That filter >

Customise the personality behind the filter itself, selecting from a low-pass (default), band-pass or high-pass model in the upper left. Increase the Smoother parameter to make the filter ‘drift’ or ‘glide’ between different steps; the Filter Range parameter determines the width of the band-pass, or the base cutoff of the low- and high-pass filters; Resonance we all know. To achieve a subtle moving filter effect, run a slow-moving sequencer with the Smoother cranked right up and the Range way down.
