Hi @roco50, unfortunately the Numark iDJ Pro is no longer on our list of officially supported hardware for iOS. This controller is quite old now and was originally designed to work with djay Pro 2 which is no longer supported or available unless you previously purchased it years ago. Also the iDJ Pro uses an old 30 pin connector so you will need an adapter to make it work with a new iPad and the overall fit could be an issue depending on your iPad model.
Please see below for our list of officially supported hardware for djay Pro 5 on iOS:
There is some additional discussion about this controller in another topic as well:
