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

So Id really like to back up ALL the stuff on my Mp-7. However, 
as if understand correctly, eloader only saves sequences?? So I read 
something awhile ago about doing a sysex dump and storing the patches 
via MIDI. Is there anyway I can get a HOW-TO on this subject?? Id 
really like to back up all of my patches and multis also. 

Thanks for your time.
