Timbre, gesture, Open Sound Control, additive synthesis, parallel computing: These were just a few of David Wessel’s many brainchildren. As a Professor of Music, a founding director of Center for New Music and Audio Technologies (CNMAT), and an Affiliate Professor of Psychology at UC Berkeley, David Wessel was a wise advisor and a wonderful scientist, musician, and friend. I will narrate the exceptional experience of working with the creative force that was David Wessel, both from the perspective of a music perception and cognition scientist, and through the lens of Berkeley's CNMAT, which thrived under his leadership as a synergistic center for performers, researchers, and composers.
