Workshop and collective performance hosted at bb15 in Linz, Austria [http://bb15.at/] on December 8th and 9th, with a performance on December 12th.

During the '∆∏ ̇·\^¬ Devices' workshop the participants built an instrument based on Arduino [https://www.arduino.cc/], the sound is generated using Mozzi [http://sensorium.github.io/Mozzi/], which is a sound synthesis software library for Arduino. Next to designing and building a working prototype, we played with interface design, physical tonal layouts for melodic scores and collective performance methods. After everyone developed a working prototype, we performed a roughly composed piece with our instruments.

On the first afternoon we designed interfaces and assembled the electronics. On the second day we programmed our instruments and practiced our collective performance.
