto the banks and
+     * programs specified by the plugin, using the DSSI select_program

+/* Overview: 
+
+   There is a large number of synthesis packages in use or development
+   on the Linux platform at this time. This API (`The Linux Audio
+   Developer's Simple Plugin API') attempts to give programmers the
+   ability to write simple `plugin' audio processors in C/C++ and link
+   them dynamically (`plug') into a range of these packages (`hosts').
+   It should be possible for any host and any plugin to communicate
+   completely through this interface.
+
+   This API is deliberately short and simple. To achieve compatibility
+   with a range of promising Linux sound synthesis packages it
+   attempts to find the `greatest common divisor' in their logical
+   behaviour. Having said this, certain limiting decisions are
+   implicit, notably the use of a fixed type (LADSPA_Data) for all
+   data transfer and absence of a parameterised `initialisation'
+   phase. See below for the LADSPA_Data typedef.
+
+   Plugins are expected to distinguish between control and audio
+   data. Plugins have `ports' that are inputs or outputs for audio or
+   control data and each plugin is `run' for a `block' corresponding
+   to a short time interval measured in samples. Audio data is
+   communicated using arrays of LADSPA_Data, allowing a block of audio
+   to be processed by the plugin in a single pass. Control data is
+   communicated using single LADSPA_Data values. Control data has a
+   single value at the start of a call to the `run()' or `run_adding()'
+   function, and may be considered to remain this value for its
+   duration. The plugin may assume that all its input and output ports
+   have been connected to the relevant data location (see the
+   `connect_port()' function below) before it is asked to run.
+
+   Plugins will reside in shared object files suitable for dynamic
+   linking by dlopen() and family. The file will provide a number of
+   `plugin types' that can be used to instantiate actual plugins
+   (sometimes known as `plugin instances') that can be connected
+   together to perform tasks.
+
+   This API contains very limited error-handling. */

+   is used to communicate audio samples and control values. It is
+   assumed that the plugin will work sensibly given any numeric input
+   value although it may have a preferred range (see hints below). 
+
+   For audio it is generally assumed that 1.0f is the `0dB' reference
+   amplitude and is a `normal' signal level. */

+   management within its run() or run_adding() functions. All new
+   memory used in run() must be managed via the stack. These
+   restrictions only apply to the run() function.
+
+   (2) The plugin will not attempt to make use of any library
+   functions with the exceptions of functions in the ANSI standard C
+   and C maths libraries, which the host is expected to provide.
+
+   (3) The plugin will not access files, devices, pipes, sockets, IPC
+   or any other mechanism that might result in process or thread
+   blocking.
+      
+   (4) The plugin will take an amount of time to execute a run() or
+   run_adding() call approximately of form (A+B*SampleCount) where A
+   and B depend on the machine and host in use. This amount of time
+   may not depend on input signals or plugin state. The host is left

+/**
+   @file forge.h An API for constructing LV2 atoms.
+
+   This file provides an API for constructing Atoms which makes it relatively
+   simple to build nested atoms of arbitrary complexity without requiring
+   dynamic memory allocation.
+
+   The API is based on successively appending the appropriate pieces to build a
+   complete Atom.  The size of containers is automatically updated.  Functions
+   that begin a container return (via their frame argument) a stack frame which
+   must be popped when the container is finished.
+
+   All output is written to a user-provided buffer or sink function.  This
+   makes it popssible to create create atoms on the stack, on the heap, in LV2
+   port buffers, in a ringbuffer, or elsewhere, all using the same API.
+
+   This entire API is realtime safe if used with a buffer or a realtime safe
+   sink, except lv2_atom_forge_init() which is only realtime safe if the URI
+   map function is.
+
+   Note these functions are all static inline, do not take their address.
+
+   This header is non-normative, it is provided for convenience.

