Well, the 7-pin sound connector only has one input, and that's the
analog input. If you want to hook the CDS to the sound connector, the
Ensoniq _has_ to digitize the input (which isn't something to do with
serial data). It shouldn't be too hard to get a feedback system... As
I've said in email, I've done it before. The only problem was that the
sound lagged behind the input by about half a second (very annoying).
When I get some more time, I'll see if I can reduce/eliminate that
lag.
