Hi and welcome to the Bome Community!
Bome has more than one product so I will address the most likely candidates
Bome MIDI Translator Pro
No web interface so I don’t think this can be done on a Browser. You might be able to use some sort of remote desktop software to accmplish this.
All MIDI ports attached to a given system are available using Web MIDI through a Chrome Browser
Bomebox has a web interface and can be managed via a web browser. There are not any tools available however to customize the web interface.
I hope this helps!
