Synthwerks is a Seattle, Washington-based maker of Eurorack-format synthesizer modules, founded by James Husted and Steve Turnidge. The company focuses on performance-oriented and special-purpose utility modules designed to give synthesists more expressive, hands-on control than traditional control voltage keyboards typically allow.

The brand is best known for its line of Force Sensing Resistor (FSR) modules, including the single-channel FSR-1N, the FSR-1T, and the four-channel FSR-4, which translate finger pressure into pressure CV and threshold-dependent gate signals. Other notable modules include the MG-1, an arcade-button manual gate that routes signals between inputs and outputs, the PGM-4X4 programmer, the SP-4DP, and the Lamp-1.

The founders bring a long electronics pedigree to the company: Turnidge spent over a decade at Rane Corporation and had long envisioned building performance modules for pro audio, while Husted's background includes extensive work with EMS Synthi AKS synthesizers and joystick-based abstract sound design.

Synthwerks has 2 products cataloged on Equipboard, including Modular Synthesizers. Their gear is featured by 2 artists, with the strongest followings in Electronic. Notable users include Deadmau5 and Richard Devine.
