Dave Smith Instruments has pointed us in the direction of this short video by Magnus Gladén which shows a DSI Pro 2 controlling modular synths.
Magnus had this to say, "My friend brought his Pro-2 over. We decided to have some fun. We use the Pro-2's OSC's and sequencer. The Pro-2 is also controlling the modular synthesizers envelopes and Q960 sequencer. We filter the Pro-2 thru the modular. The modular synth also makes the kick drum as well as trigger the Korg MS20 which is making the snare drum."
