I can hardly believe this happened, what bad timing too. While playing
 tonight my Mono/Poly went completely silent. Just was working fine and
 then like the cable was unplugged, no sound. Everything behaves like
 it's working, pressing a key in mono mode lights up all oscillators,
 pressing to poly mode works and I can see the individual osc's lighting
 up, but no sound, not even from the headphone jack.
 I will start combing through the messages here and try to do some
 troubleshooting in the meantime, but I'm hoping for some miracle to get
 this up and running in three days before my bands next show. More than
 half our set relies on the mono/poly, and I don't have any other
 keyboard that even comes close to sounding like this. Maybe my casio vl-
 tone, I could try that. :)
 Anyways I really am in shock, all humor aside. If anyone has any
 helpful info please shoot it my way. Thanks
