Probably a noob Question?

Sooo I just stumbled over and old shabby Rytm MK1 at my local swap meet in Berlin and now try to figure this thing out. I gut it connected to my OT (Midi) and my DAW.
Main transport signal goes from DAW -> Octatrack -> Rytm
I got all my Midi settings set up accordingly.
When I start the clock everything runs smooth. However, ones I change a setting of a drum sound on the AR the clock of the AR stops after a couple of bars.

Maybe there’s something I need to set up differently?

Help is appreciated!

The AR will stop if it is expecting to receive MIDI clock messages but it is not receiving them. You might check whether you are sending clock from the OT or not.
