<font size=3>Hi Perry,<br><br>
Attached are MoogVCF.cpp and MoogVCF.h written by Nick Porcaro based on
input from Tim Stilson for the RealSimple project. We also plan to submit
other works from that project for STK consideration (just need time to
figure out what makes sense to submit).<br><br>
Cheers,<br>

The Moog instrument uses 2 sweeping filters, but<br>
that's not the same as the famous Moog 4-pole filter.<br>
It's possible that Tim Stilson (he used to be<br>
stilti@ccrma.stanford.edu, and might respond to that)<br>
has a digital emulation of the Moog 4-pole laying<br>
around. He did research in that back when, and he<br>
also did the very first Linux port of STK 1.0.<br><br>
Hope you find this out, as it would be cool to<br>
have in the STK suite.<br><br>
