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

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 maintans 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 with the three callbacks MPENoteAdded, | |||
MPENoteChanged, and MPENoteFinished. Implement such a | |||
Listener class to react to note changes and trigger some functionality for | |||
your application that depends on the MPE note state. | |||
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. | |||

Base class for a musical device that can play sounds. | |||
To create a synthesiser, you'll need to create a subclass of SynthesiserSound | |||
to describe each sound available to your synth, and a subclass of SynthesiserVoice | |||
which can play back one of these sounds. | |||
Then you can use the addVoice() and addSound() methods to give the synthesiser a | |||
set of sounds, and a set of voices it can use to play them. 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. Any midi | |||
events that go in will be scanned for note on/off messages, and these are used to | |||
start and stop the voices playing the appropriate sounds. | |||
While it's playing, you can also cause notes to be triggered by calling the noteOn(), | |||
noteOff() and other controller methods. | |||
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. | |||
