TIP: in order to set up your audio you’ll first need to set up a live event. To find out how to set up an event click here.
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.
