  13 // DESCRIPTION:
  14 // Demo sketch to play notes from middle C in the 4th octave up to B in the 5th octave and then back down.
  15 //
  16 //
  17 // HOOK-UP:
  18 // 1. Plug USB cable from Arduino into your computer.
  19 //
  20 //
  21 // USAGE:
  22 // 1. Install and Set-up Serial MIDI Converter from SpikenzieLabs
  23 // 2. Open, compile, and upload this sketch into your Arduino.
  24 // 3. Run Serial MIDI Converter in the background.
  25 // 4. Launch your music software such as Garage Band or Ableton Live, choose a software instrument and listen to the music.
