Pure Shift Productions has released the Music Box sample library. This is a library created with a programable music box that has a two octave range in the key of C and is mapped from C1 to C3 chromatically. C4 a rewinding sound effect and D4 is what the music box being cranked with nothing in it. The latter is designed to be effective in the background to make a composition sound more authentic. Each note has three round robins and there are files to load it into either Native Instruments Kontakt (full version) or NN-XT in Propellerhead Reason.
