hey,
please register your software to get support.
But two little information: Cross (DJ also) can work with nearly every MIDI controler but most of them you have to map yourself.
Second information: Cross currently have NO sampler it will be in the future but when I can't say so stay tuned it will be this year (I hope 

 because many peaple wants this feature 
 
   
  
 )
so I hope this helps you but no more help without registration 
 
 regards
Christian
