The OLPC has donated 8.5+ gigs of samples to the children of the world, and us. This library is licensed under the Creative Commons Attribution License. So feel free to start remixing.
From the official press release:
Several prestigious groups of musicians have donated their sound libraries to One Laptop per Child (OLPC), a non-profit organization focused on providing educational tools to help children in developing countries “learn learning.” The XO laptop’s unique user interface and applications enable children to create and share music, drawings, video, personal diaries and other things they make online with family and friends worldwide.
Leading musicians, colleges and companies making their sound libraries freely available on the XO laptop are: The Berklee College of Music in Boston, Berklee Music Synthesis alumni – including electronic music superstar BT, the international Csound Developer community, M-Audio and Digidesign (parts of Avid Technology, Inc.), and the Open Path Music group.
I want thank Dr. Richard Boulanger for all the time and effort he put into collecting and assembling such a vast and wonderful resource.
Here are my donated samples in three different sampling rates: baby talk plus eurorack, serge and csound synth sounds
