From the project
A VCF based on the AS3320 VCF Chip
A Eurorack 4-pole low-pass voltage-controlled filter based on the AS3320 chip from Electric Druid — a high-performance 4-pole VCF (CEM3372 family). 12-octave cutoff sweep range and voltage-controlled resonance from zero to oscillation.
- 4-pole (24 dB/oct) low-pass response using all four AS3320 filter stages - 12-octave cutoff range with smooth exponential control - Voltage-controlled resonance — from zero to self-oscillation - Cutoff frequency controlled by a panel pot + CV input with attenuation - Resonance controlled by a panel pot + CV input with attenuation - Three calibration trims: -…
