Control Digiton as a Midi Sequencer via Ableton Live

Hi everyone - hope thsi wasnt asked before - couldn’t find a solution here, yet.
So I would like to trigger an external synth on Ableton Live Midi Track via Digitone overbridge.
Let’s say my ext. Synt is on Midi Channel 5 .
I can trigger it on Digitone Hardware with ease - but when I try it via the DAW I won’t get any signal.
Trying Midi Tracks 1-4 (for the 4 synths in DTn) it works perfectly fine.

Midi in (keybord controller)
Out to Midi Patchbay - from there to ext Synth.
I picked the right channel on DTn Interface since I can trigger it with the internal Sequencer.
any ideas?

thanks!!

Do you have your Monitor set to “in” on the MIDI track in Ableton Live?
