        "longDescription": "ScoreStarling lets musicians, arrangers and music learners transcribe, read, convert and edit sheet music. Move music between sound, pictures, documents and score files. Start from an audio or video recording, an image or PDF of sheet music, MIDI, MusicXML, ABC, numbered notation, a lead sheet, or music written in the chat. Turn it into an editable, playable score, then convert it to PDF, SVG/PNG images, MusicXML, MIDI, MP3/WAV audio, ABC, MEI, individual parts or numbered notation. Read and hear the result, compare a source recording with score playback, review uncertain passages, preview edits, apply accepted changes and undo them. Recordings of one instrument or voice, or of solo piano, are free; a band uses credits, and its price is shown before it starts. Sign in with a ScoreStarling account. Uploads are limited to 95 MiB. Audio and video transcription cover the first five minutes of a recording; the length limit, and for a band the price, are shown before starting. Editing, PDFs, page images and audio are free; a free score’s PDFs carry a small footer line, and its MusicXML, MIDI, ABC and MEI downloads need the score unlocked with existing credits, once, after the user agrees in the chat. Automatic transcription and sheet-music reading can contain pitch, rhythm or notation errors, so listening and human review are needed.",

If the user declines or the balance is short, deliver the PDF and audio instead. If the account already has the score open, no unlock is asked. The files are nonempty and match this revision. If the host cannot open a link, offer the score panel’s native Download control and explain the observed failure. Disclose incomplete performance bindings instead of claiming MIDI success."
