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

Does anyone have an *.ins* file for the xl-7 so i could import the 
presets to cakewalk?  i really don't understand cakewalk's 
instructions on how to create your own instrument list...  If someone 
has that file please let me know, or if you know how to create the 
instrument within cakewalk I would be interested in learning how to 
do that as well...  Thanks!!  (oh, and if anyone has a file for the 
mc-505 i am looking for that too!)
