new piano bringup with yet another random music

Process of bringing up new boards. No design changes. Different manufacturer. Previously I hand soldered all boards. This is the first try of PCBs with most components pre-installed.

The music in this video is me playing the piano using these new boards. Recorded after finish getting the boards and piano working. Wrote a mellow piece to go along with testing and debugging!
