105 parts, built around the 74HC595 and IRLZ44N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the locokepler/Pipe_Organ repository on GitHub, at the commit this page was made from: the board is CAD/circuts/Organ Serial to Parallel/Organ Serial to Parallel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask locokepler before reusing the design.
