4ms Rotating Inputs

Name: 4ms Rotating Inputs
Brand: 4ms Rotating

Eurorack clock divider module with CV-controllable rotation and nonstandard divisions

Overview

The 4ms Rotating Inputs is a Eurorack clock divider module that generates eight divided clock tempos from a single input. It features a CV Rotate input to dynamically re-assign the division number of each output jack and a Reset input to synchronize with an external clock. Designed for experimental timing, it enables nonstandard divisions such as /3, /17, and /62, making it a tool for generating glitchy, rhythmic complexity.

Design

The module uses an AVR chip with updatable firmware and includes selectable modes for Gate/Trigger output, Divide range (up to /64 via jumper), and Auto-reset, which resets the divide counter every 16, 24, or 32 clocks. Optional break-out panels expand functionality, and the firmware can be updated using manufacturer-provided instructions.

Context

The 4ms Rotating Inputs pairs with the RCD Breakout [RCDBO], Shuffling Clock Multiplier [SCM], SCM Breakout [SCMBO], and RCD Faceplate [Black]. It is part of a product family that includes the Shuffling Clock Multiplier and related breakout modules.
