Berklee College of Music is offering a course in Circuit Bending and Physical Computing.
In this class, students develop the basic electronics skills necessary to do creative circuit-bending, to modify and rewire sound-making toys, and to build custom performance interfaces using game controllers and a wide variety of sensors. Students breadboard and build a custom analog synth. They develop sensor-based controllers using the Arduino and program them using the Processing language. They design and program their own interactive games and audio/video remixers. Using these skills, students will develop strategies to control a range of hardware and software synthesis systems. By the end of the course, a student will have developed their own expressive MIDI and audio control system.
