Ripples Liquid Filter Module description:

The Mutable Instruments Ripples Liquid Filter Module is a liquid filter module, featuring three modes, with self-oscillation available, and a width of 8 HP. The Ripples delivers a classic, big-sounding analogue four-pole filter in a small 8-HP package, continuing Mutable Instruments’ lineage of warm and tasty filters started by the Shruthi SMR4 MKII and 4-Pole Mission. Three filter modes are available: 2-pole band-pass, 2-pole low-pass, and 4-pole low-pass.

Self-oscillation is available for all modes and produces a clean sine-wave on the LP4 output. Unlike many classic 4-pole designs, this filter does not suffer from “loudness drop” when resonance is increased. The resonance loudness compensation circuit brings a slight tone coloration reminiscent of the Roland SH/Jupiter filters, with a very round and “liquid” resonance.

The main features of the Mutable Instruments Ripples Liquid Filter Module include:

  • Inputs: Signal in; Frequency CV 1; Resonance CV; Frequency CV 2; VCA level
  • Controls: Cutoff frequency, 18Hz to 18kHz; Resonance (self-oscillation at 80%); Attenuverter on Frequency CV
  • Outputs: 2-Pole BP; 2-Pole LP; 4-Pole LP; 4-Pole LP Attenuated by VCA
  • Fully Analogue
  • Based on SSM2164 Low Noise/Distortion Quad VCA chip, & LM13700 OTA
  • Frequency CV Inputs Impedance: 100k
  • Audio Input Impedance: 75k
  • Resonance & VCA CV Input Impedance: 30k
  • Open-Source Hardware
