Ripples
Liquid filter
There’s a million fat-sounding Eurorack filters out there… but they don’t all bring you lasagna at work.
Ripples delivers a classic, big-sounding analog 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.
3 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 4-pole low-pass output is additionally sent to a VCA. This makes Ripples a good final stage module for an inexpensive/space-constrained subtractive synthesis synth voice.

A multimode filter
- 2-pole band-pass.
- 2-pole low-pass.
- 4-pole low-pass.
- 4-pole low-pass processed by an internal VCA - the perfect “end of subtractive chain” output!
All the CV inputs you need
- Un-attenuated frequency CV, calibrated for 1V/Oct tracking of the self-oscillation tone over 4 octaves.
- Frequency CV with attenuverter.
- Resonance CV. Self oscillation starts at 4V. Control voltages above 5V are non-linearly compressed, for fine control of resonance overdrive.
- VCA level for the LP4>VCA output.
Specifications
- Cutoff knob range: 18Hz to 18kHz.
- Fully analog, based on the V2164 low noise/distortion quad VCA chip, and LM13700 OTA for that extra bit of non-linearity.
- Frequency CV inputs impedance: 100k.
- Audio input impedance: 75k.
- Resonance and VCA CV input impedance: 30k.
- All CV inputs handle audio-rate modulations.
