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

Hello,
Sorry to keep bothering you guys. Here goes....when you edit sounds 
on the E-MU modules (ie: apply effects, adjust filters, etc.) is 
there on-board memory to save them as user-edited sounds? I know 
there's 512 presets (or at least I think that's what I read), so how 
many user-presets are there, if any?
