I’d love to get some of the top-shelf orchestral libraries, but I don’t really have $2,000 lying around. And I love Free Things!
So I’m going to suggest taking a look at Sonatina Symphonic Orchestra. It’s free as in free speech and free beer. The quality is good, not great, but that’s all I need at my level.
The SSO library uses the SFZ open format, and the only player I can find anymore is the free SFZ sample player at Plogue. I tried to find the Cakewalk SFZ player, but all I got were 404 errors.
Plogue also kindly assembled a bunch of free samples for the SFZ player from Garritan, Digital Sound Factory, Analog Industries, Patch Arena, and Plogue as well! And they’re free!
