Welcome to Gaia! ::

Anyone who checks this thread can ask me about the game and I can answer anything, such as The songs,outfits,DLC,Minigames,and so on.

Your playing PD1 definatly.
The thing is the reason why this is is because each song is meant for a certain vocaloid - about 3 or 4 have alternate versions(I.E Rin or Len) in Project Diva. Otherwise,if your using edit mode, you can make songs that feature Rin's,Len's,Meiko's,etc voices. If thats the case its a different default character youll need. Otherwise, in PD2, Since some songs have the ability to have 2 vocaloids, some of the default team ups youll see is Miku and Luka(magnet), Rin and Len(Gemini), or Rin and Miku(Forgot the name of the song this uses. sweatdrop ) If thats the case, then whomever is playing in those roles will sing with that voice (So if you play Rin and Len on Magnet,Rin will have Miku's voice and Len will use Luka's).
So yeah. Next question?
