sfilter is designed to generate dynamic filtered sequences that enhance your tracks with rhythmic gating, sweeping effects, or evolving filter modulations. It operates using a step sequencer synchronized to your project tempo, allowing the filter cutoff to alternate between two adjustable values over a customizable sequence length. This approach provides precise control over the filter movement, making it ideal for adding motion and groove to any production.

The plugin features a resonant variable filter capable of low-pass, high-pass, band-pass, and notch modes, offering a broad sound-shaping palette. The filter cutoff smoothly varies between the set upper and lower limits, creating rhythmic patterns that can be further enhanced by a tempo-synced LFO. This LFO offers multiple waveforms and adjustable rates, adding extra depth and complexity to the modulation.

With step sequences ranging from 2 to 32 steps and customizable sequence lengths, users can craft intricate rhythmic patterns, while the optional random swing feature introduces subtle timing variations for a more natural feel. Additional controls like wet/dry mix, MIDI CC assignability, and MIDI learn support ensure seamless integration into any setup, making sfilter a powerful tool for transforming sound textures with creative filter movement.
