The repo contains the KiCad files for manufacturing the printed circuit board and front panel for a 4-channel Eurorack active mixer, based on the one Hagiwo assembled by hand here. This project is a simpler precursor to building a Eurorack module with a Daisy Seed, in order to hone my skills and go one-time through the PCB manufacture process.

For this design I am aiming to: - use through-hole components only - mount the pots and jacks directly onto the PCB - as opposed to just securing them to the panel and wiring each individually to the board (as in the original Hagiwo design) - place all…
