Liquidus is a warm, compact 4hp 4-pole lowpass filter featuring new release of the SSM2044 chip, made famous in the Korg Polysix, Mono/Poly, Crumar Bit 01, Emu Emulator, Emu SP12, and PPG Wave, amongst others.

It features CV inputs for resonance and filter frequency. It is a great sounding, creamy, fat little filter with good range and well behaved resonance. Its small form factor means it will fit in the coziest of systems including skiffs.

The frequency CV is 1V/octave so you can do tracking filter or create pinged filter percussion effects. Take it into self-oscillation to make it act as an experimental oscillator.

This filter also has a separate EXP CV input with attenuator to allow fun stuff like FM patches. It excels at filter FM, creating very smooth audio rate modulations. Add true fat vintage warmth to your system in just 4HP!
