A MIDI controller in the form of a round cage made of lasers, equipped with 32 diodes and photoresistors, eight ultrasonic sensors, and surround sound.
When a laser beam is interrupted, a sound is produced, similar to plucking a string. Depending on the height at which a laser is “plucked”, the striking strength varies.
When one walks on the instrument, they are visibly elevated on a pedestal. The receiver for the light signal is located on the ceiling and can be hung at any height. The lasers are made visible by fog. The signals are sent from Arduino to the computer where they are processed with PureData.
