4ms Modules
Eurorack modules from 4ms Company known for experimental design and ping-based clocking
Overview
4ms Company builds compact, concept-driven Eurorack modules that often blur functional categories—like the DLD, which offers two channels of clock-synced looping delay capable of holding at least three minutes of audio. The Ensemble Oscillator takes an "unorthodox approach to synthesis" using 16 sine-based oscillators to enable additive synthesis with user-defined scales. The Atoner, sold as a kit for $125 or pre-assembled for $275, is described as hijacking and distorting note timing rather than playing traditional sequences. The EnvVCA, released in 2023, is a svelte 8HP analog module combining envelope, LFO, and VCA functions with a clean exponential response. The Rotating Clock Divider, available since 2012, dynamically rotates clock divisions across eight outputs, making it a flexible tool for rhythmic variation.
Design
Some 4ms modules utilize the +5V power rail to reduce load on standard Eurorack supplies. The concept of a "Ping" input—used to sync or trigger behavior—is a recurring design element across multiple modules, suggesting a unified timing philosophy. Firmware plays a role in functionality, as seen in the DLD, where version can be checked via a system menu, and source code is publicly hosted on GitHub.
Market
The Ensemble Oscillator launched at $299, while the Atoner was priced at $125 as a kit and $275 assembled. User reports indicate occasional boot issues with the DLD, though it has been recommended by players for its performance. The MetaModule, designed to run VCV Rack plugins in hardware, was noted in 2024 as a platform for building custom synths or effects, but no pricing or availability details are confirmed.
