Most impressive. This is what I have been looking for!

you should add a demo

Love it. I just wish i could not just save the midi but play it via webmidi on any available port.

Someone should build spotify-like UI for this and add more songs from abcnotation.com .

That's my project, https://www.folktunefinder.com . It's been going since I was a student over 10 years ago.

But I've not had any energy to spend on it in the past couple of years. It's currently mid-rewrite-in-Rust (from Clojure).

(Edit; mis-read 'Spotify' as 'Shazam' - folktunefinder is for searching not playing)

Interesting project, either way. Thanks for sharing.

good luck with the rewrite, but data-acquisition is more of a problem I suppose?
