Wow, that's impressive Gswitz. I don't know if I'd be using it for all the way you've done it, but mostly want it to control my amp sims (TH3, A4, Bias Fx etc.. ). Is the app you're taking about is something you developed or is it some sort of chip that needs to installed? I briefly looked at the Uno app as well...
Programming it seems to be the biggest complaint (from the little I've read). I'm not much of a midi guy, so hopefully won't have to spend an unreasonable amount of time trying to program it.
