FAQ
The bass and the kick drum are mixed together — what can I do?
Both live in the low end, so the model may bleed one into the other. Extract the drums and the bass at the same time and compare them side by side.
Can I transcribe the song from the extracted bass?
Yes — root notes and movement are audible in most songs. For densely arranged tracks, compare with the original before finalising your transcription.
