4MS

4ms is a US modular synth manufacturer best known for pushing the boundaries of timing, control, and system-scale thinking in Eurorack. The brand grew out of a fascination with clocks, rhythms, and synchronisation, and that DNA still runs through everything they make — from precision clocking and sequencing to complex modulation and power distribution.

What sets 4ms apart is how their modules often feel like infrastructure as much as instruments. Many designs are expandable, configurable, and built to grow with your system, making them favourites in large, experimental, or performance-focused racks. Whether you’re exploring generative music, polyrhythms, or building a deeply interconnected modular setup, 4ms gear is known for its originality, robustness, and unapologetically modular mindset.
