We’ve stated many times that Rock Band supports an open standard. What does that mean? It means that Rock Band supports the same system that drives a basic PS3 or Xbox 360 controller or peripheral.
If your controller or peripheral doesn’t work with Rock Band, it is because the manufacturer doesn’t support the standard controller configuration. In other words, if a peripheral or controller doesn’t work with Rock Band, then the manufacturer has done something to prevent it from working with Rock Band by changing how the device “talks” to either a PS3 or Xbox 360.
If any controller or peripheral manufacturer wants their product to work with Rock Band, we promise to work with them to create a patch or adapter to make it work.
We also want you to know that we are working to get stand-alone Rock Band Guitars, Drums and Microphones to the market as soon as possible. In addition to rounding out the band with a second guitar, Rock Band supports guitar vs. guitar, drum vs. drum and vocal vs. vocal modes.
We want you to enjoy Rock Band and have set up a superior customer service program. If you have any concerns about Rock Band, please visit: http://support.ea.com/rockband
