BTW, if they have 1000's you cant hook them up to Traktor via usb cords, a timecode set up is needed. If the club has 900's/2000's than why not let him play off Traktor and you take 2 UBS sticks and plug them into the decks and you can play off USB sticks. This ^ it isn't compulsory to use recordbox to analyse files either, you can just make folders and copy the files on. Just make sure you format the sticks to fat32 first
