Must be something to do with having the control leads hooked up that you get with the players. There is no way it can send that info through the red/white cables, so try hooking the control leads up. They enable the fader start to be used, and it may just make that work as well. However it may also require the 900 mixer, not sure. And yer, seeing a proper vinyl set was dope, I'd never seen anyone mix real vinyl before so that was real cool to watch.
