Quadrant is a human-computer interface based on an array of distance sensors. The hardware consists of 4 time-of-flight sensors and is specifically designed to detect the position, velocity, and orientation of the user’s hand in free space. Signal processing techniques are used to recognize gestures and other events, which can be mapped to a variety of musical parameters on software as well as hardware instruments. Quadrant has USB, CV, and hardware-MIDI outputs, so you can connect it to your computer, your analog synthesizer, or any other compatible equipment.

Quadrant Demo

Produce Interactive Art, Music, and More

What can Quadrant do? Make generative computer music, control your DAW, interact with DJ software, and play with Max MSP and Pure Data. Control your analog synths over CV or MIDI. Or think visually for unique VJ control, LED lighting, and video synthesizers. Play with gesture recognition, swipe left, swipe right, trigger events with beam crossings and more. Quadrant is open-source and Arduino-compatible, so the applications are limited only by your creativity.
