 | |||
JUCE is an open-source cross-platform C++ application framework for creating high quality | |||
desktop and mobile applications, including VST, VST3, AU, AUv3, RTAS and AAX audio plug-ins. | |||
JUCE can be easily integrated with existing projects via CMake, or can be used as a project | |||
generation tool via the [Projucer](https://juce.com/discover/projucer), which supports | |||
exporting projects for Xcode (macOS and iOS), Visual Studio, Android Studio, Code::Blocks | |||
and Linux Makefiles as well as containing a source code editor. | |||
## Getting Started | |||
The JUCE repository contains a [master](https://github.com/juce-framework/JUCE/tree/master) | |||
and [develop](https://github.com/juce-framework/JUCE/tree/develop) branch. The develop branch | |||
contains the latest bugfixes and features and is periodically merged into the master | |||
branch in stable [tagged releases](https://github.com/juce-framework/JUCE/releases) | |||
(the latest release containing pre-built binaries can be also downloaded from the | |||
[JUCE website](https://juce.com/get-juce)). | |||
JUCE projects can be managed with either the Projucer (JUCE's own project-configuration | |||
tool) or with CMake. | |||
### The Projucer | |||
The repository doesn't contain a pre-built Projucer so you will need to build it | |||
for your platform - Xcode, Visual Studio and Linux Makefile projects are located in | |||
[extras/Projucer/Builds](/extras/Projucer/Builds) | |||
(the minimum system requirements are listed in the __System Requirements__ section below). | |||
The Projucer can then be used to create new JUCE projects, view tutorials and run examples. | |||
It is also possible to include the JUCE modules source code in an existing project directly, | |||
or build them into a static or dynamic library which can be linked into a project. | |||
For further help getting started, please refer to the JUCE | |||
[documentation](https://juce.com/learn/documentation) and | |||
[tutorials](https://juce.com/learn/tutorials). | |||
### CMake | |||
Version 3.15 or higher is required. To use CMake, you will need to install it, | |||
either from your system package manager or from the [official download | |||
page](https://cmake.org/download/). For comprehensive documentation on JUCE's | |||
CMake API, see the [JUCE CMake documentation](/docs/CMake%20API.md). For | |||
examples which may be useful as starting points for new CMake projects, see the | |||
[CMake examples directory](/examples/CMake). | |||
#### Building Examples | |||
To use CMake to build the examples and extras bundled with JUCE, simply clone | |||
JUCE and then run the following commands, replacing "DemoRunner" with the name | |||
of the target you wish to build. | |||
cd /path/to/JUCE | |||
cmake . -B cmake-build -DJUCE_BUILD_EXAMPLES=ON -DJUCE_BUILD_EXTRAS=ON | |||
cmake --build cmake-build --target DemoRunner | |||
## Minimum System Requirements | |||
#### Building JUCE Projects | |||
- __macOS/iOS__: Xcode 9.2 (macOS 10.12.6) | |||
- __Windows__: Windows 8.1 and Visual Studio 2015 Update 3 64-bit | |||
- __Linux__: g++ 5.0 or Clang 3.4 (for a full list of dependencies, see | |||
[here](/docs/Linux%20Dependencies.md)). | |||
- __Android__: Android Studio on Windows, macOS or Linux | |||
#### Deployment Targets | |||
- __macOS__: macOS 10.7 | |||
- __Windows__: Windows Vista | |||
- __Linux__: Mainstream Linux distributions | |||
- __iOS__: iOS 9.0 | |||
- __Android__: Jelly Bean (API 16) | |||

channel set. It is a collection of values from the AudioChannelSet::ChannelType | |||

The documentation below lists which AudioChannelSet corresponds to which native | |||
layouts used by AAX, VST2/VST3 and CoreAudio/AU. The layout tags in CoreAudio | |||
are particularly confusing. For example, the layout which is labeled as "7.1 SDDS" | |||
in Logic Pro, corresponds to CoreAudio/AU's kAudioChannelLayoutTag_DTS_7_0 tag, whereas | |||
AAX's DTS 7.1 Layout corresponds to CoreAudio/AU's | |||
kAudioChannelLayoutTag_MPEG_7_1_A format, etc. Please do not use the CoreAudio tag | |||
as an indication to the actual layout of the speakers. | |||

/** | |||
This class represents an instrument handling MPE. | |||
It has an MPE zone layout and maintains a state of currently | |||
active (playing) notes and the values of their dimensions of expression. | |||
You can trigger and modulate notes: | |||
- by passing MIDI messages with the method processNextMidiEvent; | |||
- by directly calling the methods noteOn, noteOff etc. | |||
The class implements the channel and note management logic specified in | |||
MPE. If you pass it a message, it will know what notes on what | |||
channels (if any) should be affected by that message. | |||
The class has a Listener class that can be used to react to note and | |||
state changes and trigger some functionality for your application. | |||
For example, you can use this class to write an MPE visualiser. | |||
If you want to write a real-time audio synth with MPE functionality, | |||
you should instead use the classes MPESynthesiserBase, which adds | |||
the ability to render audio and to manage voices. | |||

/** | |||
Base class for an MPE-compatible musical device that can play sounds. | |||
This class extends MPESynthesiserBase by adding the concept of voices, | |||
each of which can play a sound triggered by a MPENote that can be modulated | |||
by MPE dimensions like pressure, pitchbend, and timbre, while the note is | |||
sounding. | |||
To create a synthesiser, you'll need to create a subclass of MPESynthesiserVoice | |||
which can play back one of these sounds at a time. | |||
Then you can use the addVoice() methods to give the synthesiser a set of voices | |||
it can use to play notes. If you only give it one voice it will be monophonic - | |||
the more voices it has, the more polyphony it'll have available. | |||
Then repeatedly call the renderNextBlock() method to produce the audio (inherited | |||
from MPESynthesiserBase). The voices will be started, stopped, and modulated | |||
automatically, based on the MPE/MIDI messages that the synthesiser receives. | |||
Before rendering, be sure to call the setCurrentPlaybackSampleRate() to tell it | |||
what the target playback rate is. This value is passed on to the voices so that | |||
they can pitch their output correctly. | |||

sub-blocks that are rendered with multiple calls to renderVoices(). | |||
Obviously in a pathological case where there are midi messages on every sample, then | |||
renderVoices() could be called once per sample and lead to poor performance, so this | |||
setting allows you to set a lower limit on the block size. | |||

decrease this value for your synth. | |||
