Clouds Granular Texture Synth - 18HP

Mutable Instruments Clouds

Clouds Texture Synthesizer implements a whole new world of granular audio processing. Instead of having memory banks of recorded sounds for granular processing, Clouds focuses on real-time audio manipulation, providing left and right input channels for full stereo effects processing. Incoming audio is saved into a buffer and is accessible through little pieces of the sound, called grains. These grains can be layered upon each other to create rich textures, similar to the water vapor in the sky coalescing into clouds. The density of the texture is manipulatable with the density control knob, and is independently controllable from the texture grain envelope, as well as the grain size and position in the audio buffer. The audio buffer can capture up to 8 seconds of audio (at the lowest audio quality settings), and up to 1 second of audio at the highest audio quality settings.

Other surprises have been packed into Clouds, including a looping delay, and pitch-shift as well as time-stretching modes. It even contains a spectral buffer with freeze and glitch options.

This is just the main program of Clouds. Because it is a digital module, three other programs are accessible from a factory standard Clouds, and with the Clouds Parasite program, six different "modules" are available, with more being invented by ingenius users.

Mutable Instruments Clouds Features

  • Recording buffer duration: 1s (32kHz, 16-bit, stereo) to 8s (16kHz, 8-bit Q-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).
  • 4-AP diffuser to post-process the granularized signal.
  • Post processing (blending) settings: dry/wet balance, random panning amount, feedback amount, reverb amount.
  • 4 memory locations for "frozen" recording buffers.
  • Stereo inputs and outputs.
  • 1V/Oct input for pitch control.
  • Freeze button and CV input.

The main brain of this patch is the Stepper Acid Sequencer from Transistor Sound Labs. The gate output is split and sent to both the gate input of the Mutable Instruments Elements, as well as the clock input on Grids Drum Sequencer. The second and third channel of Grids are sent into the trigger inputs on Peaks, which is set to Drum Mode, using the kick and hi-hat sounds which are patched into the Veils Quad VCA. The pitch CV output of the Stepper Acid is sent into the 1V/Oct input on Elements, with its output patched into the Veils Quad VCA. The bass drone is made from the Tides Modulator in audio rate looping mode, which is also patched into Veils. The whole mix is then patched into Clouds for reverb and delay. For the morphing timbre on Tides, two LFOs from the Sputnik Quad Function Generator are patched into the waveshaping inputs. For the morphing character of Clouds, two LFOs from the Intellijel Quadra are plugged into the size and texture CV inputs. For the morphing timbre on Elements, two LFOs from the Make Noise Maths are plugged into the strike timbre input and the position CV input. For the shifting rhythms from Grids, two LFOs from the 4MS Quad Pingable LFO are patched into the X and Y scan inputs.

Head in the Clouds Review by Atmos-fear
It took some time to wrap my head around everything Clouds can do. It’s a really deep module, with a number of different modes that offer varying functionality. Once you get familiar with it, the textures you’re able to create with Clouds are simply unmatched by any other module in the world of eurorack.

I ended building a DIY Clouds after purchasing one, though I’d recommend against attempting to do the same unless you have a lot of experience building projects that involve surface mount components. Having multiple clouds in your modular setup is nothing short of amazing though. (Posted on 6/14/16)
