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

Is there a resource anywhere that lists all instruments of all ROMs?
BTW that what Emu calls "instrument", the rest of the world calls
"samples" or "wave data", right?

I found several duplicates between the XL7 standard ROM ("Xtreme
Lead") and the "Proteus Pop" expansion that I bought it with. Not
complaining - I practically paid nothing for the expansion, but I want
to make sure that when I buy a new ROM, it doesn't contain too many
duplicates.

Looking to expand with "Techno Synth" and "Beat Garden", and later
perhaps replace the "Proteus Pop" with the "Vintage" ROM. Could use
some ethnic percussion also. Does "Beat Garden" offer enough of that?
I'm thinking of clay pots, water drums, and talking drum samples.

But for the moment, instrument listings is what I'm looking for.
