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:
SINE
TRIANGLE
SQUARE
UP SAW
DOWN SAW
RANDOM+-
NOISE
RANDOM+
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.
