The massive multimedia performances Xenakis called polytopes Mycenae-Alpha is also the first work to be composed entirely on the UPIC system. The UPIC is a tool for the graphic composition of electroacoustic music which was first developed in the late 1970s by Xenakis and his staff at the Center for Studies in Mathematical and Automated Music in Paris.
