Yeah man, I just found that Youtube tutorial the other week where he whacks up the release and reduces the polyphony to 1 on the NN19. I tried that shit on the NNXT and it works a treat. I'm now banging my MPD like it was an MPC and I couldn't be happier. I do sometimes have to duplicate the slices and take off the release if I want to cut the sound off before the whole slice plays out, and when laying drum tracks you need to keep the polyphony up otherwise you wont be able to play a kick & hi hat at the same time, but that's all good, Reason is definatley a tweakers tool!
Your beat sounds dope, nice and minimal (in a good way)!
Here's a beat I just knocked out the other day using those techniques:
