Hi there.

I have a Boss GT-PRO and I have a problem. When I switch between the patches there seems to be a change of volume, from one patch to another.
Does anyone know how to fix this??

Don't know about the Pro specifically but with the GT-100, you just tweak the patch volume control for each patch. Some effects will add or subtract volume, (like overdrives, EQ, etc) so you have to compensate for that with patch volume.
