Zoom GFX-8 User Manual

Listening to Patches (Play Mode Operation)
1. To switch the effect used in the DRIVE, MOD, or
DLY/REV module, operate the selector and key for the
respective module.
When the effect is switched, the name of the new effect is shown on
the display for about 2 seconds. The EDITED mark (.) in the
GROUP/BANK indicator lights up. This indicates that an effect
parameter of this patch has been edited. The mark disappears when the
setting is changed back to the original setting.
While only the effect group was switched, the previous
effect is still active. The change does not occur until the
selector for the respective module is operated. Therefore
the selector position and the actual effect may differ
during this interval.
2. To adjust a major parameter of each module, operate
the following knobs.
When one of the above knobs is moved, the display shows the
parameter name and the GROUP/BANK indicator shows the
parameter value for about 2 seconds.
Which parameter is assigned to the GAIN knob, PARM
SELECT/ADJUST knob, and PARM VALUE/ADJUST knob
depends on which effect is selected for that module (
see page 19 - 29).
• Trying to change effects or parameters which are set to
OFF in the current module has no effect. In this case,
the indication "OFF" is shown on the display.
• All changes made with the easy edit function are
temporary. Settings revert to the original condition when
the patch is switched. When wishing to keep the
changes, you must store the patch (see page 18).

However, it is also possible to switch effects in modules and change major effect parameters in play mode. This is called the easy
edit function.
