Short Bio: David Ogborn (aka dktr0) is an artist programmer and interdisciplinary researcher, based at the southwest corner of Lake Ontario, and devoted to the pursuit of improvisation and play in computational settings. Specific passions include making new programming languages, collaborative platforms, electronic music, sound and media art, and video games, often but not always with others. He is an Associate Professor in McMaster University’s Department of Communication Studies and Media Arts, where he coordinates the Networked Imagination Laboratory (NIL), and teaches in the undergraduate Media Arts program, the MA in Communication and New Media, and the PhD in Communication, New Media, and Cultural Studies.

Projects

LocoMotion (live coding language for dance, choreography, 3D avatars):

Created in collaboration with Kate Sicchio and a team of research assistants (full credits at github repository) at Virginia Commonwealth University and McMaster University

Punctual (audiovisual live coding language):

Punctual is a live coding language that aims to use similar abstractions for both visual results (fragment shaders) and audible results (audio synthesis), while also providing emphatic notations for transitions between new and old programs.

estuary (zero-installation, browser-based collaborative live coding platform):

Created as the primary outcome of two SSHRC grants, and the focus of ongoing development, Estuary is a zero-installation, web-based collaborative platform for audiovisual live coding, with a dual emphasis on supporting multiple live coding programming languages (in increasingly modular ways) and on enabling networked ensembles (whether across the same room, or around the world).

Cybernetic Orchestra (open laptop orchestra):

The Cybernetic Orchestra is the open, improvising, live coding laptop orchestra at McMaster University, formed in early 2010 and still active in 2023! New members of any level of experience are invited to join at pretty much any time, on an ongoing basis. The group has released five albums, collaborated with musicians from around the area and around the world, and performed at all kinds of festivals and conferences.

MEDIAART 3L03: Game Design

I proposed the course MEDIAART 3L03 as a new course in the Media Arts program, for 2014, and have taught it 4 times since then. In the second half of the semester, the class forms into a single team to work on a collective game together.

very long cat (tabla and live coding duo):

Shawn Mativetsky (tabla) and I formed this duo in early 2015, to explore network music possibilities (improvising together while staying in Montréal and Hamilton respectively) and the possibilities of combining live coding with specific instrumental performance traditions. The name comes from a quote, misattributed to Einstein, once included in the UNIX 'fortune' program, and suggested to us somehow (I forget how) by Alex McLean, regarding the nature of the radio: "You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat."

daem0n (guitar/live coding performance piece with autonomous agent):

In the piece Daem0n, I play guitar along with an autonomous agent that live codes the rest of the music, and sometimes I tweak the code it generates as well. I first created Daem0n in mid 2014, ahead of a series of performances in a mini "algorave" tour in the UK, and then continued to sporadically come back to the piece thereafter, making big changes to how it works and sounds (in the first version everything happened within SuperCollider, while in the last performed version SuperCollider was used for machine listening, TidalCycles was used for live coding, and code generation and display was done with JavaScript in the browser). Inspired by the example of George E. Lewis and Voyager, I plan to cultivate the piece over the long term as an improvising partner in a relatively specific musical context/idiom.
