Disklavier

Hi Bob,
 
I don't know if this will help, but it certainly couldn't hurt.  Have you
tried resetting the control unit back to default settings ?
 
"The details are in Chapter 12 of the Advanced Owners Manual on page 72.
Basically, you push Function, then Reset, then Settings to do a Reset.
Leave the menus for the Memory Disks alone"
 
Good luck,
 
Michael

Subject: [disklavier] Need help with Disklavier Mk III gone mute



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
