[sdiy] LOG VCA?

[Paul Perry]

Aaron, as it happens, I am just this moment trying for a "one knob"
control to go from log thru linear to antilog
(over a 0 to 10 volt range say).
I guess there is a family of curves that at least LOOK something like
this? Any advice gratefully received.
Application is (among other things) reshaping envelopes. And distortion.
