Mattias Westlund has introduced the Sonatina Symphonic Orchestra, a Creative Commons licensed orchestral sample library that's free as in beer - and as in speech.
Here's what Westlund has to say about the free sample library:
Sonatina Symphonic Orchestra is a free orchestral sample library. While not as advanced or ambitious in scope as commercial offerings, SSO contains all the basic building blocks for creating real virtual orchestrations. It’s primarily aimed at beginners, but also more experienced composers looking for something lightweight and/or portable might find it useful.
SSO comes in sfz format, which is a powerful, open, non-monolithic sample format. It consists of a plain text file with an sfz extension that holds all sample playback parameters, and a set of sound samples in wave format which are referenced by the sfz file. This means that sfz files can be edited with any plain text editor, and the samples can be edited with any audio editor that loads wave files.
