Sources and credits
The benchmark contains rendered musical excerpts and their isolated note references. Instrument recordings were selected by pitch, resampled, cropped, scaled and mixed according to the score. The editing task applies fixed gain, pitch, timing and tuning changes to these same notes.

Scores
Most score editions were selected from the no_license_conflict subset of PDMX, by Phillip Long, Zachary Novack, Taylor Berg-Kirkpatrick and Julian McAuley. The selected score records identify CC0 or public-domain editions; PDMX's dataset attribution is retained here. Piece titles, composers, original license links and excerpt transformations are listed in score-credits.json.
Two excerpts use direct public-domain Mutopia editions:
scns_eval_v3_029: Johann Sebastian Bach, BWV 871, from Mutopia 316, a Bach-Gesellschaft edition. The excerpt's timing is scaled by 20/11.scns_eval_v3_051: Ludwig van Beethoven, Piano Sonata Op. 13, first movement, from Mutopia 299, identifying the G. Schirmer 1894 / Berners 1908 edition.
The corresponding original MIDI files are included beside this notice. Score timings and crops were used to render the benchmark recordings; isolated-note and mixture audio remain aligned. Use the evaluation.json distributed with this release when scoring its audio.
This release uses Swagbass for the bass recordings. Project16 Rickenbacker recordings are not included.
