Excellent condition Michigan Synth Works Monsoon (Mutable Instruments Clouds) Eurorack Granular Audio Processor Module with power cable. Will ship safe, fast, and fully insured. Check my reviews and buy with confidence. Thanks for looking and here is some more information on the Monsoon Reverb.

12HP Clouds Clone with individual controls for each Parameter. Parasites firmware standard but others available on request.

Clouds is a granular audio processor - with a couple of twists.

Unlike granular sample players, Clouds is focused on the realtime granularization of incoming audio signals, and the acquisition of textures from them.

Classic controls such as grain position, size, and pitch are provided. Clouds can superimpose up to 16 grains simultaneously and thus create thick textures. Control over texture density, independently of grain size, is thus provided. An external trigger input allows grains to be seeded in sync with LFOs or rhythmic generators.

To provide a richer variety of timbres, Clouds allows the shape of the grain's envelope to be morphed - from sharp rectangular edges to a smooth bell curve. In addition, a diffusion network can further dissolves the edges of grains into blurry textures.

"Grain mesh" modes automatically adjust grain density, size, and the offset between successive grains in order to generate a continuous stream of audio that can be pitch-shifted / time-stretched in the manner of old-school samplers (or time-domain pitch/time processors).

Finally, to cover various applications of granular synthesis without the need for additional modules, Clouds' comes with four voltage-controlled "blend modes" for mixing and re-routing its output signal: VC dry/wet balance, VC channel crossfade, VC feedback, and VC reverberation.

Clouds' delay memory ranges from 1s to 8s depending on audio quality settings.


  • Recording buffer duration: 1s (32kHz, 16-bit, stereo) to 8s (16kHz, 8-bit µ-law, mono). 4 quality settings.
  • Grain size: 16ms to 1s.
  • Maximum number of concurrent grains: 40 to 60 depending on recording buffer resolution.
  • Grain generation time-base: periodical, randomized, or externally clocked.
  • Grain envelopes: continuously variable between boxcar, triangle, Hann.
  • Playback modes: granular, microlooper/buffer-lock, time-domain pitch-shifter/time-stretcher (WSOLA), spectral.
  • 4-AP diffuser to post-process the granularized signal.
  • Post processing (blending) settings: dry/wet, random panning amount, feedback amount, reverb amount.
  • 4 memory locations for "frozen" recording buffers.

Parasite is an alternative firmware for Clouds/Monsoon. It adds the following main features to the module:

  • The Miverb, a new, full-featured creative reverb mode based on the reverb of the original firmware (itself based on a description of the Lexicon 480L), and inspired in design by the Erbe Verb, with CV control over all parameters. It is largely modeless, probably unrealistic and goes far beyond your traditional reverb;
  • Resonestor, a polyphonic resonator processor with built-in support for your beloved Karplus-Strong synthesis. Plucked or fed with your favorite sound, it spits out strange guitar sounds, lush chords, evolving drones, and more.
  • More envelopes for your grains: the Texture knob allows to select ramp down or ramp up-shaped grains. Square-shaped grains have steeper edges for extra glitch;
  • Availability of much smaller grains compared to the official firmware, and asymmetrical grain envelopes (saws, ramps).
  • Enhanced looping delay and time stretcher modes: tempo syncing with clock multiplier/divisor, support for stereo delay (ping-pong delay) and (crude) open feedback loop, much improved sound quality, faster delay time change.

The four original modes, including the granular of the official firmware are still present, but have been tweaked/extended.
