My instrument controls various audio effects in Ableton with a light sensor. The electrical components are very simple; just a light sensor going into a Teensy 2. Within Max, I have a patch that converts the information from the light sensor to information that Ableton can recognize. Then within Ableton, I can route the information from the light sensor to any effect I want to. In the video above, I designed a basic oscillating patch and made the light sensor control the rate, resonance, and frequency of a low pass filter. The sound can then be controlled by allowing less or more light to enter the sensor. Ideally, future drafts of the project will have a larger variety of sensors and a plethora of associated audio effects.
