Sever Tipei immigrated to the United States from Romania in 1972. He studied composition and piano at the Bucharest Conservatory and at the University of Michigan. He has taught at the University of Illinois since 1978 and currently manages the Computer Music Project of the University of Illinois Experimental Music Studios.

An enthusiastic proponent of computer-assisted composition, Mr. Tipei has been actively involved in the creation of programs to such ends since 1975. In MP1, the first of such programs, sonic events are treated as vectors in a multidimensional space. It operates through the use of stochastic distributions, sieves, and Markov chains. The process involved is modeled after that of a scientific experiment, where initial conditions are set, a process set in motion (and left to run its course), and results received which are used unaltered as the final composition.

DIASS (Digital Instrument for Additive Sound Synthesis) is a virtual instrument developed from the Music4C sound synthesis program. DIASS can be used to create complex sounds with numerous partials, each able to be controlled independently of the others. One additional feature of DIASS is that it scales the amplitudes of sounds based upon the relative complexity of their harmonic content in order to have dynamics work in a perceived manner rather than as absolutes. MANIFOLD is a program for computer-assisted composition employing sieves with static and dynamic random distributions.
