[sdiy] VC distortion?

[harry bissell]

A method of VC distortion I have used is to take the CV and invert it... 
so there
is a positive and a negative CV.  I use the CV's to set the level of a 
pair of active
clamps... giving symmetrical clipping. OK it need ~not~ be symmetrical 
if you make
the CVs unequal.

Downside was the amplitude decreased as clipping increased. A VCA following
this could compensate for that if you wanted...

I used an envelope follower to give a constant percentage clipping on a 
dynamic
waveform (guitar).   If I did it again... I'd use my improved envelope 
follower and
it would work much better. I actually sold the prototype to some slacker 
who was
much more impressed with it than I was...
