GR3D Interactive MIDI Cube Synthesizer

GR3D is free 3D midi device created by Voltaine. It seamlessly integrates p5.js, Three.js, and WebMidi to deliver an experimental auditory and visual experience. Functioning solely as an output midi device, GR3D employs the QWERTY keyboard to activate an array of percussive beats, melodic phrases, and sustained tones, all elegantly represented upon a rotating cubic form.

GR3D transforms your keyboard into a dynamic musical interface. The keys '1' through '=' correspond to 12 MIDI channels, each linked to one of the cube's six faces. Press '1' to trigger a drum from the right face, or '3' for a melodic line from the top. Each face operates on a grid—adjustable from 2×2 to 5×5—animated by patterns such as diagonals, spirals, or random leaps.

GR3D is conveniently hosted at gr3d.voltaine.com, eliminating the need for a local server. To use it, ensure you have a modern web browser and a MIDI-capable synthesiser or software. Setup involves configuring a virtual MIDI port, with LoopMIDI on PC and the IAC Driver on Mac.
