This instrument and piece were developed in collaboration with David Borts for the Princeton Laptop Orchestra (PLOrk). Performers around the room play simple chime sounds, which are recorded and played back by a web-based pitch-shifting delay written in RNBO and opened on the audience members’ phones. The pitch shifting follows just intonation ratios which become increasingly complex as the retuned sounds are recorded and again retuned by other guests’ phones. Having started as simple chiming, the soundscape gradually becomes complex and self-sustaining. The instrument can be opened here.
Dmitri Tymoczko asked me to create a live video improvisation instrument to accompany his piece Glimmer. The piece is improvised based on prompts that Dmitri sends out during the performance. The video follows these themes while subtly transforming through speed changes, blur, colour saturation, and math operations on the matrix. It is programmed in Max/MSP/Jitter and controlled using an XBox controller. This recording is from the premiere performance in Princeton, and has since been performed at the World Congress on Philosophy in Rome.
I coded a granular instrument for a piece by Lola Constantino. Princeton Laptop Orchestra (PLOrk) players manipulate audio from the acoustic instruments using GameTrak tether controllers. Video of the premiere performance is available here.
This instrument resonates external sounds through a set of Karplus-Strong string models. The performer can control parameters of the sound including subharmonic divisions of original tunings that help to create shared harmonics. The instrument can optionally be controlled using a combination of a Leap Motion controller and Wekinator maching learning software to create a gestural instrument. Coded in Max/MSP.
