I am seriously considering the Oberheim Two Voice Pro, but since I already own a DSI Pro 2, I am also considering getting two separate SEM modules instead and run them via the Pro 2. Is there anything that can be done on the Two Voice Pro that could not be done with this set-up? I guess the sequencers are different, but I guess there is nothing that the TVP sequencer can do that the Pro 2 sequencer can not do? Advice, anybody?
