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, 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.
ah, thanks mate. this isn't even their most powerful model - i'd recommend using the Mirelo API to access their most powerful variant or self-host on a GPU.
