Yeah, does seem lame. I just checked out Spectrasonics and they're stuff is clear for use creating music libraries which is wicked news. Plus, they even make mention that this is kind of unusual and that most companies don't permit this.
Perhaps this would be a good thread for people to list companies that don't set this limitation?
I'll look into the Sony ones. Thanks for the tip!
I was PM'ed that
www.soundsonline.com licensing covers library production too (with some requirements)
Here is another company that offers 'special licenses' upon request:
ZERO-G
7. Use of the sound samples in 'library music' (also known as 'music libraries'), which is relicensed to multiple third parties, is not permitted without first obtaining a separate License (subject to availability) from Licensor.
