Simple VCA

[tomg]

Hey Jim, I think I can do it with 2 but it would
suck!

There is that Korg 1 tranny VCA. The trick is you
have to follow it with X200 amp. The most I've been
able to get out of a single stage is about X20 so it
would loose a ton of gain but it would work.......
granted not great but hey it's 2 transistors.

I can think of a pretty good 5 transistor version
though....;-)
