Hi Matte,

Shameless plug dept: Magic Smoke Electronics has a Thomas Henry
designed VCF/Quadrature Oscillator kit based on the 2164. We're even
reviewed in the June issue of Electronic Musician. We'll soon have
PCBs and parts kits. www.magsmoke.com

Not a plug but a nice design dept: Charlie Lamm has a dual linear VCA
design based on the 2164 and PCBs at
http://www.charlielamm.com/synth/duallinearvca.php

Several other listers have talked recently about VCO designs based on
the 2164, although I haven't seen any of them. It's a great chip, and
I'm sure it will find more uses in synths.
