control stoermelder 8face in port slot Arm mode ?

I’ve got it setup in port Slot → Arm with a divided clock connected , but now I want to trigger it with some other sequencer … not manually.

any suggestions beyond mapping it to midi as its not exactly what I had in mind.

Use a Sample & Hold module or a trigger buffer between your sequencer and 8FACE.

Please check my video of using 8face in sync https://youtu.be/wGXGqnAP0DQ

wrong video?

No. There is some section on how to use ARM with the trigger buffer as Ben suggested before, look carefully
