Fast answer

Use INT. for standalone timing, or send clock to the selected input. Check SYNC IN because a connected cable overrides the clock-source setting.

Try these checks

  1. Enter GLOBAL with SHIFT + LIVE and inspect CLOCK SOURCE.
  2. Remove an unused SYNC IN connection before checking MIDI or internal clock.
  3. Choose INT. for standalone playback, or start the clock source selected by USB/MIDI.

Diagnose it

Is USB or MIDI selected without a running clock?

Yes: Start the source or select INT. for standalone timing.

No: Check whether a SYNC IN connection is taking priority.

What should happen

The sequencer has the clock source required for playback.

Why this happens

The manual documents both missing-external-clock stops and SYNC IN priority.

If it still doesn’t work

Check the connections and settings described above. If your device behaves differently, email us with its model, firmware version and the steps you tried.
