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 (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.
J
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
