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.
