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

Roms which would you suggest.
Firstly I do not mind obviously digital sounding textures.
Secondly I love to program my own sounds.
I like stuff like autechre ,mouse on mars ,orbital ,blackdog ,visions 
of shiva and a lot of obscure electronica .
My thought's where PX rom -extra drums ,Vinatge Rom -lots of raw 
waveforms from the classics to mangle at will. And either the Beat 
Garden ,Techno , or XL-7 boards .
Which do you feel would best suit that style sonically ???
Any replies greatly appreciated.
Oh yes and lastly if I have synths connected to the sub outs as 
inputs do they output through the SP/DIF digital out also ?
Thanx
