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

Hi.
The other day I was complaining big time about the MP7, right?
Well, I kinda like it more now that I installed OS 1.18 and got rid 
of the horrific Phatt Rom and replaced with the Composer Rom 
from a P-2000.
Now my question is, can I download the original sequences 
from the P-2500 from somewhere, so that I get some patterns 
back into this machine? The MP-7 one won't really do I guess...
And also, I have another question. P-2500 is marketed as having 
a faster processor and a higher bit output. Can we owners of 
lesser models upgrade to that technology sometime in the future 
or never? And is it going to make a real difference?
Thanks for answering.
