 * Basic MIDI Visualizer

 * 
 * This is a basic MIDI visualizer using addressable LEDs, to demonstrate how
 * Arduino's MIDI library works. Playing a note turns an LED on, stopping a note
 * turns the LED off. Continuous controllers 21, 22, and 23 adjust the RGB color.

 * Why use a 7 band MSGEQ7 graphic equalizer chip when you can get many times more frequency bins with software alone and on an Arduino UNO to boot?
 * 
 * This example combines high speed A/D conversion, FFT (Fast Fourier Transform) pitch detection combined with simple FastLED library display using
