The Music Kit was a software package for the NeXT Computer system. First developed by David A. Jaffe and Julius O. Smith, it supported the Motorola 56001 DSP that was included on the NeXT Computer's motherboard. It was also the first architecture to unify the Music-N and MIDI paradigms. Thus it combined the generality of the former with the interactivity and performance capabilities of the latter. The Music Kit was integrated with the Sound Kit.
