And again: this is utterly weird.  If the sample editor plays back 
the sample correctly, so should the EXS...

It *is* the same thing.  The 'aif' or 'aiff' is just a file extension 
(like in DOS) and has nothing to do with the actual format of the 
sample.

It might be something like a format-problem...  Maybe the Sample 
Editor recognizes filetypes by their actual content while the EXS 
trusts the file extension, which in some cases might be wrong.  This 
would be completely stupid, but I can't think of anything else...
I wonder what happens if you would do this: take some of the 
noise-causing samples and use some 3rd party sample editor/converter 
to convert the files to aiff format (yes, I know they're already 
supposed to be aiff's, but maybe there's something wrong with the 
format -- header info or whatever).  Just try with one or two: open 
in some conversion program, check to see if they sound okay, and then 
save as aiff with another name.  Now create a new EXS instrument 
using those samples.

If that works okay, there's a format-problem somehow. You should then 
simply batch-convert all offending samples and save them under the 
same (old) name.  Throw out (or stuff or zip, for safety's sake) the 
old samples and the noise-instrument should now automatically find 
the new samples and should sound right.
If conversion does _not_ work... well, I might have thought of 
something else by the time you've tried this :-).
