This was written for the BluePill board with a W5500 SPI Ethernet adapter although it does work on other boards such as the Adafruit Feather M0 and M4 boards. You can find my sketch here: https://github.c...

It sounds like we have similar interests, I am using GrandOrgue and have designed and built Keyboard, Stop and Piston controller boards which use BluePill daughter boards. I'm linking Multiple Keyboard scanner boards via I2C bus over ribbon cable to a master board that sends Midi messages over UDP M...
