1.
While the GFX-4 is in program mode, select the
patch you want to edit.
The module LEDs show the status of each module within
that patch.
COMP/OD/ENV, DRIVE, and EQUALIZER share
the FX pedal 1 which can be assigned to any of
these modules. However, when the assigned
module is off (module LED lit in green), operating
the FX pedal 1 only switches module on or off.
• The MODULATION and PEDAL modules share
the FX pedal 2. Normally, the FX pedal 2
controls the MODULATION module, but when
the PEDAL module is selected as operation
target, the FX pedal 2 controls the PEDAL
module. The PEDAL module LED is flashing.
• The FX pedal 3 is permanently assigned to the
DELAY/REVERB module. It always controls the
DELAY/REVERB module.
2.
Press one of the module keys (COMP/OD/ENV,
DRIVE, EQUALIZER, PEDAL, MODULATION,
DELAY/REVERB) to select the target module.
The LED of the selected module flashes, and the display
shows the name of the effect type selected for that module
(if the module is on), or "-OFF--" (if the module is off).
3.
To toggle the selected module between on and
off, press the module key of the corresponding
FX panel again.
You can also switch between on and off by
pressing the module key of the module whose
LED is flashing.
The PEDAL module serves for making expression
pedal settings. It is not a regular effect and can
therefore not be turned off.
4.
To switch the effect type of the selected
module, use the TYPE DOWN/UP keys on the
corresponding FX panel.
For example, when switching a module from on to off,
the module LED changes from flashing red to flashing
green.
The assignment of FX panels 1 - 3 to the modules is as
follows.
• FX panel 1:
COMP/OD/ENV, DRIVE,
EQUALIZER module
• FX panel 2:
PEDAL, MODULATION module
• FX panel 3:
DELAY/REVERB module
The name of the currently selected effect type is shown
on the display.
