Feature Request: Native Music Notation OCR Support in Adobe Acrobat

Hello Acrobat Team,

I am following up on a feature request I originally submitted in October 2023 regarding Music Notation Recognition Within Acrobat OCR. I am glad to see renewed activity on the thread and wanted to provide a clearer, more implementation-oriented explanation of why this matters and how it could realistically work.

I have used Adobe products professionally for over twenty years. Acrobat remains best in class for OCR, document structure, and publishing workflows. That is precisely why this limitation stands out and why Adobe is uniquely positioned to explain it.

Feature Requested

Native support in Acrobat OCR for musical notation, including recognition of staff systems, notes, rests, clefs, key and time signatures, dynamics, articulations, and tempo markings as structured musical elements rather than decorative graphics or generic text.

Current Limitation

When Acrobat OCR processes sheet music today, it breaks musical meaning:

• Staff lines are interpreted as underlines or separators
• Notes are replaced with system fonts or text characters
• Dynamics and symbols lose semantic context
• The resulting PDF cannot be meaningfully edited, preserved, or reused

I have encountered this repeatedly while editing and producing professional music books that include engraved sheet music.

Existing Tools and Gap

There are standalone tools such as PhotoScore Ultimate and ScanScore Professional that attempt music OCR. Their recognition accuracy is inconsistent and requires extensive manual correction, even with clean source material. They also operate outside modern document workflows.

This is where Acrobat could clearly lead.

High-Level Implementation Concept

This does not require Acrobat to become notation software. A viable, optional OCR mode could include:

1. A selectable “Musical Notation” OCR option alongside language recognition

2. Detection of staff systems as structural anchors rather than flattened graphics

3. Symbol recognition constrained by staff position and spatial rules

4. Preservation of relative horizontal and vertical relationships

5. Output to a tagged PDF layer and or optional MusicXML export

6. Fully optional behavior so standard OCR remains unaffected

Acrobat already excels at layout fidelity and semantic structure detection. Musical notation follows strict visual grammar similar to text and tables, making this a natural extension of existing capabilities.

Accessibility Impact

This feature has meaningful accessibility implications.

Properly recognized musical notation could allow tagged PDFs, zoom tools, and assistive technologies to interpret sheet music in ways that are currently impossible. Today, visually impaired musicians and students are effectively blocked from accessing scanned notation content.

Closing

With current AI driven layout analysis and pattern recognition, this feature feels less speculative and more inevitable. Even a foundational implementation would make Acrobat the strongest bridge between scanned sheet music, accessibility, archiving, and professional publishing workflows.

I would be happy to provide real world sample PDFs or clarify technical expectations if helpful.

Thank you for your continued work on Acrobat and for considering this request.

Best regards,
John White
