Kick-focused Resonant Filter
ZV.HP is named after one of Juanito’s early synth friends named Konstantin, whose techno alias is Zvuko Processor. He said, in a Russian accent, "put your kick drums through a high-pass filter and THEN a low-pass filter," It was shocking how well this worked. The filter is basically half a Polyfusion high-pass filter, and carries the refined smoothness over from that excellent design.
Add even the most boring kick, turn the resonance almost to the point of self-oscillation, and then turn the cutoff to a frequency just a couple half-steps above the kick fundamental, and you’ll end up with a wonderfully bouncy kick.
Turn the cutoff up and get "tic tic tic" for when you want to build tension.
Control the cutoff with a big slider CV generator somewhere else, and use it for bass drops, or just let the filter self-oscillate for a sub-bass drone under your mix.
