Hello list,
A new LADSPA plugin, "moogvcf-1.1", has just been uploaded to
<http://alsamodular.sourceforge.net>.
It contains three versions of the 24 dB/oct lowpass Moog VCF, in which
I try to emulate some of the non-linear behaviour of the original.
Enjoy !

Are you planning to do other filters too
(High-,Band-,Notch-)?
Yes, but not immediately -- ATM there's a number of other
things such as deadlines :-[ I need to attend to, which
explains why I am at work on a saturday.
It may be possible to have some sort of higpass or bandpass
response by outputting intermediate values, for example
x at line 179 or c2 at line 183 in moogvcf.cc, but I have not
tried this.
Meanwhile I'm glad you like it - thanks for the flowers :-).

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.
