Peter Elsea’s work focuses on the connection between musicians and the new technology of music. This technology has created profound changes in the tools used by composers and performers, and the music of the next century will largely be shaped by the techniques now being developed to use these tools. Elsea is involved in this development at all levels: as composer, teacher, circuit designer, programmer, and troubleshooter. The fruits of his efforts are the UCSC electronic music studios, five rooms containing the best of recent equipment integrated into efficient composition systems. Elsea is also developing instruments and programs that will expand the possibilities of midi beyond the traditional and commercial forms of music associated with the format.
