Just tested mine again (FW 1.12, btw) and I keep most of my fx off and then turn them on. When I do this, the GCP works perfectly. BUT, if I have something on like slot A and hit the footswitch to turn it off, it seems like the first time tells it to turn 'on' again, so it acts like it doesn't see it, second click turns it off. I also tried with XMIT on patch change or whatever it's called and normal setting, both behave the same. I hardly ever have fx turned on my patches to begin with, so I never really noticed it. If I did have something on I would need to turn off later, I'd tap it one time - as long as you don't change entire presets, it will remember that even if you hit other IAs and then it's a single tap. Kinda a pain in the ass though.
I haven't seen it act otherwise and tested the crap out of it this morning - it's a 100% thing. I have mine set to channel 1 on the footswitch and kemper, and channel 2 is a TC nova system.

I guess I could try it like that but my presets always have delay on. It's the others that are off all the time on each preset that seems to be giving me the problems. For example, I have a flanger on switch IA6. It's off in all my presets. But when I step on it to engage it, it will turn on in the Kemper (stomp D) 9 out of 10 times. It's that 1 time where it doesn't that is very random.
Happy birthday BTW!
