Grizzly

Grizzly 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 – 60 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.
