how to use this

Separate your stems first — use Moises or Fadr (both free tiers available) to split your track into bass, melody, drums, and other.
Drop each stem into the slots below. You don’t need all four — drop what you have.
Hit analyze — each stem gets independently analyzed for pitch, key, timbre, and spectral character.
Read the report — use it as a starting brief for recreation in Ableton. Not perfect, but faster than pure ear transcription.
