Expanding TONS of Switches/LEDs with Arduino (Teensy + ATtiny) and Controlling over MIDI!

Big thanks to this customer for giving permission to showcase this project here - lots to discuss and hopefully you'll pick something up here to use in your own projects! TLDR: Expanding IO from a Teensy 4.1 over I2C bus using ATtiny1614's super easy to do this and the MIDI control from the Teensy keeps it simple.
