Hi there,

Was looking at getting a GR-20 for a smaller portable rig and my pedal board won't fit an Ax8/GR20 and an expression pedal on it....
So I had the idea is it possible to use the GR20 expression pedal to act as an expression pedal via midi into the AX8 to control wah/volume/mix etc

It mentions pg 29 in the manual under midi messages transmitted by the GR20
Expression pedal
CCno7 (volume) or number 4 (foot type) is transmitted according to the movements of pedal.

Would this work?
thanks!

Yes it should work,
I recall using the GR-20 midi connected out to a GT-10B, and having to disable the GR-20 EXP midi out as it controlled the GT patch volume.
