Troubleshooting

Fix the problem.

Start with the symptom. Each guide puts the fastest documented checks first.

Clock and start/stop

The tempo will not follow, or playback will not start with the master. Choose your exact model below.

MIDI connected, but no notes

A controller or sequencer is connected, but the receiving instrument stays silent. Choose your exact model below.

Silent keys or doubled notes

The keyboard is silent, or one played note comes back twice through a sequencer. Choose your exact model below.

Patch changes and saving

The wrong patch is selected, a message is ignored, or settings disappear after power-off. Choose your exact model below.
