***Pioneer DDJ SX PERFORMANCE PAD HELP!!!***

Just wondering if anyone who has the Pioneer DDJ SX DJ controller that is using Cross has encountered problems with the performance pads? I downloaded the demo version to try it out before buying the full version, and when my controller is on with the software running, I have no problems setting cue points using the 8 pads, but thats it. I cant use the "Roll", "Slicer" and "Sampler" functions? (Nothing happens when I push them to turn on) Do I need to do something to get them to work because I use these a lot during my gigs ...Anywho, hopefully someone can help me out here because I really want to use Cross, but not being able to use these features I may have to stick with Serato
