I'm running a Pulse 2 via midi and one osc of a Nandamonium via cv off the same sequence, then running the cv out of the Pulse 2 (following the same midi notes fed to the Pulse 2 from the BSP) into the second osc in the Nandamonium. The all work at the same time.
I couldn't tell you for the life of me if the notes of the two cv sources match, as the Nandamonium is a drone synth with the strangest cv implementation I have ever come across; it doesn't follow any scale it would seem and does really odd stuff at 2.5v and above, which is great for space noises.
