A browser control surface for the Artiphon Orba. Plug the Orba in over USB, or connect over Bluetooth, and drive everything the official app used to: instruments and presets, per-part mix (volume, reverb, delay), tempo, key and scale, quantize. Plus a built-in looper and a piano-roll note editor.
Live: https://holofermes.github.io/orba-console/
The web app works with any Chromium browser on Linux, Windows, and Android. It should work on macOS, and does not really work on iOS.
The looper, live. Four tracks at different loop lengths (4, 8, 16, and 16 beats) play together as one polymeter groove, driven here from a phone.
 Note editor Draw, move, and resize notes on a piano roll, with grid snap, box-select, undo, and a movable loop window. |
 Instrument & FX Choose a preset for each part and set its volume, reverb, and delay, all kept in sync with the device. |
 Controller routing Point each USB MIDI controller at its own Orba part, and set the device's MIDI mode and pitch-bend range. |
 Key & scale Set the Orba's root and scale. |
 Songs & presets Load any of the factory songs, or save and recall your own snapshots. |
- Per-part instrument and preset switching, mix, tempo, key and scale, and quantize, with live two way device sync
- A browser looper that records external MIDI controllers into per track loops (the Orba's own looper only records the Orba itself), with polymeter and movable loop windows
- A piano-roll note editor with snap, marquee select, and undo
- An optional key-mapping layer for a hardware controller
Merged USB port mode disables per-part controller routing: the Orba ignores channels on the merged port and plays whatever part is active. Keep "4 separate" for routing.
The protocol is its own project: orba-protocol, a spec plus reference libraries. The optional DOIO KB16 controller firmware is orba-doio.
