I wonder If it is possible to access MIDI ports in Emscripten compiled Pure Data / Ofelia patches.
At least the browser needs to access MIDI for that.
For that I adapted a web midi java script from this synth: https://webaudiodemos.appspot.com/midi-synth/index.html
so that you can choose MIDI in and out ports in the browser (only Chrome at the moment).

webMIDI.zip

It is my first java script, so I am sure it can be improved.

If it is not possible to use it with Ofelia / Emscripten it is perhaps useful for something else.

Here I found a project that uses C++ compiled with Emscripten and the parameters are controllable with web MIDI:

I implemented WebAudioFont. It plays an Instrument on MIDI channel 1 and a drums on MIDI channel 10.

It uses the Pure Data note on / off method with velocity 0.

I still like the Emscripten MIDI Idea, but I just dont know how to solve it yet...
