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

I was playing with a mp-7 last weekend and noticed that 'beats' 
weren't one of the categories of preset.  I assume 'beats' are 
somehow subsumed into the 16 track patterns on the box.  I would 
expect that there should be a 1-1 mapping (more or less) of 
the 'patterns' on the mp-7 to the beats on the mo'phatt.  Is this 
true?  I've looked at the listing of beats on the mo'phatt, the pure 
phatt rom, and the patterns on the mp-7 and they seem to have more or 
less the same names.

So, what happens to the beats from the different roms I would add to 
a mp-7?  Do they just become more patterns on the mp-7?  I was hoping 
to be able to mix tracks from the Beat Garden and World Expedition 
roms' beats with tracks from the native mp-7 patterns.  Anyway to do 
this, short of syncing an Orbit3 and Planet Earth with a mp-7?  
Thanks for any responses.
