Invisible Territory

In this project, Ralph Muhlberger and I explored issues of developing a sonification of the game of Go, and then adapting the sonification for use in an interactive performance piece featuring Shakuhachi, the Japanese end-blown flute, as a primary instrument for interaction and as a sound-source for the sonification. Our approach to sonification seeks to establish a mapping from data to sound which preserves the symbolism and the aesthetics of the game, as well as present the data embodied in a specific game record in a form that is as transparently comprehensible as possible. The performance incorporated live improvisation by a human performer interacting with a sonified game of Go. A research paper and a performance were presented at Australasian Computer Music Conference in 2005.

You can hear a recording of the performance below, and read the full paper here: Invisible Territory: Sonifying the Game of Go.

SimpleNI Processing version of OSCeleton

A quick post to share a little bit of code I tweaked on the weekend. I’ve been experimenting with a Kinect sensor for gestural input into Max/MSP, and especially need skeleton tracking. I got OSCeleton working, but found it a little unstable, and I didn’t really like having to run X11 just to get a visual feedback display. Ferhat Sen’s OpenNI2OSC Processing patch was the next step, and by combining it with the SimpleNI Processing wrapper library, I managed to get a full skeleton tracking to OSC system in Processing, that seems pretty stable and eliminates the need for X11.

The output is fully compatible with the standard OSC output of OSCeleton (at least it worked identically with an existing Max/MSP patch I had running with OSCeleton). However, it only supports tracking 1 user at the moment, and it doesn’t support kitchen studio or quartz composer OSC modes.

No doubt there’ll be updates and if this doesn’t find a home somewhere else, I guess I’ll put it up on github, but here it is for now. Props to all who’ve forged this path – looking forward to where it leads us!

Hathira Sama play Senegal!

After a fantastic trip to the Fes Festival of World Sacred Music in June, Hathira Sama have been invited to play at the Sufi Festival of Unity in Senegal in January! Full details of the gig are here. We’ll be playing our main concert on Goree Island, a 20 minute ferry ride from Dakar, at 7:00pm on Wed 5 January, with the soulful Amandou and Miriam playing at 9:00pm the same night.

Also on the festival line up are Kora master Toumani Diabate, Senegal’s favourite, Ismael Lo, and our friend Ali Keeler’s group Al Kauthara from Granada. We’re feeling very honoured to have been invited by Sidi Ibrahim Tijani, and to be in such distinguished company. We’ll be playing another gig earlier in the week at the Festival venue in Dakar. We’re looking forward the journey – stay tuned for more news.
