File under "Wha???"


In an apparent attempt to appeal to the "You-Tube" generation, Stanford commissioned a series of "promotional" clips to be shown during football game televised broadcasts focusing on the technological achievements made by Stanford persons... unfortunately, CCRMA founder John Chowning's discovery of FM synthesis was one of the achievements selected.

Bad Stanford, Bad.

ECHO::Canyon

ECHO::Canyon was premiered at CCRMA's 2013 Music and Games concert, on April 25, 2013 in the CCRMA Stage. ECHO::Canyon is the first UDKOSC work to make use of UDKOSC's OSC player and pawn scripting features.

All audio for this work is synthesized procedurally in real-time from data pulled from each virtual actor's gesture and motion through the virtual environment. Data sources for each synthesized instrument/voice range from coordinate position in 3D space to individual bone-locations and rotations on the avatar itself. In this manner, macro gestures (of the actor in relation to the environment) as well as micro gestures (comprised of gestures made through animation and motion by the actor's body parts) can be used to control sound and music.

The fantastic artistic design, sculpting, modelling and animation are all the work of Chris Platz.

- http://www.leonardo.info/isast/journal/toclmj21.html

Abstract:

This article explores the role of symbolic score data in the authors’ mobile music-making applications, as well as the social sharing and community-based content creation workflows currently in use on their on-line musical network. Web-based notation systems are discussed alongside in-app visual scoring methodologies for the display of pitch, timing and duration data for instrumental and vocal performance. User-generated content and community-driven ecosystems are considered alongside the role of cloud-based services for audio rendering and streaming of performance data.

Multi-modal musical environments for mixed-reality performance

Multi-modal musical environments for mixed-reality performance, written with Juan-Pablo Caceres, Chryssie Nanou and Chris Platz, is now available in the latest Journal on Multimodal User Interfaces (Springer).

- http://www.springerlink.com/openurl.asp?genre=article&id=doi:10.1007/s12193-011-0069-1

Abstract:

This article describes a series of multi-modal networked musical performance environments designed and implemented for concert presentation at the Torino-Milano (MiTo) Festival (Settembre musica, 2009, http://www.mitosettembremusica.it/en/home.html) between 2009 and 2010. Musical works, controlled by motion and gestures generated by in-engine performer avatars will be discussed with specific consideration given to the multi-modal presentation of mixed-reality works, combining both software-based and real-world traditional musical instruments.

In C Variations for MadPad (iPhone and iPad)

To explore the concepts of crowd/cloud-sourcing musical performance content and inspiration I started the In C Variations project using Nick Kruge's MadPad app for iPhone and iPad. Users can generate their own sets of cells, and share them in the MadPad app.

The first sets we used for the Sept. 13 UNO Mobile Phone performance can be downloaded here:

q3osc: fully-featured osc output for ioquake3

A heavily-modded ioquake3-based performance environment with a full Open Sound Control implementation (oscpack) compiled within. q3osc tracks not only individual game-client xyz data but also tracks individual projectiles as they move through the environment. Modded features like homing projectiles and bouncing projectiles allow for more compositional choices in using the environment.

iPaq with Java-based OSC client

Using the Mysaifu JVM on an HP iPaq rx1950, with a hacked-up version of the illposed.com JavaOSC classes and demo app, I put together this little mixer interface to play with. It comes in handy for mixing 8-channel Max/MSP or Supercollider patches from the center of the hall. This is more in the light-client-as-controller use of mobile devices (especially since this iPaq is a bit slow).

Maps and Legends: an FPS-based interface for Composition and Improvisation

An interactive multi-channel multi-user networked system for real-time composition and improvisation built using a modified version of the Quake III gaming engine. By tracking user's positional and action data within a virtual space, and by streaming that data over UDP using OSC messages to a multi-channel Pure Data (PD) patch, users' actions in virtual space are correlated to sonic actions in a physical space. Virtual environments designed as abstract compositional maps or representative models of the user's actual physical space are investigated as means to guide and shape compositional and performance choices.

Bioinformatic Response Data as a Compositional Driverp>

A software system using bioinformatic data recorded from a performer in real-time as a probabilistic driver for the composition and subsequent real-time generation of traditionally notated musical scores. To facilitate the generation and presentation of musical scores to a performer, the system makes use of a custom LilyPond output parser, a set of Java classes running within Cycling '74's MAX environment for data analysis and score generation, and an Atmel AT-Mega16 micro-processor capable of converting analog bioinformatic sensor data into Open Sound Control (OSC) messages.
