Use a the same time the computer built-in sound card and the DJ controller audio in Mac OS

When the DJ software audio setup menu lets you select 1 audio device while you wish to use 2 sound cards simultaneously, the solution in Mac OS is aggregating devices.
The aggregate device is 1 virtual sound card aggregating 2 (or more) sound cards.

Here is an example to play
- the mix on the Mac built-in sound card
- the preview on the headphones output of the DJ controller Universal DJ
- in Djuced 40 3.1.0, in Mac OS 10.10 (Yosemite).

1) Connect your DJ Controller to the Mac computer.

2) Set your 2 sound cards at the same sampling rate
- In Mac OS top bar, go to Go > Utilities
- Run Audio MIDI Setup
- If you don't come directly to the Audio Devices menu, go to Window > Show Audio Devices
- Select your DJ Controller, check its audio format, for example 44100 Hz with Hercules Universal DJ


- Select Built-in Output, make sure the audio format is the same as in your DJ controller, 44100Hz (=44.1kHz)



3) Create an aggregate device
- at the left bottom corner of the Audio Devices window, you have a + sign: click on it, and select "Create Aggregate Device"

- You can let it called "Aggregate Device" or give to this device the name you want, for example " Aggregate - Computer & Universal"
- In the list of audio devices included in the Aggregate device, check in the Use column the 2 audio devices "Built-in Output" and Hercules Universal DJ

Leave Audio MIDI Setup.

4) Run Djuced 40
- Go to the Settings: click on the gear wheel on the right top corner

 - you reach the audio settings menu
  in Audio Device, select the name of your aggregate device
  in Master field, select Output 1&2
  in the headphones field, select Output 5&6 


Click on OK. In Djuced 40, you now play
- the mix on your computer built-in sound card,
- the preview in the headphones output of your Universal DJ.
