Fellhorn is an open-source DIY Eurorack module created for adventurous modular enthusiasts who enjoy building instruments and exploring new sounds.
Designed as a hands-on kit, Fellhorn brings electronics, programming, and creative sound design together. The project is non-commercial and will be shared openly, allowing builders to assemble the module, understand how it works, and adapt it to their own ideas.
Development is still underway, with pulsar synthesis planned as the first synthesis algorithm. More sounds, technical details, and build information will be shared as the project progresses.
