Smart Score overview

What a Smart Score is

A Smart Score is a structured, machine-readable version of a piece: every note, measure, clef, and marking exists as data, not as pixels on a page. The reader renders it as freshly engraved notation, and notation-aware tools can work on it. A plain PDF or scan shows the page but knows nothing about the music on it.

If you already have a MusicXML or MEI file for a piece, import it directly — it behaves as a Smart Score without using a conversion.

A version beside the PDF, never a replacement

Conversion adds a new version to the piece; the source PDF is not modified or removed. Both versions live under the same piece, and the reader switches to the Smart Score automatically when the conversion lands. You can switch back to the PDF version at any time.

Important Keep the PDF version. Printing works from the PDF, corrections with Fix a Wrong Conversion need the source page to draw a selection on, and the PDF stays the reference for checking what the conversion produced.

Where conversion starts

There are three ways to create a Smart Score, all running the same conversion:

• During import. The import wizard offers a one-time choice to convert automatically. Nothing converts unless you agreed there; adding a PDF to My Library on its own never starts a conversion.
• From the reader. Open the piece, open Toolbox (the wrench), then tap Convert to Smart Score.
• From the Trainer. Create Smart Score Layer is step one of the Trainer's prepare-record-calibrate flow.

Running and finished jobs are listed in the Smart Scores sheet, newest first, with Open and Show in Library actions. You can leave the app while a job runs; a Smart Score ready notification arrives when it finishes.

What to expect from the result

• Each conversion comes back with a quality grade from A to D and a 0–100 score (for example "quality A (94/100)"), based on how cleanly the notation was read. Treat the grade as a first signal, not a verdict — a well-formed file can still contain local musical errors.
• If your PDF matches an edition already in the Page Turner score library, you may receive that hand-engraved score instead of a fresh transcription. These results are typically cleaner than a conversion.
• When the notation cannot be read as structured music at all, conversion falls back to a visual follow map: Follow mode still works after you record a take and calibrate, but Analysis, Auto-fingering, and Transpose remain unavailable for that piece until a successful conversion.

Quotas and limits

Limit A free account includes 10 conversions. This is a lifetime total per account, not a monthly allowance, and there is no paid plan yet. When the limit is reached, new conversions are declined — every Smart Score already in your library keeps working.

Limit Conversion is designed for scores up to 30 pages and PDFs up to 50 MB. Automatic conversion at import skips longer scores. A long score started from Convert to Smart Score or Create Smart Score Layer stops with a Conversion failed message and no further explanation. Only the Convert this PDF button in Follow asks before running (Large score → Convert anyway / Cancel). Split a long score into movements with Rearrange pages in Toolbox, then convert each part.

Beta A valid Smart Score file does not prove musical accuracy. Scans, handwriting, dense textures, unusual engraving, and incomplete pages reduce conversion quality. Compare the result with the source before relying on analysis, fingering, or live tracking built on top of it.
