The ES 2144 LPF is a classic analog filter with a 24dB per octave slope.
It uses our 2144 submodule which features a reissue of the renowned SSM-2044 IC that formed the filter section for countless vintage synths. The filter’s tone is warm and creamy at low resonance settings and moves into fat, over-driven squelches at the higher end of its range. It will self oscillate when resonance is cranked and outputs a pure sine tone. In addition, the frequency CV input tracks volt per octave allowing it to double as a sine wave VCO.
