[sdiy] VCA response - continously variable between linear and exponential

[neil harper]

hey all,
i'm looking for some advice/pointers on how to get a VCA response curve
to be continuously variable between linear and exponential. i can do
switchable between the two, but is there any trick to getting everything
inbetween?

if it helps, my VCA is lm13700 based but i don't mind starting with
something else.
