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.
Polyphonic is the ability to play multiple notes at the same time. Polyphonic instruments allow chords, layered harmonies, and complex musical passages, making them suitable for pads, harmonic textures, and expressive performance.
A synthesizer is an electronic instrument that generates and shapes sound using oscillators, filters, envelopes, and modulation sources. It allows sounds to be created from scratch, altered in real time, and controlled through keys, sequencers, or external controllers. Synthesizers are used to produce everything from basses and leads to pads, textures, and experimental sound design in both studio production and live performance.
Wavetable is a method of sound generation that uses a collection of digital waveforms stored in tables. It is used to create evolving and complex tones by smoothly scanning or switching between different wave shapes. For example, wavetable synthesis can be used to produce moving pads, shifting basses, or textured leads that change character over time.
