de la Mancha has released sfilter a filter effect plug-in for Windows PC.

sfilter creates a stepped filtered sequence, to create gating, sweeps or rhythmic modulation of filter cut-off. It uses a variable state filter, varying between 2 adjustable cut-off values according to a tempo-sync’d step sequencer. An LFO can also modulate the filter for extra movement.

sfilter features

• tempo-sync step sequencer, with 2 to 32 steps over a sequence length of 2 to 32 beats.
• resonant variable filter, LP, HP, BP and notch.
• filter cut-off varies between upper and lower cut-off values, in either direction.
• tempo sync LFO, with 6 waveforms and settings from 1/16 beat to 96 beats.
• random swing for step sequencer.
• wet/dry mix control.
• midi CC and midi learn.

sfilter is available for download free of cost (donations are appreciated).
