Korg AX3000G User Manual

40

The AX3000G provides a built-in expression pedal that you can use to control not 
only wah or volume, but a wide variety of effect parameters. For each program, 
you can specify which effect will be controlled, and how. The effect to which the 
expression pedal is assigned can be switched on/off by advancing the expression 
pedal all the way forward to operate the switch located under the pedal. The 
expression pedal LED will be lit or dark to indicate the on/off status of the effect.

NOTE: If you’re using the expression pedal as a volume pedal, the LED will light 
amber. In this case, the switch located under the pedal has no effect. If you’re using 
the expression pedal to control another parameter, the LED will light green.

HINT: If you’ve assigned a parameter to the expression pedal, operating the pedal 
has the same result as using the knob to edit the program. This means that when 
you operate the pedal, the EDIT icon will light. When you write the program, it will 
be written with the sound as currently specified by the position of the pedal. How-
ever if the expression target is “--OFF--,” “VOLUME,” “M/PITCH,” “D/INPUT,” or “R/
INPUT,” the program will not be edited by the pedal.

Here’s a very easy and convenient way to set the expression target.

As an example, use the MODULATION selector to choose PITCH SHIFTER. So 
that the effect will be easy to hear, we’ll initialize the PITCH SHIFTER. If PITCH 
SHIFTER is already selected, turn the selector to choose a different effect, and 
then re-select PITCH SHIFTER.

When you’re editing PITCH SHIFTER, turn value knob 1 or use the √

 buttons 

to make the name display show PITCH; the 

 icon will appear. If in this state 

you press and hold (for one second) the EXP/CTL button, the name display will 
indicate COMPLETE. The PITCH parameter has now been assigned to the 
expression pedal, letting you control the amount of PITCH SHIFT. At this time, the 

 icon will appear in the LCD display. If you want to make more detailed set-

tings, you can press the EXP/CTL button and set the minimum value (“EXP MIN,” 
value knob 2) and maximum value (“EXP MAX,” value knob 3) of the target range.

NOTE: If you change the effect type of a parameter that is assigned to the expres-
sion target (i.e., to be controlled by the expression pedal), the target will be initial-
ized to a setting of “--OFF--”. (However, “D/INPUT”, “R/INPUT” are exceptions.)

HINT: If you’ve selected “VOX WAH” as the pre-effect type, “P/MANUAL” (wah posi-
tion) is automatically assigned to the expression pedal. In this case if you change 
the pre-effect back to another type without performing any other operation, the Tar-
get, Min, and Max settings will automatically revert to their previous state. However 
if a pre-effect parameter was the target, it will be set to “--OFF--” rather than revert 
to its previous state.
