This article will explain how to broadcast your Traktor mix with Mixlr. This article is for using the Traktor S2 controller with Mac.
As the S2 has no available inputs, you will need to set up an Aggregate Device and use Mixlr AudioLink to route the audio between the S2 and Mixlr. These instructions would apply to any MIDI controller with no inputs.
Create an Aggregate Device
Go to 'Audio Midi Setup' on your Mac, which can be found here.
Create a new device by clicking the '+' icon in the bottom left-hand corner, and select 'Create Aggregate Device'.
Select to use Traktor Kontrol S2 and Mixlr AudioLink for your new aggregate device.
You may want to rename your new aggregate device to make it easier to find later.
Open Traktor Preferences
Open Traktor on your machine. You can open the Preferences window by clicking the circular icon in the top right of the app, highlighted below.
Traktor Audio Setup
Select the the Audio Setup tab in the column to the left. Ensure that the settings are as follows:

Select the aggregate device in the Mixlr app
