PC/Mac & DJ Software

I can't control rekordbox.

Will support for Traktor become available?

Can I connect the unit to my PC/Mac using a USB hub?

Can I use this unit without an internet connection?

What's the best process for connecting to a DJ application?

I want to connect multiple CDJ-3000 units with my PC/Mac to use them as audio interfaces. How do I prepare to do this?

What features are available when I connect my PC/Mac to the unit via a USB cable?
