My Disklavier Mk III has suddenly gone mute, on all instrumental
accompaniment playbacks. If I'm playing a Yamaha PianoSoft Plus
diskette, the piano still plays fine acoustically -- but no other
instrumentation plays at all through the speakers, it just stays
silent. I know that the speakers are OK, because I can switch the
piano to Silent Mode and the synthesized piano voice then plays fine
through the speakers (but still no other instruments).
Strangely, if I try to play a standard MIDI file, not only is the
MIDI instrumentation totally silent, but in this case the piano will
not even play acoustically!
Also, if I try to play just a regular audio CD, which normally would
work, there is no sound at all from the speakers.
Given that my local dealer has a minimum two-month (!) wait for
service appointments (which I consider totally unacceptable), can
anyone suggest any troubleshooting or diagnostic steps that I can
take in the meantime?
Thanks in advance for any help!
- Bob

Are you getting any error messages at all? This sounds like a problem with your tone generator, the module that makes MIDI (synthesized) sounds for ensemble playback. It makes sense that it wouldn't affect the piano voice, since it operates independent of the GM and XG voices. I'm not sure what to think of the fact that CDs don't play, however, since that wouldn't be related to your tone generator, and since your speakers are working. I suppose it is possible that you have the L/R balance off or you have accidentally set the piano/ensemble balance so that you can't hear anything but the piano. If you have checked these things (and even if you haven't, I guess), the easiest thing to do is reset the factory defaults. In my experience, this fixes odd behaviors from the Mark II or III. I don't have a Mark III anymore, but to the best of my memory, you press function, then the ">" (right arrow) button, and you'll get some RESET options at the very end of the menu. Try choosing to reset "Setup" first, as the other options erase the storage memory and probably aren't related to your problem anyway. Let us know if this works
