Noise Engineering Numeric Repetitor – Cheat Sheet

Type: Rhythmic Gate Generator
Size: 8HP Eurorack
Depth: 0.8"
Power: 2x5 Eurorack, +12V: 50mA, -12V: 5mA

What is Numeric Repetitor?

A binary-arithmetic-based rhythmic gate generator. It outputs four related rhythmic patterns based on a selected core rhythm ("Prime") and up to three rhythm modifiers ("Factor") using multiplication and binary logic.

Quick Start

Patch a clock (trigger/gate) to BEAT.
Patch PRIME and PRODUCT 1-3 outputs to drum modules, envelopes, etc.
Rotate the PRIME knob to pick a core rhythm; adjust FACTOR 1-3 to create variations.
Patch CV or gates to PRIME CV or FACTOR CV 1-3 for dynamic variations.
Optionally patch a reset (start of bar) pulse to MEASURE.

Controls and Jacks Reference

Label	Type	Function	Voltage Range
PRIME	Knob	Selects prime pattern (main rhythm)	-
PRIME CV	CV In	Modulates `PRIME` pattern selection	0–5V typical
FACTOR 1-3	Knobs	Selects variation factor for each PRODUCT output	-
FACTOR CV 1-3	CV In	Modulates each `FACTOR` knob	0–5V typical
SET	Toggle/Switch	Selects bank of rhythms	-
BEAT	Trigger In	Clock input; advances step on rising edge	Standard gates/triggers
MEASURE	Trigger In	Resets sequence to start of measure	Standard gates/triggers
RST	Button	Pauses time; resets to start when released	-
PRIME	Gate Out	Main rhythm (core pattern gate)	0V (low), 6V (high)
PRODUCT 1-3	Gate Out	Three rhythm variations based on factors	0V (low), 6V (high)

Output Voltage

All gate outputs are 0V (low) and 6V (high).
Low impedance, compatible with most gate-driven modules.

Patch Suggestions

Basic: Clock -> BEAT; PRIME/PROD1-3 -> Percussion Gates
Variation: Use CV/gates on PRIME or FACTOR for related, evolving patterns (e.g., send a random gate or modulated LFO to a FACTOR CV input).
Measure Reset: Trigger MEASURE to keep everything in sync with your main clock.
Creative CV: Divide clock, use sequencers or random sources to modulate FACTOR or PRIME CVs for pattern variation.

Notes on Patterns

32 handpicked rhythmic patterns ("Primes")—all 16 steps, always start on step 1, musically valid (see manual for detailed grid).
Each FACTOR applies different binary arithmetic for human-friendly variations.

Tips

Turning FACTORs or applying CVs creates time offsets, fills, syncopations, and other pattern variations.
Use SET bank switch for expanded pattern selection.
