Mutable Instruments Clouds – Cheat Sheet

A quick-reference guide to the Clouds granular audio processor for Eurorack.

Quick Start

Patch audio into L (and optionally R) input.
Patch stereo output (L/R) to mixer/output.
Twist knobs to manipulate grain position, size, pitch, density, texture.
[Optional] Patch CV into desired CV ins for dynamic modulation.
Press FREEZE to capture a sound, manipulate the buffer, or scan through frozen grains.

Controls Reference

Knobs

Knob	Function
POSITION	Where in the buffer grains are sourced (back in time: CW = earlier)
SIZE	Grain length
PITCH	Grain playback speed (12 o'clock = normal pitch)
IN GAIN	Audio input gain (-18dB to +6dB)
DENSITY	Grain overlap/timing (CW = denser/random, CCW = denser/constant, noon = none)
TEXTURE	Morphs grain envelope shape; past 2 o'clock activates diffuser
BLEND	Controls one of: Dry/Wet ↔ Spread ↔ Feedback ↔ Reverb (select via button B)

Buttons

Button	Function
FREEZE (A)	Capture/freeze buffer (toggle)
Blend Parameter/Audio Quality (B)	Select parameter for BLEND knob/CV, or hold+tap to set audio quality
Load/Save (C)	Load or save frozen buffers; double-action, see manual for details

LEDs

Bargraph: Input/output level, setting indicators, parameter values.
Color indicates: blend parameter (green), buffer slot (red/green), calibration (orange).

Inputs & Outputs [Voltage Range: All CV INs ±5V]

Jack #	Label/Use	Type	Description
1	FREEZE	Gate In	Gate high = freezes buffer (same as button).
2	TRIGGER	Trig In	Generates a single grain per trigger (micro-sample playback at DENSITY noon).
3	POS CV	CV In	Modulate grain buffer position (±5V)
4	SIZE CV	CV In	Modulate grain size (±5V)
5	V/OCT	CV In	1V/Oct pitch tracking of grain playback (±5V)
6	BLEND CV	CV In	Modulate selected blend parameter (±5V)
7/8	IN L / R	Audio In	Stereo input (R normalled to L if unpatched)
9	DENSITY CV	CV In	Modulate grain density/overlap (±5V)
10	TEXTURE CV	CV In	Modulate envelope/diffusion/texture (±5V)
11/12	OUT L / R	Audio Out	Stereo output

Blend Parameters

Dry/Wet
Stereo Spread (random panning per grain)
Feedback Amount
Reverb Amount
Select parameter using Blend Parameter/AQ button (B); indicator LED shows selection.

Freezing & Saving

FREEZE: Stops recording; process sound in memory.
Save/Load Buffer:
Hold Load/Save 1s, select slot (1–4), confirm to save.
Tap Load/Save, select slot, confirm to load.

Calibration

1V/Oct calibration: See manual (requires accurate CV source).

Audio Quality

Hold Blend Parameter/Audio Quality button for 1s; tap to cycle:
32kHz/16-bit
32kHz/8-bit µ-law
16kHz/16-bit
16kHz/8-bit µ-law

Tips

Add random modulation to Position or Pitch for lush textures.
Use audio out as modulation noise source.
Fast note sequences to V/Oct = chord grains.
Short FREEZE pulses = capture micro-textures.

Troubleshooting

No effect?
Dry/Wet blend may be fully dry. Use Blend Parameter/AQ button to select dry/wet, adjust BLEND knob.
