I don't fully grok the method used in vcf~, but if you want to have consistent filters with reproducable algorithms, you could build filters with the elementary filter objects provided in Pd, i.e. rzero~, rpole~, czero~ and cpole~ or biquad~. Then the filter program is in the diagram. Common methods to design filters are the Filter-EQ-Cookbok and J.O. Smith's filter/dsp website. The rj-library http://trac.rjdj.me/wiki/RjLibnew includes some helpers for this.
