Apple Logic Pro /LogicExpress Discussion

Hi I have a zip disk full of samples that I used in my MPC 2000xl.  I copied them onto my 
mac using a usb zip drive.  However, now I have them on my mac, I'm trying to get them 
into the EXS sampler.  The mac won't read the file format.  They are all in .SND format.  Is 
there a way to convert it? If so which software should I use?  Cuz Logic, Quicktime, iTunes 
won't do it.

I read other forum entries on Akai conversions, but they didn't seem to apply to this 
situation.

I'd appreciate any help anyone can give on this.

Thanks

Sel.
