I was telling my wife last year that I should create a keyboard for Rockband. Looks like someone snuck in my brain, and beat me to it. Just announced at e3 today, the newest installment of Rockband will include the usual instruments(although all newly designed), with the addition of a 25 key keyboard that also doubles as a midi controller. The game supports up to 3 singers. You can learn serious skills with Rock Band Pro. Rock Band "Pro" requires the use of brand new hardware. The Pro guitar is a six-"string," 17-fret axe that has sensors at every position. This means actual notes and chords show up on the expanded note highway that kind of looks like mobile guitar tablature. The keyboard version is also a lot more complicated than the regular game. Trust me, it's for your own good.
