Okay, Theatrhythmites. I need some help here.
Does anyone know the specifications for triggering which of the three bosses show up at the end of the Dark Note BMS? I've replayed the first Dark Note I was given seven times so far, earning all the shards from Boss 3, but not even getting Boss 2 to appear and stumbling upon Boss 1 once, but not doing well enough to get anything to drop. Is it just random or do you need all critical hits? During the FMS part, I am able to quickly glance a sign on the top screen that says something about "this way to the boss <--" but am too busy tapping for my life to grok it.
