Wow, this works way better than I expected. Fed it "Shimmer and Out" by Lotus, the intro of which is just a pretty simple guitar riff based around triad shapes - but it's the kind of thing I've seen Chordify just mangle. This produced a transcription that sounds 1:1 to my ear.

Could totally see myself using this as part of the tools I use to learn music - and I could also see someone eating Chordify's lunch by hooking up a model like this and doing note-level theory analysis in addition to whatever spectral analysis model they're using.

https://kyutai.org/blog/2026-07-10-muscriptor/ says We're releasing MuScriptor, the best open model for multi-instrument transcription to date, created in collaboration with Mirelo. Give it a recording: pop, classical, metal, jazz, whatever, and it transcribes the notes played by every instrument into MIDI, without needing to know in advance what instruments are present.

Wow! Perfectly did the whole intro of 'In the end'!
