Other Functions
This section explains special functions such as varying a particular effect parameter in real time, using the hold
delay and sampler functions, and returning the patches to the factory default condition. Pedal calibration is also
explained.
Changing effects in real
time
The GFX-5 allows you to vary a particular effect
parameter in real time. For example, you could use
the expression pedal as control source and the effect
type P-WAH of the MOD module as control target.
Operating the pedal then will change the filter
frequency, resulting in a pedal wah effect.
The newly developed ARRM feature lets you use an
internally generated control waveform instead of
the expression pedal. This makes it possible to
easily create cyclic variations of an effect
parameter. If you select the control waveform
(triangle wave) as control source and the effect type
P-WAH of the MOD module as control target, you
get a cyclic wah sound even without operating the
pedal.
You can go even further. It is possible to control the
ARRM modulation depth with the expression pedal,
and to link the control waveform cycle to the
rhythm pattern.
The procedure for using the expression pedal and
ARRM feature to alter parameters in real time is
described below.
■ Selecting the control source and
control target
First, select the element (expression pedal, ARRM,
or a combination of both) to be used as control
source.
1. In play mode, select the patch.
2. Press the [CONTROL] key repeatedly to
select the control source.
With each push of the key, the source cycles
through the following settings, and the
corresponding [CONTROL] LED lights up:
PEDAL → ARRM → ARRM + PEDAL. The
meaning of each selection is explained below.
●
PEDAL
The expression pedal serves as control source, to
vary an effect parameter or the volume with your
foot.
●
ARRM
The ARRM (Auto-Repeat Real-time Modulation)
feature is active. The effect parameter is varied
cyclically, using an internally generated control
waveform.
●
ARRM + PEDAL
The ARRM feature is active, but its modulation
depth can be adjusted with the expression pedal.
3. Repeatedly press the [ASSIGN] key to
select the module to be used as control
target.
With each push of the key, the target cycles through
the following settings, and the corresponding
[ASSIGN] LED lights up: WAH → PITCH →
MOD → GAIN → REV → VOLUME →
SAMPLER.
The meaning of each selection is explained below.

●
WAH
The effect type P-WAH (pedal wah) of the MOD
module is selected as control target, and the wah
frequency (FREQ parameter) can be adjusted with
the pedal or the ARRM function. Also if another
effect type is selected for the MOD module, it will
be switched to P-WAH while this LED is lit.
● PITCH
The effect type P-PIT (pedal pitch) of the MOD
module is selected as control target, and the effect
sound pitch can be adjusted with the pedal or the
ARRM function (resulting in a pitch shift effect).
Also if another effect type is selected for the MOD
module, it will be switched to P-PIT while this LED
is lit.
●
MOD
The currently selected effect type of the MOD
module is selected as control target and can be
adjusted with the pedal or the ARRM function. The
actual parameter that is adjusted depends on the
effect type.
●
GAIN
The GAIN parameter (for some effect types the
RESONANCE/TOP parameter) of the DRIVE
module is selected as control target and can be
adjusted with the pedal or the ARRM function
(resulting in a change in distortion intensity).
●
REV
The currently selected effect type of the REV
module is selected as control target and can be
adjusted with the pedal or the ARRM function. The
actual parameter that is adjusted depends on the
effect type.
●
VOLUME
The master volume can be adjusted with the pedal
or the ARRM function.
●
SAMPLER
The built-in sampler playback volume can be
adjusted with the pedal or the ARRM function. The
sampler function can be switched on and off by
fully depressing the expression pedal.
HINT
• For information on the controlled parameter
when MOD, GAIN, or REV is selected, see
pages 31 – 34.
• If the module that was selected as control
target is currently off, it will be switched
temporarily to on.
• The control source and control target settings
are stored individually for each patch. If you
want to retain your settings, store the patch
(→ p. 19).
■ Controlling the ARRM operation
When “ARRM” or “ARRM + PEDAL” is selected
as control source, the control waveform type and
frequency can be set in edit mode.
4. Press the [EDIT/EXIT] key to activate edit
mode, and select the TOTAL module.
The ARRM function settings are part of the TOTAL
module.
5. Use the PARAMETER [ Q ]/[ W ] keys to
bring up the indication “R-WAVE” on the
display, and turn the [VALUE] dial to
select a control waveform from the
following options.
The following waveform settings are available.
6. To set the control waveform cycle, use the
PARAMETER [
Q ]/[ W ] keys to bring up
the indication “R-SYNC” on the display,
