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

My local music shop is selling off EMU modules for dirt cheap.  They 
are selling the Proteus for 600. XL1-B3-ORBIT for 399. and the 
planet earth for 250!

Man the same store is selling the roms for 400.

so my question is this can i pull the planet earth rom out of the 
module and throw it into my XL?  From what I have read here I get 
the feeling that i could do this but only the first four controllers 
on the xl will affect the sounds of that rom.  is this correct?  In 
this case i would just have to manualy set up the controllers?

OH YA get this, i had some major problems with my first XL so I 
returned it to the same store.  I have good status at that store so 
they upon my request just gave me a new XL.  At that time i had no 
way of backing up my patterns so they went off to Cali with the box 
never to be seen again as far as I was concerned, a sad day.  Any 
way I was looking at the MC909 to see what what I thought of it.  
After working with it for a wile I went over to the XL-7 they had 
sitting there and hit play to see the sound difference and go figure 
I was listing to MY music!  What a freaking trip!  I then took a 
closer look and reolized that it was my old XL-7!  So my question 
here is what is the best way for me to re-record the patterns into 
my new XL7?  man what a weird day it has been. 

 P.S.  the roland sounded thin over all compaired to the XL.  Hard 
to put my finger on what excatly the difference was but the EMU just 
had a much warmer and fuller sound.  

Ok think that is it, Man it kinda makes me worry when i see all the 
EMU gear droping in price so drasticly.  It makes me wonder if EMU 
is in some serious troble.  I hope not.

Any info would be great and I think time is of the essence here due 
to the price of the gear.

Thanks
