Quadrant: An open-source gestural controller for music, art, and more

Christopher C

Demo (Attended)

The Teardown 2025 schedule is not yet finalized.
Check back here for time and location.

In this session, I’ll set up some interactive hardware configurations which demonstrate the various use cases for Quadrant:

• Computer music: PureData, VCV Rack, and other applications controlled via the USB interface
• Analog synthesizers: A modular (e.g. Eurorack) synthesizer controlled by Quadrant through the control voltage (CV) interface
• MIDI output: a hardware synth whose notes are triggered by Quadrant beam crossings (like a laser harp) from its MIDI output jack
• Daisy-chaining: By connecting the output of one board to the input of another, we can chain many Quadrants together to control a high-dimensional parameter space

Visitors are welcome to try their hand (pun intended) at making music with Quadrant.
