AOFN Audio GrizzlyGrizzly is a free stereo modulator modelled on the 1979 Gristleizer circuit, as used by Chris Carter of Throbbing Gristle. An internal LFO drives a modelled JFET stage in two modes: VCA, which controls the amplitude of the signal, and VCF, which sweeps a lowpass filter across it. Features: VCA mode: tremolo, rhythmic gating, choppy pulse effects, ringmod-adjacent tones above 20 Hz. VCF mode: autowah, dub filter pulses, slow cutoff sweeps. LFO waveforms: triangle, square, saw up, saw down. Speed: 0.01 Hz – 30 Hz free, or host-synced 1/1 to 1/32 note divisions. Shape control: slope asymmetry (triangle) / duty cycle (square). Offset: controls what fraction of each LFO cycle drives the effect. Bias: sets the resting position of the modulation (attenuation floor in VCA, base filter brightness in VCF). Drive: −12 to +24 dB pre-gain modelling the original op-amp stage. Spread: inter-channel LFO phase offset for stereo widening and auto-pan. Level: output trim. No presets, no menus.
