eliminate types. Some voices use very little
filter processing at all. Changing the filter
settings may not produce a particularly notice-
able effect. For detailed filter parameter pro-
gramming use the VL70-m Expert Editor
software (page 25).
17: FilCtrlDpt
 (VOICE mode only)
• Filter Control Depth
• Settings: -127 … +127
Sets the amount of variation produced by the
controller assigned to dynamic filter. The higher
the value the greater the variation. Positive values
cause an increase in filter cutoff frequency in
response to higher controller values (e.g. increased
breath pressure or higher modulation wheel
position), while minus values cause a decrease in
filter cutoff frequency in response to higher
controller values. The “Depth” setting is reflected
in the graph at the bottom of the display — the
horizontal axis represents the controller value and
the vertical axis represents filter cutoff frequency.
The effect of the filter may be barely noticeable
on some voices. In some cases it may be
necessary to lower the cutoff frequency to
produce the desired effect.
18: Fil Curve
 (VOICE mode only)
• Filter Curve
• Settings: -16 … +16
Determines the relationship between the controller
value and dynamic filter cutoff frequency. When
set to “+00” the relationship is linear. That is, a
change in the controller value produces a corre-
sponding change in frequency. As the curve value
increases the lower end of the controller range has
relatively little effect on the sound while higher
controller values produce more dramatic changes.
Negative curve values have the opposite effect: the
sound changes dramatically at low controller
values while higher values produce relatively little
effect. The “Curve” setting is reflected in the graph
at the bottom of the display — the horizontal axis
represents the controller value and the vertical axis
represents filter cutoff frequency.

Amplitude
19: Amp CC No.
 (VOICE mode only)
• Amplitude Control Change Number
• Settings: off… 95, AT, VEL, PB
Unlike pressure, “Amplitude” controls the volume
of the sound without varying timbre or pitch. The
“Amp CC No.” parameter specifies the controller
to be used for amplitude control. When set to “off”
maximum volume is produced at all times.
The “AmpCtrlDpt” parameter, below, must be
set to an appropriate value (higher than “+01”
or lower than “-01”) for amplitude control to
have any effect.
20: AmpCtrlDpt
 (VOICE mode only)
• Amplitude Control Depth
• Settings: -127 … +127
Sets the amount of variation produced by the
controller assigned to amplitude. The higher the
value the greater the variation. Positive values
cause an increase in amplitude in response to
higher controller values (e.g. increased breath
