Does it have to be possible to pirate? EWQL have the best orchestra libraries I've heard. First place: Hollywood Orchestra (four installments for brass, strings, woodwinds and percussion. Second place: Symphonic Orchestra (gold or platinum), affordable and realistic. Buy the mic position extension too (close and surround in addition to stage) and learn how to make them sound as realistic as possible.
If you can make do with generic strings sections (max hollywood feel) you can use the non-ilok ones like Session Strings for Kontakt. It has a neat spic/stac pattern programmer and works fine for string sections, but it just doesn't feel as high quality realistic as the more classy sounding libraries that require a dongle with authentic licenses connected to your PC to use.
I'll see if I have an example on SC.
