Virtual expression pedal system (Internal
Pedal / Wave Pedal)
By assigning a desired parameter to the virtual expression pedal, you can
produce an eect as though you were operating a physical expression
pedal to change the volume or tone quality in real time.
The virtual expression pedal system provides the following two types of
functions, and you can use the SOURCE setting for ASSIGN 1–8 to choose
the desired type.
* If you want to use the internal pedal or wave pedal, set the ASSIGN
parameter SOURCE MODE to “MOMENT.”
Internal pedal
If SOURCE is set to “INT PEDAL,” the virtual expression pedal will begin
operating when started by the specied trigger (INT PDL TRIGGER),
modifying the parameter specied by TARGET.
The value changes in a curve
When the trigger occurs
Wave pedal
If SOURCE is set to “WAVE PEDAL,” the virtual expression pedal will
cyclically modify the parameter specied by TARGET in a xed wave form.
Always changes in a xed curve regardless of the actual pedal
Input Level
Input level
The parameter set as the target changes in response to the input level.
MEMO
If you want to adjust the input sensitivity, set the INPUT SENS.
About the Range of a Target’s Change
The value of the parameter selected as the target changes within
the range dened by “Min” and “Max,” as set on the GT-100.
When using an external footswitch, or other controller that acts as
an on/o switch, “Min” is selected with O (CLOSED), and “Max” is
selected with On (OPEN).
When using an external expression pedal or other controller that
generates a consecutive change in the value, the value of the
setting changes accordingly, within the range set by the minimum
and maximum values. Also, when the target is of an on/o type,
the median value of the received data is used as the dividing line in
determining whether to switch it on or o.

* The range that can be selected changes according to the target
setting.
* When the “minimum” is set to a higher value than the “maximum,”
the change in the parameter is reversed.
* “The values of settings can change if the target is changed after
the “minimum” and “maximum” settings have been made. If
you’ve changed the target, be sure to recheck the “minimum” and
“maximum” settings.
