Fretless fader prototype

It's going to be kind of hard to understand what's going on here if you haven't used DJ gear before, but if you have, you had better be sitting down. In short, the crossfader is placed into a vertical fader that is apparently sending pitch control to the turntable. This is bananas - the kind of next-level technology that a short time ago would have been the stuff of science fiction.
