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

I'm a fan or Rob Papen's Albino VSTI softsynth and I'm curious about his sound designing for EMU. I read about the Orbit 3 and thought about possibly getting it, but it really has more to do with the rom than the unit doesn't it? Did he author the Techno Construction Yard rom?

I just acquired an XL-7 and love it. I'd rather just get roms to expand it rather than buy the Orbit 3.

Also, I am mainly interested in performing/producing Drum n' Bass electronica. What would the fine people on this group suggest? I've heard the MoPhatt rom is preferred by junglists.

Thanks in advance!
