The Controller parameters determine how the various
performance controllers affect the sound. The four control-
lers are: MODULATION wheel, PITCH wheel
(PitchBend), After Touch (AfterToch), and Foot Controller
(FootCntrl).
These controllers can be used to change three different
aspects of the sound: volume (Amp), pitch (Pch), or
timbre/filter (Fltr). The Bias parameters (shown as dials in
the display) control the depth of the effect. The Modula-
tion parameters (shown as sliders below the Bias parameter
dials) control the modulation — creating a wavering
vibrato/wah type of effect. Each controller has the same
five parameters, and they are explained together below.
Amplitude EG Bias Depth (Amp dial)
Range: -64 (-100%) — +63 (+100%)
This determines how the controller affects the Amplitude or
volume of the sound. For positive values, the volume level
increases as the controller is moved toward the maximum.
For negative values, the effect is reversed: moving the
controller to the maximum results in a decrease in volume.
Pitch Bias Depth (Pch dial)
Range: -24 — +24 semitones
This determines how the controller affects the pitch of the
sound. For positive values, the pitch is raised as the
controller is moved toward the maximum. For negative
values, the effect is reversed: moving the controller to the
maximum results in a lowering of the pitch.

Pitch Modulation Depth (Pch slider)
Range: 0 — 127
This determines how widely the pitch is modulated by the
LFO (low frequency oscillator), producing a vibrato effect.
The higher the value, the deeper the pitch modulation, and
hence, the more pronounced the vibrato effect.
Filter Cutoff Bias (Fltr dial)
Range: -64 (-100%) — +63 (+100%)
This determines how the controller changes the filter
setting, which affects the timbre or tonal quality of the
sound. For positive values, the tone becomes brighter as
the controller is moved toward the maximum. For negative
values, the effect is reversed: moving the controller to the
maximum results in a warmer, more round sound.
Filter Modulation Depth (Fltr slider)
Range: 0 — 127
This determines how widely the filter is modulated by the
LFO (low frequency oscillator), producing a regular "wah-
wah" filter sweep effect. The higher the value, the deeper
the filter modulation, and hence, the more pronounced the
filter sweep effect.
NOTE: The default settings for the above parameters are as
follows:
• MODULATION wheel Pitch Modulation Depth: +10
• PITCH wheel Pitch Bias Depth: +2
• All other parameters are set to a default value of 0.
