hoping its not the cdj cause it was brand new i just got them 2 days ago...


Close System Preferences.

Open /Applications/Utilities/ and launch Audio/MIDI Setup.

You should be able to configure them using this utility.

Also the quick setup, and manual have examples of cable setups and MIDI, and Audio software configurations that you could potentially use. You can get those here:

Let me know if you have any questions.

Yours sincerely,
