PDMX

PDMX is a large-scale, open-source dataset containing over 250,000 public domain MusicXML scores designed to support symbolic music processing while mitigating copyright issues. It includes the `MusicRender` extension of the MusPy library, which facilitates the handling of MusicXML files and captures additional musical details not available in MIDI format. Notable features include the availability of various file formats (MXL, PDF, MIDI) and a subset directing users to songs with confirmed valid licenses.
