This piece for magnetic tape is - from several points of view - a confrontation of various worlds. First of all, on the music-technical level: the production process. The means of the classic studio, the manual aspect of the work on one side, the generation of basic sound materials on the other side. In addition, the piece is a confrontation of concrete sounds and electronic sounds.The complex spectrum of the human voice is used in this case as a "plastic algorithm" of great flexibility and considerable variability. A hybrid, quantitative analysis results in information that is used by the program to make decisions for controlling a program outside the computer. The program conceived and developed by the author (Oscar, acronym for Oscillator Artist) allows a complete navigation between one-to-one relations and a completely automatic algorithmic synthesis, in the human dialogue-to-machine. This piece was designed for tape but performed with live performance procedures. The piece uses some FM sounds recorded at the Studio of the University of Toronto in 1979. The piece was made in the private studio of the author. The final mix was performed at the IPEM studio, Ghent, in November / December 1984.
