Mutable Instruments Ripples 2020 — Cheat Sheet

Type: Eurorack analog multimode VCF (Voltage Controlled Filter)
Modes: High-pass, Band-pass, Low-pass
Features: Switchable 2-pole/4-pole for BP/LP, voltage-controlled resonance, soft-limiting, built-in VCA on LP out

A. Cutoff Frequency (knob) - Range: 20 Hz → 20 kHz

B. Filter Slope (toggle switch) - 2-pole (12dB/oct; down) - 4-pole (24dB/oct; up) - Affects BP and LP outputs only

C. Resonance (knob) - Self-oscillation: ~75% and up

D. Input 1 Level (knob) - Gain: 0 → 5 (soft clip = overdrive at high setting)

E. FM Attenuverter (knob) - Adjusts amount & polarity of cutoff modulation via FM CV input

Jack	Function	Voltage Range	Notes
In 1	Audio input 1	Modular level	Soft-clipping circuit for overdrive
In 2	Audio input 2	Modular level	Clean input, vintage tone
FM (CV)	Cutoff CV (FM) input	±5V typical	Mod amount set by E; responds to attenuverter
V/OCT	1V/oct cutoff tracking	0–5V (typical)	Keyboard/sequencer pitch CV in
RES (CV)	Resonance voltage control	0–5V	Exponential response
LP GAIN (CV)	VCA for LP output	0V = mute; 5V = 1x	>5V compresses; 7V normalized if unpatched
HP OUT	High-pass output	Modular audio	Slope varies w/ resonance
BP OUT	Band-pass output	Modular audio	2-/4-pole selectable
LP OUT	Low-pass output	Modular audio	2-/4-pole selectable, final output has VCA

Mix both audio inputs for more complex filtering (Input 1 for overdrive, Input 2 for clean).
Select filter slope with the B switch (only BP/LP).
Voltage-control resonance via Res CV for animated textures & pinging.
Self-oscillation: Use as a sine oscillator if resonance is up.
VCA on LP out: Use LP Gain CV for dynamic level modulation or remove cable to use default 7V (fully open).
1V/Oct tracking: Use V/OCT input if you want filter cutoff tracked by sequencer/keyboard (calibrate as needed).

FREQ ~10 o'clock, RES max, no input or FM CV.
Connect keyboard/sequencer to V/OCT.
Listen to LP out, adjust on-board trimmer for proper octave tracking (~4 octaves).
