EXS 24 Logic Sampler Users Group

I'm new to the ESX24 (thanks to those that helped me get it working 
correctly!).  A comment, then two questions:

I went to the Los Angeles "Emagic Essentials" tour on 10/29/02 (West 
LA music).  I found it very interesting.  They demonstrated the 
ability to load REX files and then randomize them in the Transformer 
(very cool).  This same thing tip is in Keyboard Mag this month.  I'd 
suggest for those that haven't seen this neat trick to give it a 
try.  For me, it has really spiced up a few tracks.

I know that there are CDROM's out there that have REX files on them 
(I know this because I bought one this weekend to test on to load and 
use a REX file!).  Now the first question - any reccommendations for 
REX file CDROM's for drums?  I'd be happy with a hip-hop, R&B or rock 
style (a jazz style would be very helpful too).

The other question is: What is a very good piano sample that can be 
loaded into the ESX24?
