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

Since user preset banks can be loaded via MIDI.(ex xl-1 preset banks, 
TSCY extentions  etc)..does any one have any information on this 
(that they are able to divuldge)??  I'd like to archive a few of my 
patches/banks and wack the rest...From what I gather eloader is for 
patterns and songs only NOT presets...
