Noise Engineering Numeric Repetitor

Binary arithmetic rhythm generator with four gate outputs

8 HP Eurorack module

Numeric Repetitor is a rhythmic gate generator that uses binary arithmetic to create and vary drum patterns. A core 'prime' rhythm is treated as a binary number and multiplied by factor values to produce musically meaningful variations, generating up to four simultaneous gate outputs with a single clock input.

Features

  • 32 prime rhythms derived from all possible 16-unit rhythms via heuristic filtering
  • Binary multiplication of prime rhythms to generate product variations
  • Four simultaneous gate outputs: PRIME plus three PRODUCT outputs
  • Three FACTOR knobs with CV inputs for real-time variation control
  • FACTOR 2 applies binary-AND with 0x0F0F before multiplication
  • FACTOR 3 applies binary-AND with 0xF003 before multiplication
  • BEAT clock input advances on rising edge, resets gates on falling edge
  • MEASURE input for external measure-sync reset
  • RST button pauses and resets to measure start on release
  • SET switch selects between two banks of patterns with orange LED indicator
  • PRIME CV input scalable by PRIME knob
  • 6V low impedance gate outputs compatible with most gate-driven devices

Controls & Jacks (19)

  • PRIME— Selects the base rhythm pattern from 32 prime rhythms. Acts as a scalar for PRIME CV input.
  • FACTOR 2— Controls the variation factor for PRODUCT 2 with binary-and masking at 0x0F0F. Can be modulated via CV.
  • FACTOR 1— Controls the variation factor multiplied by the PRIME pattern to produce PRODUCT 1. Can be modulated via CV.
  • I
  • PRODUCT 3— 6V low impedance gate output of the PRIME pattern with binary-and masking multiplied by FACTOR 3.
  • PRIME— 6V low impedance gate output of the selected PRIME pattern.
  • PRODUCT 1— 6V low impedance gate output of the PRIME pattern multiplied by FACTOR 1.
  • FACTOR 3 CV— Control voltage input for modulating FACTOR 3.
  • FACTOR 3— Controls the variation factor for PRODUCT 3 with binary-and masking at 0xF003. Can be modulated via CV.
  • MEASURE— Resets the beat to the start of the measure on a rising edge.
  • BEAT— Clock input that advances time on rising edge and returns active gates to zero on falling edge.
  • FACTOR 1 CV— Control voltage input for modulating FACTOR 1.
  • FACTOR 2 CV— Control voltage input for modulating FACTOR 2.
  • PRODUCT 2— 6V low impedance gate output of the PRIME pattern with binary-and masking multiplied by FACTOR 2.
  • PRIME CV— Control voltage input for modulating PRIME pattern selection.
  • Eopinsering
  • RST— Pauses time advancement while pressed and resets to start of measure when released.
  • SET— Selects which bank of patterns to use. Status indicated by orange LED.
  • PRIME (CV input)— Control voltage input for modulating PRIME pattern selection.
