PLEASE READ THE INSTRUCTIONS: - Select the root note from C to B - Choose the tonal change; flat, natural, or sharp - Choose the build of the chord, I know it isn't very systematic but it's good enough when the project is small like this. - Use the 6 small black buttons to configure custom chord buttons. The preset chords are for the song 'Gypsy Woman'. TURBOWARP for high quality pen and higher FPS: https://turbowarp.org/1048535357/fullscreen?hqpen&fps=250
