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 sets the amount of time it takes the LFO to fade in from no modulation to
maximum modulation. 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 more slowly 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 145.
Level (00 to 99) Page 5
This is the base output level of the Amp LFO. If you want to have a constant value of
tremolo, even without using the Mod Wheel or Aftertouch, set Level above 00. The
Mod Wheel and Aftertouch can add to or subtract from this base level. Example: If
Level is set to 10 and the Mod Wheel parameter (see next paragraph) is set to 10,
there will always be some tremolo, and raising the Mod Wheel will add more
tremolo. On the other hand, if the Mod Wheel parameter is set to -10, raising the Mod
Wheel to the top will cancel out all tremolo.
Mod Wheel Depth (-99 to 99) Page 6
This parameter sets how much the Mod Wheel will increase or decrease the
Amplitude 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 Amp LFO as the Mod Wheel is raised.
Since the output level of the Amp LFO cannot be less than zero, a negative setting of
the Mod Wheel parameter will have no effect unless there is Amplitude LFO already
occurring because of some other factor like the Level parameter (see the previous
paragraph) or Aftertouch (see the next paragraph).
Aftertouch Depth (-99 to 99) Page 7
This parameter sets how much the Aftertouch will increase or decrease the
Amplitude LFO’s Level. A positive value raises the level as more Aftertouch is
applied. A negative value will lower the amount of Amp LFO level as more
Aftertouch is applied.
