EXS 24 Logic Sampler Users Group

I originaly posted this message on the LUG, and have tested it out
some more last night and think it may simply be a low memory issue..
Any thoughts on this?  Any EXS experts out there?

  I was wondering if any members here has had success with the Maestro
  Grand GIGA file conversion? I got this file from Audioshots and it's
  pretty great sounding with the exception of sample clipping. It
  doesn't appear to be consistent on a particular note/velocity.
 
  This is a multi layered instrument across an 88 key range. I dug
  around and in the EXS manual, and determined I'd have to set 
  the cross fade and a specific amount per zone. Is this true? or the
  right approach to cleaning up this sample instrument? The issue is 
  that there are several hunderd samples!

  The Logic FAQs over at OmegaArts pointed out that I could in fact
  click the cross fade check box en mass with a lasso/key command
  sequence.. Now I'm 1/500th of the way there assuming this is the
  right approach to get this puppy to work right. Insights?

Thanks for any input!
