As you can see in this japanese video the DJ’s are controling multiple audio and video effects just with a Wii video game control, which is designed to recognize movement in all directions, apparently they are using Max/MSP/Jitter external software for Mac, maybe it could be freakish, but at the same time it improves the experience using new tools for live acts, performers or DJ’s, through time, new technology grows along with music, so new technology is always going to mean new music, in fact on the near future you will see music applications designed for multi-touch screens… imagine this revolutionary technology with this kind of software.
