I end up plugging in my duet partners feed into he aux in on the PA4x then I mix it together until I get the mix I like coming through the PAAS
Frank - When I had the PAAS, the aux in signal did NOT feed through the main audio outs. Are you using the actual "aux" in, or feeding into the Mic input?
That was the main reason I sold my PAAS. Korg confirmed that it was not built to pass that signal through. Was I misled?
