Numark DJ/IO - output multiple channels

I’m trying to use Audacity to OUTPUT two channels to different places: a stereo channel to a mixing board (and eventually on to a PA), and a mono click track to my headphones.

I got one of these Numark DJ/IO boxes. Has anyone had any success using these with Audacity? I can get it to play just fine through the device, but it’s not splitting the channels up - I’m getting both the click and the stereo channel.

Any help with this would be appreciated! :smiley:

Audacity can’t do that. Audacity can only output to one mono or stereo device.
