Mod Wheel Depth (-99 to 99) Page 6
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 Filter LFO as the Mod Wheel is raised. Since the output level of
the Filter LFO 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 Filter LFO 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 Filter LFO.
Aftertouch Depth (-99 to 99) Page 7
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 Filter LFO level as more Aftertouch is applied.
AMP LFO
The Amp LFO function (press [8]) 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, page 3) is set to a value other than 0 , or, if Amp LFO is a source in the
MOD function.
Wave (8 choices) Page 1
The waveform determines the shape of the LFO. Select either Sine, Triangle, Square,
Up Sawtooth, Down Sawtooth, Random+-, Noise or Random+. See the diagram in
the Wave section of the Pitch LFO description on page 76.
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.
Trigger (Mono, Poly, Key Mono, Key Poly) Page 4
The Trigger parameter determines how the LFO should be triggered, or started. There
are four possible settings: Mono, Poly, Key Mono and Key Poly. A description of these
settings is found in the Trigger section of the Pitch LFO description on page 77.
