Open-source Eurorack modules, forged in code and copper.

Voltage Foundry Modular designs and builds open-source Eurorack modules. Every one is real, buildable hardware, and the firmware-driven ones also ship as pixel-accurate VCV Rack plugins — the same firmware that runs on the metal runs inside Rack, so you can try them before you buy or build.

Blank Panel - 4hp, ClockForge, NoteForge, GravityForge and Blank Panel - 1hp are among Voltage Foundry Modulars most popular products.
