MIDI Extension

[Brackets-Coder]

I previously had a PR for this extension, but due to technical difficulties and organization purposes I've closed it and made a new PR using a different branch (I'm semi-new to Github, so I didn't initially fork the repo correctly).

This extension manages MIDI input. While support for MIDI output is possible in the future, I'm not planning on it at the moment. Currently, only MIDI note input is supported. Other MIDI input events return a console log. This means things like pitch bend, damper pedals, etc. will not work.

Note that MIDI compatibility varies depending on which browser you're using. If the browser doesn't have MIDI API support, it will return an error, show an alert, and the extension won't load.

I've made a sample project, but I won't add it until this gets merged because it uses localhost instead of extensions.turbowarp.org.

I'll need to remember to handle this PR

Something to note: I haven't tested the latest commit, but it basically just condenses some blocks into single blocks with inputs, and it passed all checks, so I'm assuming it works. Code looks perfect, but I can't test it right now.
