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

Sorry if this has been brought up before...Is there some software out 
there (or could EMU create some) that would allow you to load samples 
into the XL-7/MP-7 ROM from a computer, instead of the E4 sampler way?

Something similar to the Roland SP-808 WAV Converter program, which 
allows you to load WAV files from a PC/MAC onto a ZIP disk that can 
then be used in the SP-808.  (FREEWARE provided by Roland, by the 
way!)  Maybe the Command Station could get the samples via the USB 
port or some other way...?  

I'm thinking of getting an XL-7/MP-7, but don't really want to get an 
E4 sampler, just to have samples in my groovebox.

THANKS!
