MIDI-playback support

[greenbech]

Thank you for this great project! I frequently use the Working With Local Files page to analyze and transcribe music created with a music source separation model such as Spleeter or Open-Unmix (which works great! 🤘🎶)

Now, I'm working on automatic music transcription and for that use case, it would be very valuable to be able to play a transcribed MIDI file along with the audio. I'm sure MIDI-playback also would be valuable in many other contexts.

Any thoughts on adding this?

Here are some other web-based MIDI-sites for inspiration:

• https://github.com/cifkao/html-midi-player
• https://github.com/ryohey/signal

Wow those Github projects look pretty great!

So you would like the ability to use a midi file as an input source along with an mp3/WAV file?

I could perhaps take a look at a project such as https://github.com/feross/timidity

Yes, exacty. I would like the tracks in the MIDI file to act just like a waveform track with solo and mute and so on.

That project definitely looks like a great place to start!
