I was able to successfully update one of my cakes. When I tried to update the second, on the reboot it got as far as the blank white screen and has just hung there. I've tried unplugging and replugging it, but it all it does on powerup is go to the blank white screen.

Is there a way to fix a scale so that any chord I choose will be within that scale? (For example, D Dorian, so that if I push F it will be F major, D will be D minor etc.)

I'm having so much fun that I bought a second, so I can have even more complicated arrangements.
