I have started a collaboration with Dan Overholt, combining my interactive performance patch with Dan’s Overtone Violin. Dan is a fine improviser, so it is a good opportunity to develop and test the possibilities for combining elements from my Lars from Mars repertoire with realtime analysis-response from my academic work.

A major challenge is to reconcile fixed meter and free-flowing sheets of sound, as the meter-based material runs at sample rate, while the academic work is quite free in time and uses control level timing. I aim at using both techniques, but the synthesis is locked to to sample rate triggering, which means that the voice allotment scheme must be reworked. On top of this, I want to incorporate rubato timing in sample-level triggering, which means handling timing offsets locally in each voice. I’ll be playing a the opening concert of ArT, Aalborg with Dan, and we’ll probably end up with a release of some sort during 2012.

We did a concert at the recent re-new 2011 in Copenhagen, Denmark, and below is a video from the performance. It was held at Danmarks Radio’s Studio 2, which has a great Beyer PA (not that it shows too much in the live audio signal captured by the camera!). Live video is by VJ Voodoo Tusch.
