Detailed Description

template<class Precision, class VoiceClass, int32 numChannels, int32 maxVoices, class GlobalParameterStorage>
class Steinberg::Vst::VoiceProcessorImplementation< Precision, VoiceClass, numChannels, maxVoices, GlobalParameterStorage >

A Simple Voice Processor Implementation supporting note expression events.

Parameters

Precision	must be either float or double
VoiceClass	the voice class
numChannels	number of channels
maxVoices	number of maximum voices
GlobalParameterStorage	a class holding global parameters

The VoiceClass must implement the following methods:

int32 getNoteId () const;
void setGlobalParameterStorage (GlobalParameterStorage* globalParameters);
void setSampleRate (ParamValue sampleRate);
void setNoteExpressionValue (int32 index, ParamValue value);
void noteOn (int32 pitch, ParamValue velocity, float tuning, int32 sampleOffset, int32 noteId);
void noteOff (ParamValue velocity, int32 sampleOffset);
bool process (SamplePrecision* outputBuffers[numChannels], int32 numSamples);
void reset ()

See Steinberg::Vst::VoiceBase for an example base class.

This implementation does not support advanced features like voice stealing when maxVoices is reached, etc ...
