Could you build this?
Partial The UI and workflow (drop stems, preview, export MIDI) are vibe-codeable, and the tempo/key detection and separation models are open source. Getting drum and melody transcription accurate enough to be useful is a real ML and audio problem.
What it would actually take: A plausible build wraps open models such as Demucs for stem separation and Spotify's basic-pitch for note transcription, with librosa for tempo and key detection, inside a local desktop app (JUCE or Electron with a Python backend). The hard part is tuning drum-to-MIDI mapping and transcription quality, which requires audio-ML experience and a lot of testing.
