EXS 24 Logic Sampler Users Group

I just tried CDXtract with the hope of converting
many of my roland libraries to EXS format.  They claim to have the 
original Roland de-emphasis algorithm available in the software.  I 
just tried a Hans Zimmer guitars vol 1 disc.  conversion process 
itself went fine.  I now have the converted one right up against the 
S760.  The listening comparison is horrible.  The converted file is
considerably more dull and flat sounding, while the original is much 
more open sounding (i'm monitoring the EXS digitally into a Mackie 
D8B via an 888, the S760 is going analog into the D8B).  Also i'm 
noticing an audible click at the beginning of each keystroke right at 
the top of the sound starting - almost like a non-zero cross point 
butt splice sound.
 
the latency when playing notes from these converted files are also 
much greater than with the supplied samples or imported AKAI samples 
direct into the EXS.

HELP.  Am i missing a setting or something?  I'm a newbie to al of 
this sample library conversion stuff.  I didn't
think the conversion would be so poor.  The Roland
De-emphasis menu item was checked when i made the
conversion.  The sustain and decay times are different too.  The 
original S760 sample decays out while holding the keys down.  the EXS 
version just continuously loops without decaying.  I thought the 
translator was supposed to translate all parameters?
Any help would be great...
thanks all.
