MIDI controlled LED strip - Part 3, digital piano

I got a digital piano (Yamaha P125b) connected to a WS2812b (neopixel) strip of RGB LEDs. The piano is connected to a computer using USB, and the computer outputs MIDI through a USB to MIDI interface which connects to the LED Strip interface. The computer is running MIDIOX These demos were possible after a bunch of bug fixes and a major code rewrite, but all is well now. The code will serve as the foundation for future versions, where we can make more complicated and interesting patterns.
