My setup : Computer sends program change to a master footswitcher (Decibel 11- Switch Dr). Then the Switch Dr sends program changes to a HX effects and another unit (TC nova drive).
When I hit a preset on the Switch Dr, everything work perfectly. Hx changes to the right patch. But, if the Switcher receives a program change from the computer, then, everything still react accordingly except the Helix that now switch to the wrong patch.
Now, I had a M13 in my original setup and everything was fine. Once I've upgraded from a M13 to a HX effects, I can't use a computer to change programs.
I did numerous shows with that setup and the only difference is the HX effects.
Any idea?
