Tangentially, I haven't been able to find any software which has reliable OCR for music scores; they tend to be just bad enough as to be useless. Was curious if any recent AI developments could be applied to this, but don't have the expertise to look into this myself. If anyone has any thoughts or wants to look into this, please feel free to email me! (link to my website in profile, which has my email)

It’ll accept images and PDFs of music, extracting the notes, rhythms, etc., so you can play it back and edit it with our built-in editor.
It uses machine learning and works significantly better than the other products on the market. There’s a bunch it doesn’t do yet, but it’s useful enough already that we launched in public beta.

I haven’t tried it but my first thought was to use something like tesseract OCR, and I found this optical music recognition (OMR) project from there.
