I got this reply from DSI in another thread as answer to another question. Maybe it helps:
The Pro2's gate out jack is hard wired to the keyboard, so it only gates when you press a key.
In the newest BETA OS versions we added a new set of destinations for the sequencer called "CV TRIG", one for each of the 4 CV outs. This allows you to sequence CV triggers much more easily than before.
If you just want to clock your DFAM, set a sequencer track to one of the CV TRIG destinations, make the necessary CV connections and hit play. With each step enabled for the sequencer track, it's a clock source. You can also use rests and ties to create different rhythms.
Hope this helps!
