Disklavier

I had the same problem, compounded with the sustain pedal being released very loudly on some recordings that added an unintended percussive element to the songs! I had the technician come out to adjust (covered under warranty) and everything is fine now. I actually had my original Mark IV replaced by Yamaha because of continuing problems with the right pedal suddenly stopping to work. They could not fix it, so they delivered a new piano. My new Mark IV has also had some problems like yours, but they seem fixable so far. Seems this is a common problem for the Mark IVs.
