Amp LFO (Page 2)

Level (00 to 99)

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 will add or subtract from this base level. Example: If Level is set to 10 and the Mod Wheel parameter 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 (-99 to 99)

This is the modulation amount of the Mod Wheel over the Amp 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 ALFO as the Mod Wheel is raised. Since the output level of the ALFO 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 ALFO 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 ALFO.

Aftertouch (-99 to 99)

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

Pitch Envelope

Pitch Envelope (Page 1)

Pitch Envelope can lead to dramatic effects, since it can cause the pitch of a single key to change drastically over time. It’s typically used in special-effect synthesizer programs, but it may also be used more subtly in an acoustic program to simulate the characteristic of some instruments to go sharp on the initial attack, especially when played hard.

The following Pitch Envelope variables will have an effect only if the PITCH ENVELOPE DEPTH (on Page 2 of the PITCH function) is set to a value other than 0, or, if Pitch Envelope is a source in the MOD function.

Attack (00 to 99)

This is the amount of time the envelope will take until it reaches its maximum output level. Setting the Attack to 0 will make the
