THE MAX PATCH

A MAX software "patch", developed for this performance, examined the brain wave (MIDI) activity. Events were left unchanged, filtered, distorted, transformed, or modulated by other events or tendencies, responded to, etc. By choosing what to play and how, the patch circumscribed the audio aesthetic.

The patch was "played" with a continuous MIDI controller and through initial neural activity and by responses to aural articulations. Variable in this collaboration were the activities of the two individuals as well as the patch; these engender unpredictable results.

Projected animation sequences were used to represent states of mental activity. These sequences were triggered by brain wave switching among corresponding frequency domains (high beta, low beta, alpha, theta, and delta) by using abrain wave interface to the computer.

THE PERFORMANCE

"That Brain Wave Chick" is a collaborative music composition produced by Mark Applebaum and Paras Kaul.

The brain wave interface used for performances of "That Brainwave Chick"is IBVA (Interactive Brainwave Visual Analyzer System).

At the Walker, this interface was on Paras's computer. The composition was produced by neural activity which was transformed from her computer into real time MIDI data which was then transferred to Mark's computer where the the data was modified by the Match Patch before being articulated by synthesizers.

The brain wave interface utilizes standard EEG monitoring of neural activity. Amplitudes of the signal were converted to MIDI velocities, and frequencies were converted to MIDI note numbers.

Mark Applebaum
Paras Kaul

Mark Applebaum received his Ph.D. in music composition from the University of California, San Diego where he studied principally with Brian Ferneyhough. His solo, chamber, orchestral, choral, and electronic music has been performed throughout the United States, Europe, and Japan with notable premieres at the Darmstadt New Music courses. He has received commissions from Betty Freeman, the Jerome Foundation, the American Composers Forum, the Paul Dresher Ensemble, and the Merce Cunningham Dance Company, among others. "Mousetrap Music" a CD of his sound-sculptures was released on the Innova label. He has served as the Dayton-Hudson Visiting Artist at Carleton College; in 2000 he joined the faculty at Stanford University where he teaches composition and theory.

Influenced by early experiences with hypnosis, Paras Kaul began research using a brain wave interface to the computer in 1992. This research evolved from an interest in human dolphin communication She received an MFA degree in computer animation and video from the School of the Art Institute of Chicago and earlier completed graduate studies in photography in Northern California. Her work with Neural Audio Imaging has been presented by ACM/SIGGRAPH in exhibitions in Florida and Los Angeles, and she has been invited to speak at conferences in Australia and France. Currently she is a Coordinator for the university web site at George Mason University. (www.gmu.edu)
