Just to be really clear though - you can't run three physical turntables and run three vitual decks.

You can run 2 physical turntables, and they can control 3 virtual decks, or you can control any of the decks using a controller or the laptop. So the FS guys were kinda right, but stupid all the same, because with traktor 3 it can be done.

Because you get to set which physical turntable controls which virtual deck you can switch about really quickly and easily. Hence the ability to run three virtual decks with one physical deck if you wanted to.
