I Would like to know everything I need to buy to get Cross DJ working with my MIDI controller to its full potential.
4. Is there any specific kind of USB hub I need to purchase or will any old thing get the job done!
The MixTrack takes power from iPad (battery) unless it has its own powersupply.
The datatraffic is limited for audio and MIDI. So also older type could do.
For new or old it is important that the hub provides sufficient power. the cheapest sometimes deliver just '1 port max power' in total. The best have max power to all ports.
If you have to buy consider the shape and nr of ports. Free space between ports is convenient. I would recommend 7 ports or more for multipurpose usage (only a few $$ more than 4).
