15 parts, built around the ATTINY85-20PU. 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 interspecifics/TinySynth- repository on GitHub, at the commit this page was made from: the board is electronics/microsynth/microsynth_noeuro.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 interspecifics before reusing the design.
