Ok, is it possible to control the Send amounts in real time?  Preferably a 
way to assign the "Wild Knobs" to control effects depths?  I looked in the 
Midi Implementation chart, but didn't see any info there.  Also on page 
280 of the manual it mentions that the Sys Ex Spec is available online at 
Emu's site, but I can't find it (it's not in the download's area).  Anyone 
got a copy or know where I can get one?  Yes, I'm a masochist and actually 
want the Sys Ex Spec...

Thanx
