Looks like I'm dead in the water. Just got word from Advanced Musical-I'd shipped to them for repair. They claim it can't be done, the problem is in the basic operating ROMs which Yamaha doesn't have anymore, neither do they have a complete mainboard these chips reside on. Hard to believe this is non-repairable just for this reason, it looks almost perfect otherwise. What a waste. I'd even be willing to ship it to Yamaha Japan if I thought they could repair it, I bet they could but I have no ides how to communicate with them and I don't speak or write Japanese. If anybody else here has any ideas, I am paying attention. I hate to see this module be completely useless. MY old DTX 2.0 has lasted for so many years I can't even remember, and never even a hiccup. God only knows what the original owner did to shmeck this one. I can't imagine what it would take to pooch this, must have taken quite a foobar.
