these days I do all my remix stuff in Logic on a Mac. It's just easier to use that EXS24 sampler than Reason or other stuff, which I used to use.
Basically you just drop it in, tune it, loop if desired, and save as a new instrument.
I use Ultrabeat for the drum samples since it automaps it to keys. I prefer to live play on OHCs if possible since I'm better at that.
