How to play digitone from external keyboard via overbridge?

I can’t seem to play digi from an external midi source via overbridge in Ableton Live. With the AR all I need to do is arm recording and I can play chromatically. This does not work with digi. Overbridge keyboard does not play digi either. I have tried setting up a midi track, setting output to digi and then go select each of the 16 midi channels none respond. Again this works for AR.
My track channels are set 1-4 for synth channels (1-4). 5-8 for midi channels (1-4)

Been a while since I’ve tried to set this up but after a quick re-read of Overbridge manual found the solution.

can you please share it here?
