My yamaha dgx 230 had the same problem too, except, if I pressed it lightly, it sounded as if I were pounding on it. And the bad thing is, it happened to 14 notes, which were the same G#'s and the same D's. But if I press on it normally, it doesn't make a sound. Do u think it has something to do with dust or the rubber pads?
