Just an FYI really; I have a pal who's the sound engineer with Introducing Live, who are touring Daft Punk's Discovery and playing the lot actually live, which had never been attempted before, even by DP themselves. His main gig is writing pro music software, so he knows his waveforms. Pretty neat, so if you want to know how it's done, that's another source. Some might be interested in links. Google's easy, so here's their tube: http://www.youtube.com/user/introducinglive
