Mother 32 and DSI Pro 2 CV

[Cires78]

Hi People
Trying to get a DSI Pro2 to play with a Mother 32 over CV. So far, I can get the Pro 2 to play the notes, but I'm having difficulty getting the CV out of the Pro 2 to modulate things like the cutoff etc.

Anyone else done this? Any tips?

thanks,
Eric
