This is a fun tool. It took me a minute to realise how to add chords as I though the chord root part was talking about the key or something.
I found a bug: for one of the generated progressions it had 4 chords but played multiple chords at the same time. Progression was G9, Am11, D13, Bm9. But it played G9 and Am11 at once, the D13 and Bm9 at once and cycled between these two states. Clicking stop and play again and it plays normally.
