Disklavier

I don't have a service manual to send. However, I should point out that I have frequently encountered situations in which the Mark IV does one or more of the following:

--stops sending MIDI data

--stops receiving MIDI data

--doesn't record

--doesn't play back

The fix has always been a cold reboot. This means:

--shutting down the Disklavier

--unplugging it from electricity

--waiting an interval of time

--plugging it back in and starting it back up.

Unfortunately, there is no way to tell how long you should unplug it from the wall. You can try this procedure, unplugging for a minute. If that doesn't work, try again, unplugging for 45 minutes.

Other troubleshooting measures normally include:

--making sure that the MIDI plugs are not backwards (if you are using MIDI cables)

--making sure that the Disklavier's MIDI In and Out choices are correct (especially the choice between MIDI and USB)
