Polyphonic buzz has wide spectral overlap. Four discrete bins is naive. You’re likely smearing harmonics into noise floor. Need higher resolution FFT and proper formant tracking to separate concurrent pitches.

No what I meant was your bassline, at least at the front of what you were doing was going down a fourth, like from a C to a lower G type of thing. Kind of in the same way as you would ask, can you see this picture? And I answered and said yes, I can see it's a blue car or something.

Also, it's kind of evident that the 18-second mark.

It's also me just geeking out on the small things, which is almost as bad as the AI.
