I would like to use the PodGo Wireless as an audio interface to play my keyboards from Apple Mainstage while having the processed Guitar go to an onstage amp. I'm wondering if the MAIN OUTS can be computer playback without the guitar, and then hook up to my amp from AMP OUT like its a pedal board. It seems like a basic question but I can't zero in on the exact answer. I see a lotta hook up diagrams for Reamping in recording, which I admit is cool, but I just want to send my keyboards to the PA and simultaneously play out of a guitar amp. By the way, I currently use Helix native in MainStage for amps (no cabs) and effects and send that from my MOTU interface through an impedance matching transformer to a 71 bandmaster in a twin cab with 2 vintage 30s and it sounds really, incredibly great. I'm thinking this could be a way to condense the set up and have wireless too. Thanks!
