Now that I've seen somebody cope with my lack of explanation: things above "start new song" aren't taken into account properly until you start a new song, and might make it sound weird until you do.
Oh, I think putting strum-miss chances at 50% is most interesting, should probably be the default eh?
Thanks, Jupi :)
