Hey guys sorry about the annoying newbie questions but I'm getting confused about what software I actually have and its capabilities. To keep a long story as short as possible I bought a job lot of stuff from a DJ who was selling his old gear, in this bundle I got the Audio 4 DJ soundcard and a copy of Traktor that came bundled with the 4trak controller. I want to know whether this is enough to run a DVS system or whether I need to buy Traktor Scratch? also If I do is there any way to buy the software itself as I keep seeing it just as part of a bundle? Any help is much appreciated!! Cheers Scott.
