| 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. | |||
