What Do Position, Size, Texture and Density Do in Mutable Instruments Clouds?

Clouds Controls Explained

Understanding four primary controls is the key to mastering Clouds:

• Position

• Size

• Texture

• Density

Together they determine how the granular engine reads and processes audio.

Position

Position determines where Clouds reads from inside the audio buffer.

Moving the Position control allows you to scan through recorded audio and explore different parts of the captured sound.

When Freeze is active, Position becomes especially powerful because you can slowly navigate through a static recording and discover details hidden inside the source material.

Size

Size determines the duration of each grain.

Small grain sizes create:

• Sparkling textures

• Digital clouds

• Microscopic sound fragments

Large grain sizes create:

• Smoother textures

• Longer sonic gestures

• More recognizable source material

Changing Size can dramatically alter the character of the output.

Texture

Texture controls the grain window.

The grain window determines how individual grains fade in and out over time.

Different settings can produce:

• Smooth transitions

• Sharp attacks

• Diffuse atmospheres

• Rhythmic textures

Texture strongly influences the perceived softness or sharpness of the resulting sound.

Density

Density determines how many grains are active simultaneously.

Low Density settings produce:

• Sparse events

• Transparent textures

• Individual grain articulation

High Density settings produce:

• Thick atmospheres

• Dense sound clouds

• Rich ambient textures

For ambient and generative music, Density is often one of the most influential parameters.

Modulation Possibilities

All major Clouds parameters can be modulated via external control voltage.

Popular modulation sources include:

• LFOs

• Random voltages

• Sample & Hold modules

• Function generators

• Sequencers

Slow modulation of Position, Size, Texture and Density can create evolving soundscapes that remain interesting for extended periods.
