I want to configure my 788 to simultaneously send four channels out to a quadraphonic reel to reel deck. Is there a way to do this using AUX SENDS and other monitor channels, or some other method that gets me more than 2 channels output? I could do 2 channels panned L & R at a time, but I'm afraid I'll run into synchronization problems trying to match-up the track pairs on the Akai GX 280D-ss reel to reel deck.
