Questions

How big is the Final session split2 PCB?

It measures 160 × 71.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Final session split2 use?

79 parts, built around the TL072, BC547 and BC557. 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.

Where can I download the Final session split2 KiCad files?

From the microresearch/notes repository on GitHub, at the commit this page was made from: the board is final_session/finalsessioneurorack/final_session_split2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Final session split2 design in my own project?

Its repository states no licence, so its author keeps all rights: ask microresearch before reusing the design.
