Orpheus PDF Utility – a free tool to help tidy up your sheet music file names.

If you’ve ever scanned a stack of paper sheet music, you know what happens next: a folder full of files named Scan_001.pdf, Scan_002.pdf, Scan_003.pdf… and a lot of effort to manually rename them.

I built Orpheus PDF Utility to fix that! Simply point it at a folder of scanned PDFs, and it will automatically extract the title and arranger, and rename the files in your chosen format. Perfect for organising digital sheet music libraries for use with Orpheus sheet music reader app.

How to Use

1. Download and install the app (Mac only for now)
2. Select your folder of scanned PDFs
3. Select the filename format you want (Title.pdf, Title – Arranger.pdf, Custom)
4. Click “Run” and watch the magic happen

The app reads your sheet music, and retitles the files. No more manual renaming – hooray!

How it Works

Orpheus PDF Utility uses AI to read the text on your scanned sheet music and figure out the title and arranger. Here’s what that means for you:

• Your files stay on your computer. The app sends an image of only the top (title) section of the first page of each PDF securely for analysis – the sheet music files never leave your own computer. This should assuage privacy and copyright concerns.
• Free for casual use. AI costs are covered for renaming up to 10 files at a time. If you have a larger library, you can add your own API key in Settings to process unlimited files. API costs are very low (~$0.002 per file)
• It’s pretty good but not perfect. AI does its best, but handwritten titles, unusual fonts, or poor scan quality can trip it up. Always give the results a quick check before you’re done.

Couldn’t I just ask ChatGPT / Claude / Gemini etc to do this for me?
You could, but it will be less accurate and far more expensive and time consuming! Orpheus PDF Utility is purpose-built for this very specific job. So it understands sheet music publishing norms (eg position of the various text elements on the page), can verify and correct it’s findings (eg against known lists of arrangers), and has logic built in to handle things like capitalisation, punctuation etc. It’s also heavily optimised to do this job efficiently (eg processing just the relevant part of the file) which very significantly lowers the processing time and AI usage costs.

It has gone through iteration over the years, but has always held true to the original vision; a minimalist sheet music reader that just does one thing, really well.
