A worked handoff example by PlayableNotes. The client-inbox situation on the page is hypothetical; the PDF reading, export, import, edit and saved files are real.
Clementi, Sonatina in C major, Op. 36 No. 1, first movement. The public-domain edition is Mutopia 804. The input was the first-movement page of the complete sonatina PDF. This page contains all 38 bars of the first movement, not an incomplete excerpt.
Actual piano PDF input · Checked PlayableNotes MusicXML export
The source PDF was genuinely read in PlayableNotes. Pitches and rhythm were checked against the official source. A spurious change from 2/2 to 4/4 at bar 5 was removed in the product before the MusicXML used here was downloaded. Source expression and composer metadata were not all preserved automatically. The source’s Spiritoso marking was missing from the exported reading.
The checked MusicXML was opened in MuseScore 4.7.5. We used the real graphical interface to add Spiritoso above the first bar, saved the editable .mscz project, and exported the two-page PDF. The playback setting produced by that marking is quarter note = 160; the source prints no metronome value there. The walkthrough shows real product interaction, not a recreated editor interface.
GUI-saved MuseScore project · GUI-exported PDF
The imported and edited MusicXML contain the same 389 written note/rest events, including 333 pitched notes. No events were added or lost. Repeat boundaries also match: the backward repeat at bar 15, forward repeat at bar 16, and backward repeat at bar 38.
The official first-movement MIDI contains 333 written notes. Expanding its two repeated sections gives 666 performed notes; the edited score’s MIDI matches their pitches and onsets in beat units. Written note/rest durations were checked separately through MusicXML because synthesizer articulation can shorten sounding durations.
The audit MusicXML and MIDI were exported using the official MuseScore command-line exporter from the same project saved in the graphical editor. This verifies the saved score; it is not presented as footage of a graphical edit. All visible edit/save/print proof comes from the real graphical interface.
This single checked example does not establish universal reading accuracy or unchanged page design. Source dynamics, composer credit and other expression details still need editorial attention. MusicXML is an editable handoff, not a promise of a perfect facsimile. The source edition remains available for comparison.
MuseScore is a separate notation application. PlayableNotes reads the piano PDF and exports MusicXML; this example demonstrates continuing that file in another tool.
