Numark introduced their new controller the Orbit at NAMM 2013 and I have to say that I'm not sure what to think. I like the idea of a DJ not being locked behind the decks and be able to run around and pump up the crowd, but not looking like you're playing a Playstation game. Somehow I probably would try this if the latency is low. Got to love wireless gadgets.
Would you use it?
Some times it's OK to let the computer do the work.
I use this function when the club opens and there isn't that much guests/customers around.
The tutorial from DJ TechTools is a pretty nice run-through on how to use this feature to the fullest.
