More Nonlinear

[Scott Gravenhorst]

Ok, this weekend is "nonlinear feedback filter mad scientist" weekend.
I've decided on a state variable filter because it can be converted
easily to a simple single pole LP filter with an SPST switch.  It also
has two feedback paths to mess up with nonlinearities.  I've come up
with 5 or 6 simple nonlinear devices that I can patch in to test.  I
will be using an LM13600 for the OTAs.  For now, I will control the
nonlinear stuff with a simple pan pot to pan between a linear path and
a nonlinear one or maybe two different nonlinear paths, but if it
sounds wierd/good, I will eventually devise some kind of VC panning
system.

Heck, I need another filter anyway.

Wish me luck, and if I get usable results, I'll put the schemos on my
FatMan site.
