We provide here the evaluation set employed in our experiments described in "Towards Musically Informed Evaluation of Piano Transcription Models", published in the Proceedings of the 25th International Society for Music Information Retrieval Conference (ISMIR), San Francisco, United States, 2024. In this work, we demonstrate musically informed piano transcription metrics using transcriptions derived from three state-of-the-art transcriptions ([1], [2], [3]). To this end, we create an evaluation set that includes (1) a subset of the original audio recordings from the MAESTRO dataset [1], (2) a re-recorded version that subset, and (3) a perturbed version of recordings from both (1) and (2). In this data repository, we provide components (2) and (3).
