Guy demonstrates the editing capabilities in the new Guitar Hero game, Guitar Hero: World Tour. For example, the guy drums a beat into the game which is recorded. He then plays it back and has a button to omit certain bits. He can even change the volume of the drumming by changing the position of the guitar. Another feature is playing it back in a different way, which he shows with the drumming played back in a gaming/techno/trance sort of sound.

The game is set to come out very soon, so what better way to see what you like that to watch this video!

Being released onto the main consoles, it looks to be big.
