Ditto ; )

I'd kinda assumed you could make one by just controlling the VCA of an
oscillator (manually controlling frequency) using an envelope follower fed
by a mic, but I've been told this is not the case.
What else do you need?  Can such a thing be made CHEAP, say just shaping
the audio out of a synth?


(if anyone's wondering why I'm still around, so am I!)
 ; )

(But if you could please CC replies to me just in case)
