Numeric Repetitor is a rhythmic gate generator based on binary arithmetic. A core pattern forms the basis and variation is achieved by treating this pattern as a binary number and multiplying it by another.

This module contains 32 prime rhythms derived by examining all possible rhythms and weeding out bad ones via heuristic. Three of the outputs are variable by knob or CV. It requires only a beat clock to run.

Numeric Repetitor started as a somewhat crazy idea: if rhythms can be represented as binary numbers what basic operations will produce human- meaningful variations?

A simple example: 1000. One downbeat every four units. If we multiply this by three (11 in binary) we get: 11000. Treating the measure as a circle then gives the rhythm: 1001. This is a human significant variation as it gives us an upbeat before the down. Other small number give interesting variations as well. Any power of two (2,4,8,16) perform offsets in time (1000 becomes 0010 with 4 for example). Odd numbers will always keep the down beat (1000 becomes 1100 multiplied by 9).
