This filter is much better than the one currently used in in the VCF of
AlsaModularSynth. It's the best open source implementation of the Moog VCF
that I know of. I highly recommend users of AlsaModularSynth to replace
any VCF module in a patch by the third Moog VCF of Alfons' LADSPA plugins.

I have recorded some samples of an original analogue Moog filter (Minimoog
Voyager) available at ftp://ftp.suse.com/pub/people/mana/moog_samples
for comparison.
