Fast answer

When CLOCK RECEIVE and TRANSPORT RECEIVE are both enabled, Octatrack waits for clock after Start or Continue. Send clock as well, or disable CLOCK RECEIVE if you deliberately want internal tempo with external transport.

Try these checks

  1. Open PROJECT → MIDI → SYNC and inspect CLOCK RECEIVE and TRANSPORT RECEIVE.
  2. For full external sync, enable both and make the sender transmit both clock and transport.
  3. For internal tempo with external start and stop only, leave TRANSPORT RECEIVE enabled and disable CLOCK RECEIVE. Test the intended mode.

Diagnose it

Is the sender transmitting Start but no clock?

Yes: Supply clock, or deliberately use transport-only reception.

No: Check that both messages reach MIDI IN.

What should happen

Playback uses the intended tempo source rather than waiting for a clock that never arrives.

Why this happens

The OS 1.40A manual documents the wait and the transport-only alternative.

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.
