Mod Wheel (-99 to 99)
This parameter sets how much the Mod Wheel will increase or
decrease the Filter LFO’s Level. A positive value raises the level
when the Mod Wheel is moved up, and lowers the level when
moved down. Negative settings of this parameter will decrease
the output level of the FLFO as the Mod Wheel is raised. Since
the output level of the FLFO cannot be less than zero, a negative
setting of the Mod Wheel parameter will have no effect unless
either the Aftertouch or the Level is set to raise the FLFO output.
If both the Level and Aftertouch are set to 00, and the Mod
Wheel parameter is set to -99, the Mod Wheel will have no effect
on the tremolo from the FLFO.

Aftertouch (-99 to 99)

This is the modulation amount of Aftertouch over the Filter
LFO’s Level. A positive value raises the level as more Aftertouch
is applied. A negative value will lower the amount of FLFO level
as more Aftertouch is applied.
Amp LFO

Amp LFO (Page 1)

The Amp LFO is usually used to add tremolo to a sound.
J
The Amp LFO variables will have an effect only if the AMP LFO
DEPTH (in the AMP function) is set to a value other than 0 , or, if
Amp LFO is a source in the MOD function.

Wave (8 choices)

The waveform determines the shape of the LFO. Use Quad Knob
[1] to select either Sine, Triangle, Square, Up Sawtooth, Down
Sawtooth, Random+-, Noise or Random+. See the diagram in the
Wave section of the PLFO description on page 67.

Speed (00 to 99)

Quad Knob [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)
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.

Trigger (Mono, Poly, Key Mono, Key Poly)

The Trigger parameter determines how the LFO should be
triggered, or started. There are four possible settings: Mono,
