EXS 24 Logic Sampler Users Group

Hi,
I just received my Flossmode Studios sample discs of the Triton, 
MOTIF ES, and the Fantom X! These sounds are amazing! I've tried 
them with the EXS24 in Logic Pro 7 but it seems I have to adjust 
the release on some of them. However, when I converted them for 
Machfive the release times were better and actually easier for me 
to edit since I'm more familiar with it. However, can anyone help 
with info on shortning release times with the EXS24?
