I know, very surprising, and I don't use the unit that much. The most troubling is that MIDI Thru doesn't work any more. I assume it requires extremely little. I did swap cables around, and simply bypassed the 7600 via a female-female MIDI adaptor in my chain, and everything else works like a charm.
Are there obvious tests I can run (software or hardware) or a full factory reset or else, before sending a heavy unit for repair?
