If I had an XL-7 and really good orchrestra sounds for creating 
symphony type songs, which would be the best ? From the Emu.com site, 
I know there are the following:

Sound ROMs

The Orchestral Sessions Vol. 2 expansion 32MB ROM offers you the most 
realistic and comprehensive collection of woodwinds, brass, 
percussion, and solo strings available - the same sounds featured in 
E-MU's Virtuoso™ 2000 sound module, complete with velocity switching

Now the 3 that I'm currently interested in are:

Peter Siedlaczek Advanced Orchestra 
Orchestral Sessions Vol. 1 32MB 
Orchestral Sessions Vol. 2 32MB 

However I don't know which one is the best, or has the best sounding 
sounds. Any help ?
