Okay, after playing around with it for a few minutes: I really like it! Great potential. It did crash (incl. Reaper) after 5 minutes, but I know that happens at such an early stage. If I were to have any input, here are some features I would find useful. It would be great to write-in your own progressions to tweak them. Also if it had a legend (more like a library of basic types) for chords and inversions. Chordpulse (there is a demo) does this very well. Anyway, that would be a huge thing for this. Also, it would be great to have a little more control of the structure. Be able to set the length of the verse, chorus, etc.. Those would be the things I might look into after the stability gets worked out. I can see this project has a bright future! Keep it up!!! :D
