Isn't this the one Thomas Henry used in the PAL filter? It features
switchable phasor/all pass/low pass responses. I didn't realize you
had so many, and at only $10 each... Perhaps someone could make a
run of boards. Eight would be a good companion to a Shepard Function
generator.

Another interesting chip is the 3378. This has VCA, low pass filter w/
VC resonance, AND VC panner. Seems like a good candidate for a VC
stereo mixer.
