Bought this to 4 deck mix while sat on the sofa but was bigger than I thought ( yes u can 4 deck mix as it's got buttons to swap channel to 3 and 4) , so went with a wego as u can do it on the early models as well ....... It does work with rekordbox but if u haven't already got an unlock device u will have to pay subscription ......... But works on other software as well ........ It's actually in very good condition so u should be well chuffed , box is battered tho as u can see in the photos ........
