Why can't I find this information anywhere??? I just need to know how many U it is??? IS it weird they don't have a full blown version of the application for use on a MAC or PC? I would like to try and bring a Surface Pro to shows and control this via wifi while at the SAME TIME recording via USB. Impossible? The Mackie DL1608 has the Master Fader application that can let me control the DL1608 / iPad from my phone. Anything in the works for this with Behringer?
