Hermetic Modular

Hermetic Modular is a boutique Eurorack synthesizer manufacturer based in Seattle, Cascadia.

Every hardware release includes an open firmware layer with a permissive (MIT) license and a powerful SDK that lowers the barrier from DSP to embedded programming. Modules feature field-programmable jacks, enabling circuits to be changed in real time. We want modules to be extended, hacked, and making music in ways that surprise us.
