I'm another soon-to-be FCP-to-PPro switcher. Have CS5.5 and for the life of me can't find anywhere in Audition where the control surface can be activated. I have the iPad app AC-7 Core, which uses Mackie emulation, and am using it successfully in FCP and STP, but would like to use it in Audition as well (it has a mode for Audition, so obviously it's meant to work there). Yet it doesn't respond when I'm in the Audition app, which usually means I have to activate a command somewhere in the program for it. Any suggestions? Thanks!
