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. | |
