Description

Implementation of AudioBus virtual. We will make it pure here, because all virtual instruments must handle this themselves. virtual void Prepare(float sampleRateHz, uint32 numChannels, uint32 maxSamples, bool allocateBuffer = true) override = 0; Any subclass of VirtualInstrument will also have to implement the AudioBus pure virtual function... virtual void Process(AudioBuffer& output) = 0;

virtual void CallPreProcessCallbacks  
(  
    int32 NumSamples,  
    float SampleRateHz,  
    int32 SliceIndex,  
    int32 Subslice,  
    bool LastSubslice  
)
