It does make sense. It is possible in recording studios at this very moment. Just wait until it starts happening in a live atmosphere. All it would take is for the drummer to initiate the process. Everyone else follows along. I could easily see it happening, if it isn't already. Didn't Dave Grohl ALREADY slam Linkin Park years ago for using a click track or something as it is during live shows? I didn't agree with him then, but now I might reconsider.
Of course, I'm assuming that you know that during a live performance, the feedback is usually going through a mixer/soundboard. Routing through a computer device to match up to a certain time sync would allow that to happen before it reaches to the point of what the audience hears. That's what is happening with Chester's current pitch correction, essentially. His raw vocals are going through the microphone and into a pedal, which gets pitch corrected through there into what is most likely into a mixer where effects are added on top of it and into the PA system. Of course, I don't know Linkin Park's initial sound setup. That is where your ol' pal Astat would be more familiar because I do not follow them that closely as much as I used to. I'm just giving you a general idea of where it would not be impossible.
No need for the insults, man! I'm trying to be civilized here!
Anyways, it doesn't matter guys. I didn't realize everyone was going to be moody about an opinion. It's whatever. Chester is making lots of $$$ and I am not.
I don't care past my initial gripe.
