I recently posted on the Non-Linear Digital Implementation of the Moog Ladder Filter. There were a couple of comments including the following by polardark:
"Antti Houvalainen who authored this paper has also made the free VSTi softsynth ASynth which uses this moog filter, as well as a modelled MS20 filter and an Oberheim Xpander filter. The same filter is also used for Basement Arts Frantic VST filter effect. Both well worth trying out, in my opinion... "
So I went looking and found ASynth on KVR. I clicked on the download link and ended up on Antti's VST plugin page, with samples and downloads. Title link takes you there. Thanks to polardark for taking the time to comment.
