Q: What are the daily event maps?
Q: How do I get girls with 3 or 4 stars?
A: You'll need to save up the Sound/Note Crystals to obtain them. Note that they have a very low drop rate, and there are cases where you didn't get 3-star girls at all.
You are also given a choice between 3, 3 star Orchestra Members and given one random one for free upon starting the game. You are also awarded one 3 star for completing the first set of panel missions.
