Doepfer

Hello there

thanks to the people who answered my posting.

I have a question: being new to the Doepfer A100 (System 2, with 
Midi), what connections should I make between an old Roland System 
100 and the Doepfer so I can use the Doepfer on it's own midichannel 
in Cubase, and use the Doepfer to make the System 100 midi on a 
separate channel? Can this be done? Or do they end up on the same 
midichannel? If that is the case, how do I interface the System 100 
and the Doepfer so that I can use the oscillator from the System 100 
on the Doepfer?

Thanks in advance!

Paul
