README
README.mdPolytimb64 is a polyfonic midi interface to connect commodore 64 to midi keyboard by means the user port. I found this project by chance on youtube https://www.youtube.com/watch?v=LIM-qxfz80c The author have made a full and comprensive guide to to build the hardware and how to use the c64 software https://notevoto.4lima.de/PolyTimb64_Main_EN.html In this repository I would share a custom PCB that in addiction to the original hardware implement a little oled display and a a midi thru connector
I'm not a musician but the softwre is very powerfull with many setting like pulse width, filter and pich modulation

Questions
How big is the PolyTimb64 PCB?
It measures 48.5 × 80.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PolyTimb64 use?
22 parts. 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 PolyTimb64 KiCad files?
From the matt199394/polytimb64_pcb repository on GitHub, at the commit this page was made from: the board is polyTimb64/polyTimb64.kicad_pcb and its schematic polyTimb64/polyTimb64.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PolyTimb64 design in my own project?
Its repository states no licence, so its author keeps all rights: ask matt199394 before reusing the design.
