Do, Jesus, them beats are thick...
I have to say that I find the "build a beat on my MPC-500 live in front of an audience" trend to be somewhat tedious, although there are examples of that particular craft that show exemplary musicianship, I'll certainly admit. I just don't usually care for the music.
That said, I was blundering about the Interwebs this morning, and came across this site. You're probably aware already if you find this sort of thing interesting, but if you aren't, of particular note is the "Videos" page. The guy that runs the site, Moldover (personal site), has a 15-odd minute explanation of what he's doing that makes assembling a song in Nuendo look like child's play. While this is definitely some sort of uber-DJ thing, and of questionable merit except in a live scenario (sometimes I just want to hear the damn song, right? Not a sped-up, chopped-up iteration of it played along with 15 other songs) it certainly takes a not-inconsiderable amount of technical skill to pull off.
The other videos are interesting, as well. Particularly the stuff from Materia Prima (Youtube page here, video above.) This dude has made an absolutely sick controller... uh... thing. He, unlike Moldover, actually _plays_ a lot of stuff live. It's kind of hard to describe; you'll just have to watch a couple of the videos.
But all that by way of saying that it's nice to see someone actually getting use out of a Novation Remote. I sure haven't managed yet.
