Functions

calculateJumpAm void calculateJumpAm(int sampleRate, float lfoOut): Calculates jump amount for the sample.
decodeMore void decodeMore(SampleAssignment sa, Sample slmp): Decodes one more block worth of samples, depending on internal state.
reset void reset(): Resets all internal states.
setADSR void setADSR(int sampleRate): Undocumented in source. Be warned that the author may not have intended to support it.
setShpVals void setShpVals(float vel): Recalculates shape params.
