Live@CIRMMT ā€“ StevenĀ Schick

Steven Schick performing Chatter/Clatter at UCSD

Last Wednesday I was involved with another concert: Pieces for solo percussion and live electronics performed by UCSD’s Steven Schick. This amazing performance was part of the Live@CIRMMT performance series, and also has another connection to the IDMIL and me. One of the pieces performed was Chatter/Clatter, part of composer Roger ReynoldsSanctuary Project, which was initially workshopped in the IDMIL as part of a project exploring gesture control of sound spatialization. We developed a sensing system using piezo-electric contact microphones on the percussionist’s fingertips, a technique which is now used in the piece.

I also drove the computer for this performance, which was running software in Pure Data (pd) which handledĀ  processing of the live sound and 12-channel sound spatialization.

TIEM databaseĀ online

The online database for the Taxonomy of Realtime Interfaces for Electronic Music Performance project is now online. It currently includes information on 45 interfaces and instruments submitted to their online survey. From the website:

We are interested in exploring the practice and application of new interfaces for real-time electronic music performance. This research is part of an Australian Research Council Linkage project titled “Performance Practice in New Interfaces for Realtime Electronic Music Performance.”

This research is being carried out at VIPRE MARCS Auditory Laboratories, the University of Western Sydney in partnership with EMF, Infusion Systems and The Input Devices and Music Interaction Laboratory (IDMIL) at McGill University.

MangoĀ sensors


During my endless search for digital compasses for use in a current project, I recently found a reference to an entirely original technique for sensing direction:

The discrete sensing elements employed in such sensor modules are generally called magnetometers and/or mango-inductive sensors.

(emphasis mine) I guess it senses the Earth’s mangetic field šŸ˜‰

Seriously though, good/cheap/fast digital compasses are hard to find – I’ve been playing around with the Robot Electronics CMPS03, but it’s crazy power-hungry and not tilt-compensated. I’ve got some Honeywell HMC6343’s with breakout boards on the way, but the datasheet says they max out at 10Hz. I’ll probably just use accelerometers for fast movements, and calibrate continuously to the slower compass.
