A free, component-modeled recreation of the legendary SSM2044 filter chip. The circuit is modeled stage by stage from the original schematics — not a generic ladder approximation — capturing the exact four-pole lowpass that shaped the Korg Polysix and Mono/Poly, the E-mu SP-12 and SP-1200, and the PPG Wave. From silky-smooth sweeps to gritty drum crunch to screaming self-oscillation.

Features:
– Component-modeled from the original SSM2044 schematics
– The filter heard in the Korg Polysix & Mono/Poly, E-mu SP-12 & SP-1200, PPG Wave and others
– Classic 4-pole (24 dB/oct) resonant lowpass
– Additional highpass mode — beyond the original hardware
– Resonance up to true analog-style self-oscillation
– Cutoff, resonance & drive controls
