Q:	As output level of each programmed patch is uneven, I would like to keep them even.

A:	Please adjust "Patch Level" parameter for each patch to keep the output level even. You can set up total patch level.

Q:	Is it possible to turn on/off effect modules by foot pedals?

A:	GFX-4 has a function which you can assign each effect module to foot pedals and turn on/off each effect. This function is called "Manual Mode". Foot pedals of GFX-4 can be just like on/off switch of stomp box. Please refer to explanation of ﾒManual Modeﾓ in operation manual.

Q:	Effects, such as "Wah" using expression pedal, do not start.

A:	Expression pedal operates also as an on/off switch for assigned effect by stepping on. Please step on ahead more strong. Refer to "Adjusting the expression pedal" in operation manual. In case of GFX-4, you can set up the expression pedal as exchange switch for "Manual Mode to Program Mode".
