This paper describes a new Beagle Board-based platform forteaching and practicing interaction design for musical applications. The migration from desktop and laptop computerbased sound synthesis to a compact and integrated control, computation and sound generation platform has enormous potential to widen the range of computer music instruments and installations that can be designed, and improvesthe portability, autonomy, extensibility and longevity of designed systems. We describe the technical features of theSatellite CCRMA platform and contrast it with personalcomputer-based systems used in the past as well as emergingsmart phone-based platforms. The advantages and tradeoffs of the new platform are considered, and some projectwork is described.
