Was wondering. I just upgraded my mixer to the Pioneer DJM-900, I was using Traktor Scratch Pro as my DVS system, but no longer will be using the box since my DJM can be used as the sound card. Which upgrade option do I need to get to upgrade to Traktor 2? I already have my timecode records and cds. Do I now need to upgrade just my software from TSP1 to TSP2? or Uninstall TSP1 and Purchase TSP2? or last but not least Purchase TSP2 Certified Upgrade since I have a TS Certified mixer? Thanks in advance! Just saw this. http://www.native-instruments.com/#/en/products/dj/traktor-scratch-pro-2/?page=2008 Hmmmmm so is it going to cost me 79$ or 339$?
