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. Below is a concise guide to its operation and instructions for use, using gr3d.voltaine.com, with MIDI setup via LoopMIDI on PC and IAC Driver on Mac.
User Guide
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. Save your favourite patterns by clicking the numbered indicators in the saved patterns box at the top, then toggle to play only saved patterns by clicking the box itself. The ‘E’ key resets probability sliders to full, controlling note frequency, whilst ‘R’ randomises these sliders for spontaneous variation. Access the overlay by clicking the ‘G R 3 D’ title to adjust BPM, kick drum probability, and pattern types. Autoplay mode, activated with the spacebar, showcases animations like serpentine trails or spirals.
Installation and Use
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 (e.g., Chrome or Firefox) and a MIDI-capable synthesiser or software (e.g., a DAW with virtual instruments). Setup involves configuring a virtual MIDI port, with specific tools for PC and Mac:
On PC (Using LoopMIDI)
Install LoopMIDI: Download LoopMIDI from tobias-erichsen.de. Run the installer, launch LoopMIDI, and click ‘+’ to create a virtual MIDI port (e.g., “LoopMidi Port”). Enable autostart via the tray icon for convenience.
Access GR3D: Open gr3d.voltaine.com in your browser and grant MIDI access when prompted.
Connect MIDI: In your DAW or synthesiser settings, select “LoopMidi Port” as the MIDI input. GR3D will send notes to this port for processing.
On Mac (Using IAC Driver)
Configure IAC Driver: Launch “Audio MIDI Setup” (Applications > Utilities), choose “Show MIDI Studio” from the Window menu, double-click “IAC Driver,” check “Device is online,” and add a port (e.g., “LoopMidi Port”) with the ‘+’ button.
Access GR3D: Visit gr3d.voltaine.com in your browser and allow MIDI access when requested.
Connect MIDI: Set “LoopMidi Port” as the MIDI input in your DAW or synthesiser to receive GR3D’s output.
With no local setup required beyond MIDI configuration, GR3D at gr3d.voltaine.com offers immediate access to a refined platform for sonic and visual exploration.
