Brand
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.

Eurorack is a modular synthesis format with standardised dimensions, power connections, and signal levels. Eurorack systems are built from individual modules mounted in cases, allowing users to create highly customisable instruments tailored to specific sound design and performance needs.
New Gear is unused and in original condition, supplied as it leaves the manufacturer. It is chosen for guaranteed reliability, full functionality, and the assurance of manufacturer support. For example, buying new ensures access to the latest design revisions, included accessories, and official warranty coverage.
Stereo is a two-channel sound format that uses separate left and right signals to create a sense of width and space. It is used to place sounds across the listening field, making music feel more immersive and detailed. For example, a stereo synth or effect can spread a pad or texture across both channels, giving a track greater depth and separation compared to a mono signal.
