Hi Jeff,
It's working fine, actually. I have run the G system with both the Dyne and my MR, and the switching works well. No lag that I can detect.
Of course I just couldn't make it simple... I have the G system controlling the Ground Control Pro via MIDI, and both the G system and GCP/GCX controlling pedals via their loops. Everything plays together pretty well, but it's too much junk on the floor, even with all the pedals in a rack.
I am stuck with this: Neither the GCP nor the G System has all the functions I want. I also have too many pedals for either. I really want a button to control everything, so I don't have to change presets to get different sounds. That aspect means I need lots of buttons on the floor. I can either have the GCP/GCX control a bunch of pedals, or I can put the pedals on the floor and control them directly, combined with teh Gsystem and either way it takes up about the same amount of floor space. I can also have the pedals on the floor along with the GCP, and ditch the G system, and again it's about the same amount of junk on the floor.
I originally wanted some basic automation, along with the flexibility of the pedals. I think that the GCP/GCX is the more likely final solution. The G System just doesn't have enough buttons for pedal control.
I'd be happier with EITHER the GCP or the G System if they had 4-5 more buttons for a bit more flexibility.
Right now I'm taking a step back to see what I am willing to give up in order to simplify the setup.
