Concert, Sound of Mu, January 25

The stage was set for an exciting encounter between two live electronic musicians of international standing at Sound of Mu on Tuesday January 25.

Diemo Schwarz from IRCAM held a workshop in advanced synthesis and signal processing at NOTAM in the end of January.

Diemo Schwarz is one of the leading figures within the live electronics field, and he has developed a number of signal processing tools, including Max/MSP patches such as FTM and CataRT. It was a pleasure for me to be able to play a concert with him again.

The concert was organized by me in collaboration with NOTAM, and Cato Langnes was the sound engineer. In addition to improvisations by Diemo and me we

both played a solo piece each. I played Thomas Dahl’s piece No Reason Aftermath. It was a great atmosphere at the venue.

Diemo is using the iPad as a control function for CataRT, as well as a pressure-sensitive MIDI-controller which controls the dynamics. It works so well with the iPad. He can play it like a separate instrument, away from the computer, using the accelerometer.

I had my first experience with real-time video/audio improvisation on my stay in Bergen  January 15-17 th.

Being able to have space at BEK Mattias Arvastsson and I worked on Victoria Counting II as well as  real-time improvisation together. I also got to meet Trond Lossius at Bek Jørgen Larsson at Lydgalleriet to discuss a project for the Autumn. More about this later. Fortunately I got to see see the opening of the exibition “Composers in Space” at Lydgalleriet as well as the exibition Looking is Political at Bergen kunsthall the same evening. img_4304

The electric guitarist and composer Thomas Dahl from Bergen  is also one of the composers in my project. We luckily now founded time to work together, and trying out some sound material in live and guitar rig.img_42971

Max/MSP from Cycling74 facilitates real-time manipulation of the sound signal, a feature that provides me with tools for experimenting with sounds and playing techniques in an interactive manner. In order to make own patches for improvisation, and to understand the “personality” of Max/MSP I have this autumn taken classes with Alexander Refsum Jensenius in Max/ MSP. I will continue working on this issues as well as discussing it with my main supervisor Ivar Frounberg. He is doing a FOU research on Max/MSP at the Norwegian State Academy of music.
