Field Detail

amplitude

public UnitInputPort amplitude

frequency

public UnitInputPort frequency

pitchModulation

public UnitInputPort pitchModulation

This scales the frequency value. You can use this to modulate a group of instruments using a shared LFO and they will stay in tune.

cutoff

public UnitInputPort cutoff

cutoffRange

public UnitInputPort cutoffRange

Q

public UnitInputPort Q

Method Detail

noteOff

public void noteOff(TimeStamp timeStamp)

Specified by:

noteOff in interface UnitVoice

noteOn

public void noteOn(double freq,
                   double ampl,
                   TimeStamp timeStamp)

Description copied from interface: UnitVoice

Play whatever you consider to be a note on this voice. Do not be constrained by traditional definitions of notes or music.

Specified by:

noteOn in interface UnitVoice

Parameters:

freq - in Hz related to the perceived pitch of the note.

ampl - generally between 0.0 and 1.0

timeStamp - when to play the note
