Eurorack Synthesizers
All firmwares available on every module.
Echoa
Four delay lines, two per stereo channel. Morph delay into reverb from first principles — clean digital echo to smeared, textured reflections. Series, parallel, isolated, or spectral routing. Presets and parameter lock on every pot.
Spagyros
Nine effects tailored for performance. Layer up to three at once to build, drop, beat repeat, vinyl break, and more. End-of-chain FX, built for performance and sound design alike.
Introducing
Hermetic Modular is a new boutique Eurorack synthesizer manufacturer based in Seattle, Cascadia.
01
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.
02
We design for live performance; that means balancing compactness and portability against knob-per-function immediacy. This balancing act is the guiding star of all hardware designs.
03
Every release strives to be long-lived, extendable, repairable, and open. That means expansion ports, SDKs, top of the line digital chips, and easily repairable daughter boards.
