Fernando Lopez-Lezcano (Argentina-USA) is a composer, performer, lecturer and computer systems administrator at CCRMA, Stanford University. He has been teaching and taking care of computing resources there since 1993, and created and maintains since 2001 the Planet CCRMA collection of open source sound and music packages for Linux. He has been involved in the field of electronic music since 1976 as a composer, instrument builder and performer, blurring the lines of his dual background in music (piano and composition) and electronic engineering. His music has been released on CD and played in the Americas, Europe and East Asia. He taught at Keio University in Japan in 1992 and recently was the "Edgar Varese Guest Professor" at TU Berlin during the Summer 2008 semester.
A Very Fractal Cat, Somewhat T[h]rilled (2008-2010)
This is the latest of a series of performance pieces for pianos, computer and “cat” (the proverbial cat walking on a piano keyboard). The performer connects through a keyboard, four pedals and two wheels to virtual pianos, directly and through algorithms. Markov chains, fractal melodies, scales and trills are used throughout the piece. The pianos are heard directly, processed using spectral and granular techniques and spatialized using Ambisonics. The software was written in SuperCollider.
CatMaster and “A Very Fractal Cat”, a piece and its software
This talk describes the genesis and evolution of a series of live piecesfor a classically trained pianist, keyboard controller and computer thatinclude sound generation and processing, event processing andalgorithmic control of the structure of the piece. The pieces are basedon piano sounds, and include granular and spectral processing andadditive synthesis. The control and processing software is written inSuperCollider and the program (CatMaster) is currently around 5300 linesof code.
