MCABC 0475 is the first composition generated by MCABC (Music Composition Aided by Computer), a computer program written in PL/1. Its duration is approximately 14 minutes. Using a North Texas State University computer library program, the full score and parts were drawn by the CALCOMP plotter. The text, which discusses processes and procedures in developing MCABC 0475, as well as indeterminacy, aesthetics of computer composition, and pro gr am user information, was printed by the IBM 1403 line printer using an ALA chain which has both upper and lower case characters.

Performances of multimedia works are hampered by the difficulty of controlling large numbers of incandescent lamps rapidly and accurately. The instrument described in this document is aimed at alleviating this problem. Chapter I describes the design and operation of the voltage-controlled dimmer unit and the DC controller. Chapter II describes step-by-step procedures for building the instrument. Schematics, wiring diagrams, and illustrative photographs are included. Chapter III discusses some of the aesthetics and philosophy of multimedia composition, and then describes various scenarios which utilize the instrument. Included are the connection of peripheral control equipment, audio/Video interfacing, and the potential for constructing prepared tapes which will automatically drive the dimmers. The prototype was built at the NTSU Electronic Music Center.

Grimaldi is a synesthetic work composed of aural and visual media including noise, tone, electronic devices, lighting and theatrical events. It is designed for solo saxophone with an accompanying ensemble of eight wind instruments and four percussion. The most important aspect of the piece is its texture, which consists of constantly changing and interacting aural and visual events. The compositional process of Grimaldi began with the selection of a form constructed of two equal arches of unequal subdivision, and the designation of texture for each section. After these selections were made, the theatrical elements were selected, based on a traditional story about the clown Joseph Grimaldi (1787-1836). By gradually refining these general selections into specific notation, and by considering them as a whole rather than individually, consistent relationships were maintained.
