Sounds good. I know my svf~ is relatively CPU-hungry, but I haven't gotten around to optimizing it - just kinda abandoned it instead :)

hi Ben,
ok, this is just my pestering again (someone is going to show me a noose soon). There is an svf~ to be released in the cyclone's next snapshot. Differences are
. the clone has 4 outlets, instead of a configurable single outlet
. the clone has no additional resonance inlet (just the q one)
. the clone does no oversampling, uses simpler formulae for coefs (calculated once per block), etc., which all makes a difference of max 340 clones against max 42 of yours svf~s on my machine (think about using it in polyphonic instruments).
. neither is fine-tuned, but the clone does have some protection against over-blowing.
In the max/msp land there is both the fast, 4-out svf~, and oversampled, 1-out (and fine-tuned) 2up_svf~. Btw. the latter is open-source (in a way).

Thanks, I'm glad it's useful.. I think the filter was originally written by Andrew Simper who posted it to music-dsp (musicdsp.org).

The svf~ external is quite nice (IIRC, it's a PD port of a LADSPA plugin by Steve Harris). You can get it as part of the PD