+/** This data structure is used to contain the MIDI events for one run() 
+    cycle. The port buffer for a LV2 port that has the datatype 
+    <http://ll-plugins.nongnu.org/lv2/ext/miditype> should be a pointer 
+    to an instance of this struct. 
+
+    To store two Note On events on MIDI channel 0 in a buffer, with timestamps
+    12 and 35.5, you could use something like this code (assuming that 
+    midi_data is a variable of type LV2_MIDI):
+    @code
+    
+      size_t buffer_offset = 0;
+      *(double*)(midi_data->data + buffer_offset) = 12;
+      buffer_offset += sizeof(double);
+      *(size_t*)(midi_data->data + buffer_offset) = 3;
+      buffer_offset += sizeof(size_t);
+      midi_data->data[buffer_offset++] = 0x90;
+      midi_data->data[buffer_offset++] = 0x48;
+      midi_data->data[buffer_offset++] = 0x64;
+      ++midi_data->event_count;
+      
+      *(double*)(midi_data->data + buffer_offset) = 35.5;
+      buffer_offset += sizeof(double);
+      *(size_t*)(midi_data->data + buffer_offset) = 3;
+      buffer_offset += sizeof(size_t);
+      midi_data->data[buffer_offset++] = 0x90;
+      midi_data->data[buffer_offset++] = 0x55;
+      midi_data->data[buffer_offset++] = 0x64;
+      ++midi_data->event_count;
+      
+      midi_data->size = buffer_offset;
+      
+    @endcode
+    
+    This would be done by the host in the case of an input port, and by the
+    plugin in the case of an output port. Whoever is writing events to the
+    buffer must also take care not to exceed the capacity of the data buffer.
+    
+    To read events from a buffer, you could do something like this:
+    @code
+    
+      size_t buffer_offset = 0;
+      uint32_t i;
+      for (i = 0; i < midi_data->event_count; ++i) {
+        double timestamp = *(double*)(midi_data->data + buffer_offset);
+        buffer_offset += sizeof(double);
+        size_t size = *(size_t*)(midi_data->data + buffer_offset);
+        buffer_offset += sizeof(size_t);
+        do_something_with_event(timestamp, size, 
+                                midi_data->data + buffer_offset);
+        buffer_offset += size;

+  /** The data buffer that is used to store MIDI events. The events are packed
+      after each other, and the format of each event is as follows:
+      
+      First there is a timestamp, which should have the type "double",
+      i.e. have the same bit size as a double and the same bit layout as a 
+      double (whatever that is on the current platform). This timestamp gives 
+      the offset from the beginning of the current cycle, in frames, that 
+      the MIDI event occurs on. It must be strictly smaller than the 'nframes'
+      parameter to the current run() call. The MIDI events in the buffer must 
+      be ordered by their timestamp, e.g. an event with a timestamp of 123.23
+      must be stored after an event with a timestamp of 65.0.
+      
+      The second part of the event is a size field, which should have the type
+      "size_t" (as defined in the standard C header stddef.h). It should 
+      contain the size of the MIDI data for this event, i.e. the number of 
+      bytes used to store the actual MIDI event. The bytes used by the 
+      timestamp and the size field should not be counted.
+      
+      The third part of the event is the actual MIDI data. There are some
+      requirements that must be followed:
+      
+      * Running status is not allowed. Every event must have its own status 
+        byte.
+      * Note On events with velocity 0 are not allowed. These events are 
+        equivalent to Note Off in standard MIDI streams, but in order to make
+        plugins and hosts easier to write, as well as more efficient, only
+        proper Note Off events are allowed as Note Off. 
+      * "Realtime events" (status bytes 0xF8 to 0xFF) are allowed, but may not
+        occur inside other events like they are allowed to in hardware MIDI 
+        streams.
+      * All events must be fully contained in a single data buffer, i.e. events
+        may not "wrap around" by storing the first few bytes in one buffer and
+        then wait for the next run() call to store the rest of the event. If 
+        there isn't enough space in the current data buffer to store an event,
+        the event will either have to wait until next run() call, be ignored,
+        or compensated for in some more clever way.
+      * All events must be valid MIDI events. This means for example that
+        only the first byte in each event (the status byte) may have the eighth
+        bit set, that Note On and Note Off events are always 3 bytes long etc.
+        The MIDI writer (host or plugin) is responsible for writing valid MIDI
+        events to the buffer, and the MIDI reader (plugin or host) can assume
+        that all events are valid.
+        
+      On a platform where double is 8 bytes and size_t is 4 bytes, the data 
+      buffer layout for a 3-byte event followed by a 4-byte event may look 
+      something like this:
+      _______________________________________________________________
+      | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ...
+      |TIMESTAMP 1    |SIZE 1 |DATA |TIMESTAMP 2    |SIZE 2 |DATA   | ...
