EXS 24 Logic Sampler Users Group

Hello.  I have a couple of Eric Persing's Groove Control discs from 
Spectrasonics.  Up to now, I've been using the Akai/E-mu edition on E-
mu samplers.  Now that I have Logic and EXS, I'd like to convert them 
over.

Would I use the options button and convert all of the Akai sample 
files?  And all the MIDI files?  Naturally, I want the ability to 
control the tempo, but I've never done it with the Akai version (let 
alone EXS) and I know it doesn't work quite the way the E-mu version 
does.

Any help would be highly appreciated...please and thank-you.
