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

Hello,

I am a new member here, although I have browsed before. I am looking 
to buy a PX-7 (it's just too sexy, and I want the Emu sound).

ROMs seem to be going fast. I am trying to choose two (I'd like to 
leave one slot open for now) from the following:

proteus 2000
pure phatt
beat garden
xl-7 rom
sounds of ZR
peter Z orchestra

I have other synths so I do not need many electronic sounds, 
although if the xl-7 rom is super-cool I may want to go for it.  Can 
you guys help with some suggestions? I know I want the vintage 
collection rom and will keep an eye out for that on ebay. Pure phatt 
also sounded great from the samples I heard on the Emu site.
