Emax

So I watched the "in the studio" with Lifelike from a recent issue of Future Music.  He goes over how he is using the Emax with Alchemy and shows the stereo sample trick panning the primary and secondary layers on a preset, pretty neat.  But I'm having a hard time wrapping my head around the way in which he got the stereo sample into the Mac to begin with.  So, how would one go about getting a stereo sample into Alchemy?
