Alesis QuadraSynth Plus Aftertouch (-99 to 99)

Editing Programs: Chapter 6
QuadraSynth Plus Piano Reference Manual 100
Wheel is moved up, and lowers the level when moved down.
Negative settings of this parameter will decrease the output level
of the PLFO as the Mod Wheel is raised. Since the output level of
the PLFO 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 PLFO 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 vibrato from the
PLFO.
Aftertouch (-99 to 99)
This is the modulation amount of Aftertouch over the Pitch
LFO’s Level. A positive value raises the level as more Aftertouch
is applied. A negative value will lower the amount of PLFO level
as more Aftertouch is applied.
