Sounds Online is offering a free symphonic orchestra sample library to anyone that fills out their online survey
Here's what they have to say about the offer:

It works with most sequencer/notation hosts including Ableton Live, Cubase/Nuendo, Digital Performer, Finale, FL Studio, Garageband, Logic, Pro Tools, Sibelius, Sonar, etc. Or you can use it as a standalone application with your music keyboard.
When you download the free version, Sounds Online will email you a code for a discounted upgrade to full versions. The free version, though, is not handicapped and is not time-limited.
