Mutable Instruments Clouds Texture Synthesizer Module, $349!

The Mutable Instruments Clouds is a renowned Eurorack module that offers granular synthesis capabilities, transforming incoming audio into lush, complex textures and soundscapes. Clouds is highly regarded for its ability to take small fragments of audio and manipulate them in various ways, making it a favorite among sound designers and electronic musicians for creating ambient, experimental, and evolving sounds.

Key Features:

Granular Synthesis:

  • Grain Size: Adjustable grain size from tiny particles to larger slices, allowing for detailed control over the texture.
  • Density Control: Determines the rate at which grains are generated, from sparse to extremely dense clouds of sound.
  • Texture: Adjusts the balance between smooth, continuous grains and more discrete, choppy grains.
  • Position: Selects the position within the audio buffer from which grains are taken, effectively “scrubbing” through the captured audio.

Modulation and Control:

  • CV Inputs: Multiple CV inputs for modulating parameters such as grain size, density, position, and pitch, enabling dynamic and evolving sounds.
  • Blend Control: Adjusts the mix between the dry and processed signal, as well as controlling additional parameters like reverb and feedback.
  • Freeze Button: Instantly captures and holds a segment of audio in the buffer, allowing for manipulation independent of the incoming signal.

Sound Processing:

  • Pitch Shifting: Independent control over the pitch of the grains, allowing for pitch shifting and time-stretching effects.
  • Reverb and Feedback: Built-in reverb and feedback effects to add depth and spatial dimension to the granular textures.
  • Stereo Processing: Capable of stereo processing with dual inputs and outputs, creating wide, immersive soundscapes.

Sound Characteristics:

  • Rich and Evolving Textures: Capable of producing a wide range of sounds, from subtle enhancements to complex, evolving soundscapes.
  • High-Fidelity Audio: Designed to deliver high-quality audio processing, ensuring clarity and depth in the output.


  • Sound Design: Ideal for sound designers looking to create unique and evolving textures.
  • Ambient and Experimental Music: Suitable for ambient and experimental music genres, offering the ability to create intricate and immersive soundscapes.
  • Live Performance: Great for live performances, providing real-time manipulation and transformation of audio.
