Method Detail

reset

public void reset()

Set the LFO to default values.

setWaveform

public void setWaveform(int wave,
                        boolean retrig)

Set the LFO waveform to that which is specified (amazingly)

Parameters:

wave - The waveform ID. See above.

retrig - If true, retrigger the waveform at new note.

update

public int update(int speed,

Update the oscillator.

Parameters:

speed - The amount to advance the LFO.

newNote - If true, the waveform is retriggered if required.

Returns:

the current value between -255 and 255.
