Midi in is not supported yet, i.e. you can't press a key on your connected MIDI keyboard to send a MIDI message to the worklet yet. You can simulate it with the keyboard on the left. Quoting the Help page (accessible with the "?" button on the top right):
"The MIDI IN keyboard will send MIDI messages to the worklet's MessagePort. Messages are objects of the form {type: ['noteon' | 'noteoff'], value: { note, octave, midi, frequency } }"
Using physical MIDI controls will be supported in future releases, though.

Do you have a github or a blog I can follow? I didn't see anything in the info on your site.
The blog is a WIP, I would like to blog about Audio DSP with maybe code examples hosted on the worklet editor. I just need to find the time.
My GitHub repo is cristiano.belloni, but I don't really use it - I normally use GitLab these days, and most of my repos are private for one reason or another. I'll probably open some of them, but only if I know there is interest and I can maintain them properly.
These are a bunch of demos: https://googlechromelabs.github.io/web-audio-samples/audio-w...
