hello,
i just add a filter in the nusmuk-audio lib svn.
This is a multi-mode analog style filter.
i think analog fan will love it. If you like 8 bit music, or i you think that phasor~ is a good audio oscillator, this filter is not for you ;-)
It's sound characteristic can be adjusted, but since it's an abstraction, you can tune it more if you dig a bit in the patch.
IMO, it sound is softer and can be closer to a moog filter than the bob~ object.
see attachment.
cheers
