Quadrant is an advanced human-computer interface that utilizes four time-of-flight sensors to detect the position, velocity, and direction of the user’s hand in three-dimensional space. The onboard signal processing system can recognize gestures and other inputs, which can then be mapped to control various parameters in software and hardware synthesizers, resulting in dynamic musical expressions. For seamless integration, Quadrant features CV and hardware MIDI outputs, allowing easy connectivity with computers, analog synthesizers, and other compatible devices.
Quadrant Demo
Quadrant excels in generating computer-based music, controlling DAWs, interacting with DJ software, and performing within environments like Max MSP and Pure Data. It also allows direct control of analog synthesizers through CV or MIDI, and can even be used for creative visual control, such as VJing, LED lighting, and video synthesis. Additionally, Quadrant introduces innovative interaction methods, such as gesture recognition for left or right swipes and event triggering through beam crossing.
