Kurt James Werner is a Ph.D. candidate in Computer-Based Music Theory and Acoustics (CBMTA) @ Stanford University's Center for Computer Research in Music and Acoustics (CCRMA, pronounced “karma”) and is active as a researcher and writer, composer of electro-acoustic/acousmatic (&c.) music, author of digital signal processing code & compositional algorithms (see: Grani+, boots&cats&&&, &c.), & circuit-bender. His research focuses on theoretical aspects of wave digital filters, computer modeling of circuit-bent instruments, & the history of music technology.
His Ph.D. dissertation (anticipated: 2016), tentatively titled “Like an 808: Circuit Models and Analog Musicology of the TR-808, including Advances in Wave Digital Filter Theory,” is aimed at recovering a holistic history of a very important analog drum machine, the Roland TR-808. By drawing out conceptual antecedents to its voice circuitry, situating it as an important element of hacking and circuit bending traditions, & advancing the technical state of the art of circuit modeling techniques, this work both comments on and contributes technical tools to a long chain of percussive mimicry.
His music references elements of generative composition, breakbeat, chiptunes, musique concrète, circuit bending, & (granular & otherwise) synthesis, in juxtaposition & superimposition, directly & indirectly. He holds a Bachelor of Science in General Engineering (w/ a secondary field in Acoustics) & a Bachelor of Music in Composition/Theory from UIUC (the University of Illinois at Urbana-Champaign).
