Dear God, don't get the DJX expecting to use it as a sampler. It is not a very good samples and your results won't be crisp at all.
Don't get me wrong, the DJX is very cool -- vist
http://www.abstractreality.com/djx and get my STUDIOWARE PANEL -- if you use Cakewalk, it will give you complete control over the keyboard so you can use it in a more professional environment...
It has some great preset sounds and decent drum sets... It's sampling just isn't very good. You'd be a LOT better off using an Awe64 or SB live - much more powerful sampling, better sound quality, and it's still inexpensive.
