2144 LPF

The ES 2144 LPF is a classic analog filter with a 24dB per octave slope.

It uses the 2144 submodule which features a reissue of the renowned SSM-2044 IC that formed the filter section for countless vintage synths (CMI Fairlight, Kawai SX-240, Korg MonoPoly, Polysix, Octave Cat). 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.

Available assembled:

• Analog 4-pole low pass filter
• Renowned SSM-2044 filter topology
• CV over frequency and resonance
• Frequency CV tracks volt per octave
• Capable of self oscillation
• Doubles as sine wave VCO with V/Oct tracking
