video-analysis and spatialisation

December 9&10 I worked with Alexander Refsum Jensenius in video-analysis and Catart again. The theme for the workshop was spatialisation. Alexander had recently been to Denmark working with Dan Overholt on the same issue so we tired out a new patch called grid they had worked on together when he was i Denmark. We used spatialisation using V-bap and video-analysis tracking my position at the floor. And then we managed to let the sound follow me when I walked around in the space. We also did an experiment in Catatrt using homogeneous sounds like pizzicato  and instead of the preset chop we tried silence segmentation. That did nor work that well because the grain got a sot of delay (The patch s looking for silent zones) The evaluation of that preset is that I can  not control the sound with my movements.

We also tried to use 2 sound corpus’s in Catart and one grid-patch and reverb for maximum expression and sound in the room. That worked well. I think we are getting nearer what we want to achieve using the space. The next theme will be how to start with an empty space record sound  in Catart in realtime and then interact with the sound in the space.


Satelite on the top of the opera


It has been a very busy but interesting process working and performing the two Satellite concerts. The first one taking place at the Roof of the Norwegian opera and Ballet April 28 and the second one in a beautiful big space at the Museum of contemporary Art. Being in charge of the planning of the operaroof I had to go into the topic of projection, choice of lenses, amount of ansilumens when the goal is to have the projection as clear and big as possible. The size of the wall we wanted to project on was 14.5x 32 meters, and sunset was around 9 pm. I decided to go for 10 pm and hoped for good weather. I also had a “bad weather plan” hiring party -tents, but fortunately I did not have to go for that. On the actual day it was some scary black cloud, but it never rained! A bit cold though about 10 degrees.

To rig up PA and projectors took more planning than I would have thought. It felt like having a concert on the top of a mountain except that we had access to electricity.  I got very good support and help from Knut Vik and lot of people from the Academy of Music helped to rig down after the concert. I had decided because of the wind not to use music but have it on a PDF on the computer. Ivar Frouberg had made me a beautiful little maxpatch that could turn pages. I worked very well and secure. I was practising with the patch for about a week, in order to be able to use the foot for turning the pages (Yamaha midi FC) as well as using other pedals (fuzz, octaver, delay) For Elektra I also had to follow the maxpatch (triggers and timing) on another computer. All this technical issues worked out very well, although I from time to time during Elektra was very busy!


To get the projection as big as we got it worked out well, surrounded by the city on the big marmoreal roof. The volcano in Elektra became huge, and I became very small, which I see as an interesting contrast. The fact that the size of the projection was so big made a better communication between the music and the video. At the most I think it was around 400 people at the roof, something I founded very good.

Thanks to Ellen Roed who took some photos!

I got a lot of press on the project, also at Østlandsendingen (TV)
