▪ Use the Ramp Low/High parameters to specify the slope of the keyboard
tracking (-99…+99).

▪ Set the Intensity to A and Intensity to B parameters (-99…+99) to specify
the depth and direction of the changes applied to filters A and B.
For the range of notes between Key Low and Key High, the cutoff frequency
will change according to the keyboard location (pitch).
Modulating the Filter EG (Envelope Generator)
The filter envelope can be controlled while playing.
▪ Use the Velocity to A/B parameter (99…+99) to specify the depth and direc-
tion of the effect that velocity will have on the time-varying changes created
by the filter EG (as set on Filter > Filter EG) to control the filter A/B cutoff
frequency.
With positive (+) values, playing more strongly will cause the filter EG to pro-
duce greater changes in cutoff frequency. With negative (–) values, playing
more strongly will also cause the filter EG to produce greater changes in
cutoff frequency, but with the polarity of the EG inverted.
▪ Use the Int to A/B parameters (-99…+99) to specify the depth and direction
of the effect that the time-varying changes created by the filter EG will have
on the filter A/B cutoff frequency.
With positive (+) settings, the sound will become brighter when the EG levels
set by Filter EG Level and Time parameters are in the ‘+’ area, and darker
when they are in the ‘–’ area.
With negative (–) settings, the sound will become darker when the EG levels
set by Filter EG Level and Time parameters are in the ‘+’ area, and brighter
when they are in the ‘–’ area.
