That would be so awesome. It's the ONLY feature I would like them to add and it's the only reason I will continue to use my QSC when mixing from on stage while playing.
When running from FOH, I run 3 to 4 iPads so I can very quickly access different features. I run 2 of them with main fader views of different input groups. The 3rd one I like to keep for monitor adjustments or DCA groups, and the 4th I run with my delay sends on fader view as I like to play with the delays a lot so I can ring out some words and phrases easily with a long delay decay when it's appropriate. It's still a tiny footprint I take up and I can pick up my whole station and move anywhere in the venue if I'm in the way or need a better view. I can also grab one of them and walk around the venue to tweak things. I know it's a bit of overkill on the iPads, but, I have them, I might as well use them. Plus, it looks cool as hell to have a little army of iPads running the show. I had so many people come up to me at the show last weekend and marvel at my little Star Trek mixing station.
Eventually, I would like to look into the DC16 control surface as an addition, but looking at the NAMM videos about it, it looks like the price pint is going to be WAY too high to justify.
