WebMIDI already has SysEx support: https://developer.mozilla.org/en-US/docs/Web/API/Web_MIDI_AP...

did you read the article?

of course webmidi must support sysEx, it's essential to work with midi2 at all. but mostly because you must parse the weird sized packet to properly ignore it.

what might show up are chrome specific sysEx messages which then leads to exploits as the article.

I tried to make a bidirectional channel from a webpage to a python script over MIDI. I'd just found that with sysex you can pack any arbitrary data that you want, that python can create virtual MIDI devices, and that Chrome can then connect to such devices.

I'm sure I'd more code than what's in my 8yo repo, but the premise is simply https://github.com/prashnts/midipacks/blob/master/midipacks/...
