Subject: [linux-audio-dev] Moog VCF in SpiralSynthModular

Hello,

Today I discovered that SpiralSynthModular has a Moog VCF. From the
Stilson paper (http://ccrma-www.stanford.edu/~stilti/papers/moogvcf.pdf)
I learned that digitizing the Moog VCF is a nontrivial problem. So I
would like to ask two questions

1) On which papers/information/sample code is the Moog VCF in SSM based ?

2) Is there a cookbook document for the Moog VCF ?

A question I don't want to ask: Are there any patents in conjunction with
the digital implementation of this filter (the "original" Filter was
patented by Moog in the sixties) ?

Matthias
