Ableton Live + Novation Launchpad = Epic Live Performance Mashup :)
Also Create Digital Music blog brings some valid points about this:
If you aren’t necessarily into pop samples, though, I think this shows that even some simple performance elements can appeal. Sure, we love far-out interfaces and big visual impact around these parts, but you can also simply turn off that bar-long quantization or whip out your instrument of choice – keys, strings, voice, pads, or whatever it is – and actually play. Most people really get and appreciate that, and it’s fun for the player, to boot.
Amazing stuff. I also love one comment about it: "Oops, I think someone just figured out how Daft Punk produced it’s first two albums." ;)
ps. I need to start using my Launchpad :)
