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

I got my Virtuoso 2000 in today that I bought used. It came with OS 
1.21 and I was thinking about upgrading the OS from the Emu web 
site. The only OS available is 2.26. I am trying to remember if this 
is the OS that adds beat mode, and takes away part of the user patch 
memory. I don't really need beat mode. That is why I have the XL-7. 
I do want to keep my 512 user patch locations. Does anyone know if 
this is the OS I want to stay away from. Is there any real need for 
me to upgrad from OS 1.21? I plan to move my Beat Garden ROM into 
this unit, and later add the Protazoa. I am not sure if either will 
require an OS upgrade.

Thanks,
Robert
