getNextValue()

virtual bool IParameterUpdateQueue::getNextValue ( double &  _nextValue )

pure virtual

Get the sample-accurate value of the parameter at the next sample offset, determined by an internal counter Returns true if dNextValue is different than the previous value

Implemented in Steinberg::Vst::ASPiK::VSTParamUpdateQueue.

getParameterIndex()

virtual uint32_t IParameterUpdateQueue::getParameterIndex ( )

pure virtual

Get the index number associated with the parameter

Implemented in Steinberg::Vst::ASPiK::VSTParamUpdateQueue.

getValueAtOffset()

virtual bool IParameterUpdateQueue::getValueAtOffset ( long int  _sampleOffset, double  _previousValue, double &  _nextValue  )

pure virtual

Get the sample-accurate value of the parameter at the given sample offset. Pass in the last known normalized value. Returns true if dPreviousValue != dNextValue

Implemented in Steinberg::Vst::ASPiK::VSTParamUpdateQueue.
