Syncing issue from Ableton via Digitakt / Heat to MD

I’m unable to sync via either DT or Heat to MD. Ironically I’ve tried (same thing) through my cheapo Roland Duo interface and it works as expected, but must have some internal settings wrong or Overbridge is messing it up somehow. I have both Elektron boxes set to receive clock and sync and have got a cable from MIDI out to the the MD MIDI in. Ableton is set to Output track and sync. Can’t see what I’m doing wrong! Any help appreciated :+1:
