Numark iDj2

Hi Guys - I just got this Old Numark iDj2 system and I want to use it with Iphone/Ipad.
What app should I download?
So will it be a plug and play solution?
Should I connect iphone/ipad to one of the USB ports?
How can I connect my Macbook pro?

Sorry, so many questions :slight_smile: Any help will be appreciated.
