Free Modular
This project is an attempt to make Eurorack modular synthesis affordable and accessible to everyone.
This repository contains open source software and hardware schematics for Eurorack modules which are designed to be assembled easily and cheaply without any technical knowledge. Every module should be able to be assembled for around $20 in about an hour of work, even with limited experience.
To get started, check out some of the links below.
Happy travels on your modular journey!
