Glad you have solved your problem, must have been very frustrating when you play that much.
I don't have problems with any output channels. when I loose outputs it's after the INT.PHASE error message apears. Then the Exit/USB button lights. There can be weeks without that happens. I've had more problems with Left Sound that drops out. I have checked all connectors many times. Last week I used the Audya in my band. (not using styles) worked perfect, played fine all week Yesterday's gig I used my Korg, I really missed the Audya sounds and the keybed. If I can get myself to trust the Audya I will probably use it in the band all the time.
