Hi Pete -

In EXS you could assign a closed hihat sample and a separate 
half-closed hihat sample to different Groups on the same note, and 
set the Groups to crossfade in response to different ranges of CC4, 
so opening the pedal fades between the closed hat to the half-closed 
hat sound. You can also use this technique to make the 
closed-hihat/pedal-hihat cut off any open hihat sounds - you could 
have two or three hihats (Closed/Half/Open)on the same note 
(apparently G#1 in the DTX) all crossfading in response to different 
ranges of the CC. *However* in Logic 7.1 they have some odd CC 
re-mapping in effect automatically when CC4 is used for this purpose, 
so you should re-map CC4 to some other controller # on the way in and 
use that in the EXS patch..

>  Note C#5          OFF

Yes, I'm not clear on the exact timing of the Note-Ons and Note-Offs 
from the list above, but it does look like the Note-Off messages 
could be on an internally-timed release - perhaps there's a setting 
for that in the DTX? Is the Splash sound (C#5?) triggered at higher 
pedal velocities and the regular Foot-Closing sound (G#1?) triggered 
at lower pedal velocities?

Let me know if you decide to try the EXS Group-crossfade setup, I 
could describe it in a little more detail if I have Logic open..

Btw, there have been a number of threads on this topic (hihats in 
EXS) - you might want to search the archive, there should be quite a 
few posts..
