About
Inspired by my love for music and DJing I have decided to design a midi controller to enhance the software I use. The controller has 64 buttons and 4 faders and is controlled by an arduino style pro micro with 4 multiplexers.

Questions
How big is the Midi PCB?
It measures 193 × 204 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Midi use?
86 parts, built around the CD74HC4067SM96. 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 Midi KiCad files?
From the Max-Worboys/midi-controller repository on GitHub, at the commit this page was made from: the board is PCB Stuff/midi.kicad_pcb and its schematic PCB Stuff/midi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Midi design in my own project?
Its repository states no licence, so its author keeps all rights: ask Max-Worboys before reusing the design.
