I have never played a Rock Band game in my life (the plastic instruments didn't appeal to me), but I loved Frequency on PS2. I'm looking forward to Blitz cause it seems more accessible for me.
I own a PS3, but don't own any previous Rock Band titles or instruments. I was wondering... How can I export songs from Rock Band 1, 2, and 3 to Blitz? I'm assuming I will need to buy those games and if that's the case, I'm willing to do so. But will I need to use an instrument to control through the game menus (Rock Band 1-3) in order to export? I hope not, because I'm not willing to buy the instruments.
P.S. I see an "export key" available for Rock Band on PSN, but no DLC for Rock Band II at all, and no export key for Rock Band 3.
