EXS 24 Logic Sampler Users Group

Hi - 
1) We have 10 registered EXS copies at our training program, so 
this isn't one of "those" posts... but: where is all the info about 
EXS-Mk2 consolidated.? We got these flimsy version 1 manuals.  
Then there is an AppleGuide for v.1 also (not very helpful).  Then 
there is the upgrade pdf which discusses changes (helpful).  I 
seem to remember there being a guide to the EXS in the Logic 
Platinum help file, but there's nothing there except a What's New 
section or softsynths.  Am I missing something?

2) Missing a consoldated currrent manual, can someone give a 
brief explanation of the functionality of the "Select By" options in 
the Group Editor (options are: Note, Group, Cntrl, Bend).  Thanks
