Reason is one of the best tools for sampling...you can put anything in it, and you're not breakin' bread for something like an MPC. I don't get why people talk down on it. Again, the product is only as good as the person using it.
To answer your question Reid, I have no idea. But now I'm curious, 'cause I just copped Pro Tools (which came with Reason) yesterday to add to my collection of sequencing and sampling programs.
