What sort of settings should I make to use multiple CDJs as sound devices on a Mac computer?

To use multiple CDJs as audio output devices on Mac OS X, you must create a "device set" using "Audio MIDI Settings" included with the Mac computer and make the required settings.

-For Mac OS X 10.5.X

With all CDJs to be used connected by USB, launch "Audio MIDI Settings" in the Applications:Utilities folder.

From the "Audio" menu, select "Device Set Editor". Next, click "+" on the device set editor screen to add a new device set.

Click the added device set to select it, then add the required number of CDJs to that device set.

-For Mac OS X 10.6.X

With all CDJs to be used connected by USB, launch "Audio MIDI Settings" in the Applications:Utilities folder.

Next, click "+" on the "Audio Installation" window to add a new device set.

Click the added device set to select it, then add the required number of CDJs to that device set.

After creating the device set, select this device set in the sound output device settings of your DJ software.
