Noise Engineering Gamut Repetitor

Quad looping random generator with 27 scales

10 HP Eurorack module

Gamut Repetitor is a four-channel random quantized voltage generator with looping, range, key, and scale settings. Generate four random voltages by sending triggers, then lock in a pattern by reducing the Length control. Features a built-in quantizer with 27 selectable scales organized by major/minor/symmetric families, flavor variations, and note count. Trigger inputs are normalled top to bottom so a single clock can drive all four channels.

Features

  • Four independent channels of quantized random voltage generation
  • Loop length control from 1 step to infinite (continuous random)
  • Built-in quantizer with 27 selectable scales via three switches
  • Scale families: major, minor, and symmetric
  • Root note control sets the tonal center
  • Spread control adjusts deviation from root, 0 to 24 semitones
  • Down/Up shifts the voltage range above or below root
  • Trigger inputs normalled top to bottom for single-clock operation
  • Trigger outputs with passthrough or rhythm generation mode
  • CV inputs for Root, Length, M/M/S, Dn/Up, Scale, and Spread
  • Reset input returns all channels to loop start on next trigger
  • Length LED indicates loop length: red for multiples of 2, blue for 3, purple for both

Controls & Jacks (27)

  • Root— Sets the root note of the scale used to generate random voltages.
  • Spread— Controls the amount of deviation from the root note, from 0 to 24 semitones.
  • Length— Sets the loop length. Fully clockwise generates random voltages continuously. Turn down to loop the most recent voltages. Values divisible b
  • Down/Up— Shifts the range of voltages around the root note. At maximum, the range extends above root; at minimum, below root.
  • Maj/Min/Sym— Selects between major, minor, and symmetric scale families.
  • Flavor— Changes the style of the selected scale.
  • Count— Changes the number of notes used in the scale.
  • Reset— Resets all four channels to the start of the loop on the next trigger. Hold for a few seconds to toggle trigger outputs between passthrough
  • In 1— Trigger input that advances channel 1 or generates a new random voltage. Normalled to In 2/3/4.
  • In 2— Trigger input for channel 2. Normalled from In 1 and to In 3.
  • In 3— Trigger input for channel 3. Normalled from In 2 and to In 4.
  • In 4— Trigger input for channel 4. Normalled from In 3.
  • Reset In— Trigger input that resets all four channels to the starting value of the loop on the next trigger when Length is less than infinite.
  • Root CV In— CV input for Root parameter. 0V to +5V range.
  • Length CV In— CV input for Length parameter. 0V to +5V range.
  • M/M/S CV In— CV input controlling the Maj/Min/Sym switch position.
  • Dn/Up CV In— CV input for Down/Up parameter. 0V to +5V range.
  • Spread CV In— CV input for Spread parameter. 0V to +5V range.
  • Scale CV In— CV input controlling all positions of Flavor and Count switches.
  • Trig Out 1— Trigger output for channel 1. Passes through input triggers by default; hold Reset to enable rhythm generation mode.
  • Trig Out 2— Trigger output for channel 2.
  • Trig Out 3— Trigger output for channel 3.
  • Trig Out 4— Trigger output for channel 4.
  • CV Out 1— Quantized 1V/oct random voltage output for channel 1. 0V to +5V range.
  • CV Out 2— Quantized 1V/oct random voltage output for channel 2.
  • CV Out 3— Quantized 1V/oct random voltage output for channel 3.
  • CV Out 4— Quantized 1V/oct random voltage output for channel 4.
