Reply to DDM4000 w/ Traktor Output Question

Hey,
I'm brand new to the community s and not completely sure if this question is being posted in the right area. Anyways, I've just got a ddm4000 and have mapped it as a midi controller with Traktor Pro 1.2. After I got through with all my mapping, I went out to my garage to hook up to the PA and realized I was getting no output. I am very inexperienced with using midi controllers, but isn't it possible to use the ddm4000 as a soundcard in a way? Is it possible to have the ddm controlling traktor and outputting sound at the same time?
Thanks,
