Detailed Description

A monophonic/polyphonic synthesiser base class which can be supplied with a custom voice.

Supports different kinds of after touch, pitch bend, velocity and after touch curves, unison (currently monophonic mode only)

SetKeyToPitchFn()

void MidiSynth::SetKeyToPitchFn ( const std::function< float(int)> &  fn )

inline

Set this function to something other than the default if you need to implement a tuning table for microtonal support.

Parameters

fn	A function taking an integer key value and returning a double-precision pitch value, where 0.5 = 220Hz, 1.0 = 440 Hz, 2.0 = 880 Hz ("1v / octave").

SetPitchBendRange()

void MidiSynth::SetPitchBendRange ( int  pitchBendRange )

inline

Set the pitch bend range for non-MPE mode.

Definition at line 74 of file MidiSynth.h.

SetPolyMode()

void MidiSynth::SetPolyMode ( VoiceAllocator::EPolyMode  mode )

inline

Definition at line 87 of file MidiSynth.h.

SetSampleRateAndBlockSize()

void MidiSynth::SetSampleRateAndBlockSize	(	double	sampleRate,
		int	blockSize
	)

Definition at line 477 of file MidiSynth.cpp.

SetVoicesActive()

void MidiSynth::SetVoicesActive ( bool  active )

inline

If you are using this class in a non-traditional mode of polyphony (e.g.to stack loads of voices) you might want to manually SetVoicesActive() usually this would happen when you trigger notes.

Parameters

active

should the class report that voices are active
