Peter, I know you're still on a break, so i do not expect a response anytime soon just wanted to throw this out there. I'm not sure if this is even something possible, so take it with a grain of salt. Would it be possible to use something like a Beringer control surface (Daw/midi controller) with stage traxxs to have a physical interface for the mixer view in the app? I typically give the iPad to our sound guy at the church, and he does not prefer using an iPad to control the tracks and would prefer a physical interface to control. With the new mixer view in ST4 I'm not sure if that is possible to do/program, but just thought i would offer the idea. I guess it would depend on whether I'm the only one who would use this or if others would use it as well.
