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

I have an XL-7 which has served me well for quite a few tunes I have 
put together, but I am seeking a rom with a larger selection of 
synth basses and synth pads in particular. Alot of the extreme lead 
basses sound so similar/quacky/techno-ish no matter how I tweak them 
(which thats what it was meant for of course) but I really need some 
more vintage synth basses (think depeche mode's "Construction time 
again" and "black celebration" albums, those fat bouncy synth 
basses). I heard the "proteus pop collection" may have what I am 
seeking, but I wanted to see what you guys thought and if you can 
help me out at all before I buy something I will regret. Thanks alot.
