Start with the symptom

What has stopped working?

Troubleshooting

Clock and start/stop

The tempo will not follow, or playback will not start with the master.

Troubleshooting

MIDI connected, but no notes

A controller or sequencer is connected, but the receiving instrument stays silent.

Troubleshooting

Silent keys or doubled notes

The keyboard is silent, or one played note comes back twice through a sequencer.

Troubleshooting

Patch changes and saving

The wrong patch is selected, a message is ignored, or settings disappear after power-off.
