Hey, the scales are just an array of numbers like this

    ['Darkness', [0, 1, 3]],
    ['Darkness2', [0, 1]],
    ['Single', [3]],
    ['Locrian', [0, 1, 3, 5, 6, 8, 10]],
    ['Aeolian', [0, 2, 3, 5, 7, 8, 10]],
    ['Mixolydian', [0, 2, 4, 5, 7, 9, 10]],
    ...

So if you had the 'Darkness' scale selected and had the root dropdown set to 0, the notes in this scale would be C, C#, D# which is 0, 1, 3 if you count the keys on a keyboard. If you changed the root to 2, then it would become D, D#, F (2, 3, 5).

Hope that makes sense.

That does make sense, thanks! Very simple and effective.
