Let me know if you have any feedback! Issues/PRs welcome.

Note that Android is still a bit finnicky about connecting MIDI devices (using USB-OTG); After accepting the permission request, you might have to go through some permutation of refreshing the page and unplugging/replugging the cable to get it to work.
