Affiliated Researchers:

Jay Cloidt; sound design and diffusion

Mark Goldstein; musical software engineering

David Wessel Director of CNMAT; Professor of Music; Affiliate of the Department of Psychology Interests include interactive composition and performance, analysis and synthesis of sound, music perception and cognition.

David Wessel studied mathematics and experimental psychology at the University of Illinois and received a doctorate in mathematical psychology from Stanford in 1972. His work on the perception and compositional control of timbre in the early 70's at Michigan State University led to a musical research position at IRCAM in Paris in 1976. In 1979 he began reshaping the Pedagogy Department to link the scientific and musical sectors of IRCAM. In 1985 he established a new IRCAM department devoted to the development of interactive musical software for personal computers. In 1988 he began his current position as Professor of Music at the University of California, Berkeley where he is Research Director of CNMAT. He is particularly interested in live-performance computer music where improvisation plays an essential role. He has collaborated in performance with a variety of improvising composers including Roscoe Mitchell, Steve Coleman, Ushio Torikai, Thomas Buckner, and Jin Hi Kim, and has performed throughout the US and Europe.

Adrian Freed CNMAT Software and Systems Development Director Interests include reactive real-time systems design and implementation, spectral and physical models for sound synthesis, user interfaces, musical hypermedia.

Guy Garnett CNMAT Music & Technology Director; Director of the CNMAT Ensemble

Interests include score following, performance gesture tracking, compositional tools.

Guy is a composer, conductor, researcher, and theorist. He specializes in using new technologies to extend composition and performance resources, especially in the area of live electronic performance. He is currently Music and Technology Coordinator at CNMAT. He is a cofounder, with David Wessel, and director of the CNMAT Ensemble, an Ensemble dedicated to the presentation of works involving both performers and live electronics. He recently performed new works in Korea with the CNMAT Ensemble and his Concerto for violin, orchestra, and conducted electronics was performed by the University Orchestra at UC Berkeley, with Mari Kimura in the solo role.

RESEARCH

Since 1986 I have been involved in several computer music research projects. These are sketched below. I have experience with computer music systems as a user, programmer, and designer as well as in system management. This includes Unix-based workstations (SGI, NeXT/ISPW, Sun), Lisp machines (Symbolics), and Macintosh and MIDI systems, software such as cmusic, cmix, csound, SoundDesigner, Finale, Max, MacMix, and others. I am an expert on Max.

REAL-TIME HANDWRITTEN MUSIC SYSTEM

This project is in the early stages of design. The goal is to be able to use real-time handwriting, on a touchscreen for example, as a basis for entering music scores. We have tested some prototype networks, based on work in cursive script recognition, and successfully recognized simple music characters. We have also defined a large part of the software architecture to handle the complex internal representation of the score and editors.

CONDUCTING PROJECT

Since 1992, I have been developing software for computer following of conducting gestures. The system as currently developed uses a Buchla Lightning and a Macintosh computer and will follow the tempo, dynamics and phrasing of an orchestral conductor (as used in my recent Concerto for violin, orchestra and conducted electronics). The software is written in Max.

CNMAT RESEARCH PROJECTS

I have been involved in a number of research projects at CNMAT since its beginning. These have included work on highlevel control software for the RESON8, neural network control of DSP, and, currently, developing new control paradigms for realtime synthesis on SGI computers.

SMALLTALK COMPOSITION PROJECT

From 1987 through 1990 I developed Smalltalk systems for use by composers. I wrote a suite of Smalltalk MIDI primitives that was distributed widely. I developed software tools to assist my compositional interest in exploiting various non-pulse-based temporal systems.

YAMAHA MUSIC TECHNOLOGIES

In 1988 I was hired by Yamaha Music Technologies as a Chief Engineer. My main work there was exploratory research, system design, and representation issues.

MUSIC RECOGNITION

At Stanford University's CCRMA, I was hired as a Research Associate in the Music Representation Project working under Bernard Mont-Reynaud and funded through the NSF. I developed Smalltalk software for display of signal representations.

WAVEGUIDE SYNTHESIS

While at CCRMA, I organized and funded (through the German audio company Dynacord) a project to research the use of waveguide filters to simulate the acoustics of the grand piano.

Cal Arts, Flute Fantasy (Rachel Rudich);

I perform regularly as a conductor, keyboardist, and electronic specialist. In the latter capacity I have worked with the San Francisco Symphony and with Alternate Currents new music ensemble.

PRINCIPAL MUSICAL/THEORETIC INTERESTS:

Rhythmic theory and practice, meter and phrase grouping phenomena (e.g., Lerdahl and Jackendoff), and non-pulse-based systems (as used in my computer-performed composition Four Trios).

New models of music theory based on phenomenological approaches to understanding musical perception and organization (Clifton, Lewin).

Synthetic performance using computers and/or synthesizers. Recent performances have used my computer conductor-follower techniques and interactive electronics.

My interests include adaptive methods and learning algorithms based on neural networks, fuzzy systems, and genetic algorithms with application to intelligent and adaptive user interfaces, learning control, knowledge acquisition and extraction, embedded systems, interactive music systems, and reflective programming systems. Particular goals are to develop techniques for building expressive user interfaces, explore techniques for auditory display, and to develop highly interactive data exploration environments.
