The app update disabled my older iPad without warning, which rendered the mixer entirely useless and threatened the entire show. To show up at a gig and have the app that controls your mixer simply crash is a performer's worst nightmare. It's incredible to me that Behringer has so little regard for working musicians who depend on their equipment for our living. I had noticed the issue with the app in demo mode before the unit arrived, had hoped it would be better when actually attached to hardware! You may also use the application in demo mode for offline show preparation, when no mixer is available. Switching to 'Advanced' mode offers full access to many more parameters of Sends, Gate and Compressor sections, when needed.

The user interface is providing access to mixing 18 input channels to 12 buses and editing 4 internal stereo effects processors, with highest professional audio quality, yet hiding away most of the underlying complexity.
