Public evidence and practical checks

Original piano recording
191 note events describe this file, not its accuracy. There is no synchronized reference MIDI for this recording.
- Keep the original recording and the downloaded MIDI as separate originals.
- Listen to a short phrase in the recording, then compare the same phrase in the MIDI preview.
- Use the piano roll to inspect pitch, note starts, overlaps and unusually long or short notes. A suspicious note needs checking; it is not automatically an error.
- Open a copy in your MIDI editor and choose a playable instrument sound. Keep the original MIDI unchanged.
- Change one confirmed issue at a time, then compare playback with the source. Avoid quantizing the whole performance before checking expressive timing.
- Save the edited version under a different name and note what you changed.
