Emu XL-7 & MP-7 User's Group

i finally have time to play with my new XL7.  i'm trying to 
understand the master effects.  i.e. i have a cool delay going with a 
beautiful synth on track 9, and i'm ready to do a basic drum loop, 
but i can't figure out how to keep it from delaying.  on my yamaha 
rm1x there's a variation control on each channel for the FX.  how do 
i do this on the XL7?
