"...what I'm hearing is the actual drum line recorded by the song's drummer, and I'm triggering those sounds by playing notes within the designated timing window. And that timing window, even on Expert, is quite a bit more generous than real life. It's the difference between truly playing a beat and merely invoking a beat. When I play Rock Band, though, that difference is camouflaged so subtlely and so well that I never even notice. That's a beautiful bit of design, isn't it?" Yes, it is. Bill Harris on the magical quantize that you forget exists in Harmonix' games. This, incidentally, is something I'm convinced Neversoft never got right, especially in the horrendous Guitar Hero 3.
