25 annotated piano performances of Burgmuller Op.100 etudes.
Each file is a multi-track MIDI:
Track 1: Full performance data (used for tokenization/encoding)
Track 2: Error annotations (pitch=0 or pitch=1 notes marking mistake regions)
The annotation file IS the data source. Track 1 contains the performance,
Track 2 contains the error labels.… See the full description on the dataset page:
