A tempo-synchronized filter modulation plugin that applies algorithmic patterns to control filter cutoff frequency in real-time. The plugin includes eight pre-programmed rhythmic patterns ranging from basic steady pulses to more complex syncopated and random sequences, with tempo sync divisions from 1/32 notes up to 2-bar cycles. Four standard filter types (low-pass, high-pass, band-pass, and notch) with adjustable resonance and intensity parameter controls to modulate depth across the frequency range. The pattern sequencer automatically advances based on host tempo information.
