Having a DTExpress II I can make my own loops, not difficult as I just record the Midi out using Sonar. I can then quantize, loop, add fills (either in real time or as individual hits using midi and Im good to go !

If I use Sonar I can then alter tempo / assigned sound and it is just cool !

I may have a hunt for some cymbal samples as a set or real cymbals is hard to attenuate !! SO any advice you have would be good there !
