Concerning UC Surface Features:
1. Would be nice, if uc surface had more colors for the channels and let select the channels also when I'm touching the faders.
2. Would be much more nice, if uc surface for iOS let select languages!
3. Would be super nice, if uc surface let select only 16 channel inputs for RML 16 AI.
4. Take a look to QSC Touchmix Control. In my opinion much easier to use.
