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

I asked this question already but no one replied, so keen to ask
again. I was thinking about getting Beat Garden and Techno Yard roms
for the command station. Do people find these worthwhile? Also what
other roms have been tried that users find useful.
cheers

PS also no one replied about quick editing the parameters like an XL
synth...any ideas??
