The problem I am having is telling my GR-33 to change sounds from the Godin ACS guitar, this used to work in the past, so I think I may have changed a setting somewhere.

The Godin ACS comes with two buttons inbuilt that originally used to change the sounds up and down, depending on which one you pressed.

I know the problem is not with the godin sending a message as when I press either of the buttons a light in the "Group Bank Number" flashes.

The Group Bank Number when I initially turn the machine on says:

A11

The next window says Jazz Scat.

When I press the button on the Godin a light comes on between the A and the 11 and after the 11. As I press the button those two lights appear, I can keep a rythm going on those two lights so it is recieving some sort of signal.

It used to change the Group Bank number and thus change the sound simply from pressing either of these buttons.

It doesn't anymore.

Is there a way of reseting it back, or is there a known issue where if you change certain parameters that function stops working?

Any help would be nice.
