Dedicated route: this tool uses the model path selected for this workflow.
After inference, Beat This final0 writes a valid fixed tempo or beat-by-beat tempo map into the MIDI while preserving every event's position in seconds. If valid beat evidence cannot be produced, the task fails instead of delivering MIDI with the model's default tempo.

Use cases

Turn a complete recording into editable notes, drum hits, tablature or a chord timeline.
Compare the model output with the original audio to review onsets, boundaries and source assignment.
Move MIDI and time-aligned tables into a DAW, notation editor or downstream analysis workflow.

Workflow

1Upload the complete supported file rather than a short test fragment.
2Choose the profile that matches the instrument or task, then adjust only the controls exposed by that official model.
3Review the preview against the original audio and download the result files from the completed task.

Pre-flight checklist

Do not send a dense full mix directly to a solo-instrument model; separate the target stem first when needed.
Start with the published defaults and change thresholds only when the preview shows a specific boundary or false-note problem.
Treat transcription as an editable draft: timing, note length, fingering and chord boundaries may still need musical correction.
