Just tried this out. The stem isolation is pretty cool, but looking at the spreadsheet of chords it spit out, it seems to miss out on a lot nuances of chords. The song I used to test was Again by Mac Ayres[1], which I compared to some tabs I found on Ultimate Guitar[2] which I've played and sound very accurate.
The main 3 repeating chords, Ebmaj7 Gm7 Abmaj7 are close to what Fadr spit out, but it missed them being 7 chords. It gave D# Gm G#.
Getting a little spicier with chords, there's a move where the Cm7 has the bass move down a half-step to Cm7/B. Fadr wrote it as a single Cm chord for the whole thing. That's the kind of thing that can be tricky to figure out. It kinda seems like it doesn't know anything outside of straight-up major and minor chords at all? Cause I don't see a single 7 in the entire spreadsheet, and that's not even that complex of a chord.
Still a neat tool, and trying to learn off of a stem track would probably be easier than the whole ensemble. But I think there's tons of room for improvement in the space.
