Noise Engineering Melotus Versio

Granular texturizer for doombient and beyond

10 HP Eurorack module

Melotus Versio is a stereo granular texturizer and delay that transforms audio into lush, evolving textures using grain-based processing. It offers extensive control over grain density, direction, length, and randomness, with a filter that adds haunting subharmonics or shimmering octave-up shimmer. Designed for doombient and experimental music, it can serve as everything from a rhythmic grain delay to a completely transformative sound sculpting tool.

Features

  • Stereo granular texturizer with up to 24 simultaneous grains
  • Grain direction control: forward, reverse, and chaos
  • Grain freeze via toggle, momentary button, or CV gate
  • Tap tempo and external clock input for rhythmic grain triggering
  • Clock divider/multiplier with 9 ratio steps when in Clk mode
  • Cohere control to reduce or increase randomness of grain triggering
  • Bipolar Tone control: lowpass filter with detuned subharmonics left of noon, highpass with octave-up shimmer right of noon
  • Regen feedback with input-ducking behavior past 3 o'clock
  • Grain length from 0.2s to 2s
  • Delay time from 0.1s to 8s
  • CV inputs for Sparse, Tone, Length, Regen, Delay, and Cohere
  • Stereo audio inputs and outputs

Controls & Jacks (27)

  • Delay CV— CV input for Delay time parameter.
  • Sparse CV— CV input for Sparse grain count parameter.
  • In R— Right channel audio input.
  • Tone CV— CV input for Tone filter parameter.
  • In L— Left channel audio input.
  • Regen CV— CV input for Regen feedback parameter.
  • Status LED 1— Status indicator LED (yellow on boot with standard firmware).
  • Out R— Right channel audio output.
  • Flow CV— CV/gate/trigger input for Flow control. Behavior depends on Mode setting.
  • Delay— Sets the delay time of the grains from 0.1s to 8s. When in clocked mode, acts as a clock divider/multiplier with settings: 1/8, 1/4, 1/2, 3/
  • Cohere CV— CV input for Cohere randomness parameter.
  • Regen— Feedback control. All the way to the left minimizes feedback. As the knob is turned, feedback increases, creating longer textures and comple
  • Sparse— Changes the number of grains from 24 at minimum to 1 at maximum. Grains become more obvious as the knob is turned up.
  • Mode— Mode selector that sets the Flow button behavior: Clk (tap tempo/clock input), Hld (grain-freeze toggle), or Frz (momentary grain freeze).
  • Length CV— CV input for grain Length parameter.
  • Out L— Left channel audio output.
  • Flow— Button for Flow control. Behavior depends on Mode switch: in Clk mode acts as tap tempo, in Hld mode freezes/unfreezes grains on toggle, in
  • Cohere— Reduces the randomness of grain triggering as the knob is turned up.
  • Length— Changes the length of the grain from 0.2s to 2s.
  • Status LED 3— Status indicator LED (yellow on boot with standard firmware).
  • Blend— Dry/wet mix. Fully counterclockwise is 100% dry (input signal only), fully clockwise is 100% wet (processed granular output only). At noon,
  • Status LED 2— Status indicator LED (yellow on boot with standard firmware).
  • Direction— Grain playback direction. Selects between backward, chaos, and forward.
  • Tone— Bipolar filter and effects control. To the left of 12:00, acts as a lowpass filter and adds detuned subharmonics. To the right of 12:00, act
  • Status LED 4— Status indicator LED (orange on boot with standard firmware).
  • Rev/???/Fwd— Grain playback direction. Selects between backward, chaos, and forward.
  • Clk/Hld/Frz— Mode selector that sets the Flow button behavior: Clk (tap tempo/clock input), Hld (grain-freeze toggle), or Frz (momentary grain freeze).
