From the project

Prompt-driven design of Eurorack modules with KiCad 10

Prompt-driven design of a Eurorack instrument, played in VCV Rack before it is built in hardware. Build digital versions of the proposed modules, try real patches, and learn whether the instrument has a useful balance of VCAs, LFOs, envelopes, voices and utilities before committing to physical designs.

The existing hardware toolchain is retained: modules are described in Haskell, KiCad projects are generated from those descriptions, and KiCad's command-line tools verify them and produce the files JLCPCB needs. The KiCad GUI is a viewer, not an editor. Hardware work resumes after the musical…
