An experiment in AI prompt-driven development of a browser-based MIDI control surface for Behringer Flow 8 digital mixers
Connect the Flow 8 via USB to your computer and turn it on. Run a local HTTP(S) server (e.g.
httplz on a free port, e.g. 8000) serving the root directory of this repository and open a
browser at e.g. http://localhost:8000/.
Or you can use the latest version deployed at:
https://spotlightkid.github.io/flow8-web-midi-control/
The Flow 8 MIDI device should be detected automatically and the browser will ask your confirmation for accessing MIDI devices.
The software is still in beta stage and there are some known and unknown bugs and some features missing.
- The browser, in which you use this web app, must run on the device, which is connected to the Flow 8 via USB, and it must support Web MIDI. If you want to use it on a tablet or phone, it needs to support class-compliant USB MIDI devices, and you'll probably need an OTG-adapter.
- Full HD screen recommended.
- No MIDI feedback (not supported by the hardware).
- No value pick-up, so levels may jump from current value set in hardware to the value set via MIDI (the hardware does not support value pick-up mode via MIDI).
- Some (quite a few) settings can not be set via MIDI, only via the BT (mobile app) or on the hardware itself.
- Saving app state snapshots in local browser storage is untested.
- Some UI layout errors (e.g. small faders).
- Master / FX 1/2 / MON 1/2 EQ controls not yet implemented.
- FX parameters have generic names (to be done).
- Restoring mixer state from hardware via MIDI dump not yet implemented.
