In this video featuring Alex from MadCatz, we get a detailed run through of the new peripherals currently slated for release at launch with Rock Band 3. While there are no ground-breaking details that we’ve been dying to know, he does go into further detail on the keyboard and Mustang guitar.
He mentions that the handle of the keyboard not only has an overdrive button, but also a touch sensitive expressions bar, which acts like the whammy bar on the guitars. He also notes that the Mustang guitar has a touch sensitive palm muting box, allowing you to cutoff notes while playing by pressing down on the box.
One thing to note is that in his discussion of the MIDI controller box, it has a toggle for drums, keyboard, and guitar. While we’ve been hearing reports that MIDI capable guitars are not currently planned to be compatible with Rock Band 3 Pro-mode, there is still an option to plug them in to the game. While the game is designed for usage with the Mustang and Squier guitars, those holding out on using their own MIDI guitars in Rock Band 3 may not want to give up hope yet.
