Can anyone be of help in syncing the Sub 37 arpeggiator to a modular system?

Currently using Pamela's New Workout as a master clock. I am triggering 2 Pico Drum units with this, and would also like to use this to control the tempo of the Sub 37 arp. Since the Sub 37 has minimal CV in's, I am running PNW -> Doepfer 192-2 -> MIDI out --> MIDI in on Sub 37.

Any help would be greatly appreciated!
