Glitches using Rock Revolution drums on 360

[ddp72984]

my brother needed a new drumset for GH, so Best Buy had the Rock Revolution set for 30. The drums look cool, but there is a weird effect. When he hits the green pad, it activates the yellow one as well. This effect happens for both Rock Revolution and Guitar Hero World Tour (with GHWT, it randomly switches between 4 pad mode and 6 pad mode/with the cymbals) I went back to the store to switch them out, but the second pair do the exact same thing. Is this a glitch or are the drums busted? Thanks

you should download title update for guitar hero, you need to be connected to live to do so naturally.
it will help.

I'm guessing the drums might suck since the game does. Do they? My god that game sucks, lol. At least it was a budget game. But yeah, the patch might help.
