I'm going to try to do something similar with some EE friends, and any part
recommendations would be great. We were thinking

PC --> RS-232 or USB --> PIC18F452 --  ???  --- control voltage --->
analogue synth madness!

to make a computer to conltrol voltage interface for controlling analogue
synthesizers. Basically this would be like a midi-CV converter, except
without the midi part, the idea being to have higher resolution signals from
the computer becoming CV signals instead of low res 9600 bps 7 bit midi
signals. Any suggestions?

Thanks,
Iain
