Ian Fritz's Threeler VCF

Third-order VCF with switchable response (LP/BP/HP) for each of the three stages, in four different combinations. It also has VCable resonance. Output of each stage is also available.

"I'm partial to 3d order, musically. My 3d order filter has four switchable combinations of HP/LP stages and output from each stage.

Demos may be heard/seen here:


Several people have said this is the all-time best-ever filter. I don'tknow about that -- I've always been more interested in the waveshaping approach to timbre -- but please listen and see what you think about the musicality."


Kit is $175.
