Reply to HELP! Xone dx

Hey guys,

Jus bought a A&H Xone DX yesterday evening from guitar center for 600. gota say, i kinda jumped the gun when i bought this, but I've been keyboard DJ'in (pathetic)for 3 yrs now and I'm SICK OF IT!!! hooked it up and started to play around with it....and got sum questions...For starters, I only know Traktor 2 and haven't ever messed around with Serato Itch.

1) how in da hell do you turn off the other 2 decks? it takes up ALOT of screen space and i hate to see empty decks. also, is their any way to make the wave form bigger like in traktor so i can see my breakdowns, base lines and cue points clearly?
2) i noticed that you cant hook up an external midi controller like a midi fighter...is their any way that i can get around this so i can use a midi fighter with this controller? do i need to buy a Traktor kontrol box or can i hook it up to my computer directly through another USB port to control samples?
3) i eventually want to hook up turntables to the xone dx. do i need serato scratch, or can i buy traktor scratch pro and use this controller as a mixer with x2 turntables for controlling the deck? the "jog wheel" on this thing suck A$$!!
4) and finally, :P since i love traktor so much, anyone got any good mappings that i can use to interface the xone dx with traktor smoothly? also anyone know where i can DL advanced mappings in terms of power knobs like the one shown here in YUL303's DX traktor youtube videos...this guy is fukkin amazin!

Sorry for the long read....
Thanks for all the help guys!
