I guess the drawback of an iPad for the serious dj is lack of storage. It’s ok if you’re doing one Dj slot every 17 years and you pretty know already what you’re going to spin.
are they the nexus cdjs and are you using ethernet or usb? im just trying to work out which software to use as a library with my xdj 1000s(digi only and mostly the same as the nexus inside) as controllers and its not clear if usb or ethernet works best/easiest with this series of decks and it seemed logical on the surface to use recordboxAt home I use 2 pioneer decks networked with a pioneer mixer all linked to computer running rekordbox. I can play tracks on the cdjs straight from rekordbox without having to load USB sticks
