PITCH LFO

The Pitch LFO function is most often used to apply vibrato to a sound.

The following Pitch LFO variables will make a difference in the sound only if the PITCH LFO DEPTH (on Page 6 of the PITCH function) is set to a value other than 0, or, if the Pitch LFO is a source in the MOD function.

Shape (8 choices)

Page 1

The waveform shape determines the shape of the LFO. Select either Sine, Triangle, Square, Up Saw, Down Saw, Random+-, Noise or Random+. Note that the two Sawtooth waves and the Random+ wave are unipolar and the rest are bipolar:

Speed (00 to 99)

Page 2

Controls the speed or rate of the LFO. For fast modulation, increase this value. For slower modulation, decrease this value.

Delay (00 to 99)

Page 3

This is the amount of time that is to occur before the LFO fades in. Sometimes, it is desirable to have modulation come in a moment or two after a note has been played, rather than starting instantly. The higher the value, the slower the LFO fades in.
