Daw / Overbridge / MIDI tracks / Digitone

Hi, I can handle Digitone’s 4 main tracks from my DAW and it sends information correctly.

Is it possible to control the other 4 MIDI Tracks as well?
I have not succeeded

Yes, possible.
In Ableton set an external instrument on a MIDI track with MIDI to Digitone and the channel of your MIDI device.
On Digitone you set one of the 4 MIDI tracks to active with the same MIDI channel.
And make sure your device’s MIDI settings are also set to that specific channel and it has a MIDI connection from Digitone’s Thru to its In.
Should be working fine.
