Hmmm…well, turns out the Karma wasn’t the problem…it was the cable. Ooops. I’ve never had one go bad like that before. Glad I figured it out before I had to drive all over the place to find a repair shop (oh, yeah, that one I said was close to me? Haven’t been certified with Korg for 3 years, but Korg hasn’t taken them off the printed repair list.) Anyway, glad to see Korg QA still in my good books. 🙂
