I don't think you have studied the system enough if you cannot adjust any real paramaters on stage without a phone or tablet. I set all of my amp and cabinet settings off stage with devices but can adjust volume, eq reverb and FX mix with the knobs, then hold down the patch button with foot for a couple of seconds til it blinks. boom! its saved to the system.
It's designed to fine tune your settings with the knobs in a tight spot. Sure I have had a few bluetooth connection issues, nothing a power cycle wouldn't fix.
Id like to think the way I have it set up, as long as the physical knobs still work on the unit- I'm good. I don't want to spend endless years tweaking parameters, I wanna rock
