Make, practice, and share
An MPDF carries music links and practice markers inside a PDF. A regular PDF app shows the score; an MPDF viewer also plays its music.
Make an MPDF Try the complete example
1. Connect music to a PDF
- Open your PDF in the maker. Select a page on the left and work on the large score in the center.
- Add a YouTube link or audio file. Name the track and choose its start and end times. Embedded audio increases the MPDF file size.
- Place playback buttons on the score. Choose a position on the selected page and move the button as needed. You can also assign tracks by page number.
- Add time markers. Choose a music position and mark the score to return directly to that moment.
- Preview playback, then save. Your working file is processed in your browser.
2. Listen and practice
Open a received MPDF in the practice viewer, or try the complete example. Playback buttons and time markers on the page lead to the associated track or moment. The lower player controls tracks, position, and loops.
- A–B loops: choose a start A and end B to repeat a practice section.
- Key adjustment: shift embedded file audio by up to ±12 semitones while keeping its playback speed. YouTube and external URL tracks do not support this adjustment.
- Copy Note playback: select score, chords, original audio, or a mix when the file contains the required data. This does not automatically recognize and perform ordinary PDF notation.
- Internet access: YouTube and external URL tracks need a connection. Embedded audio can play offline once the web viewer has loaded. Opening the website for the first time still needs internet access.
3. Choose how to save
| Choice | Use it for |
|---|---|
| Save original | Keep the music connections and production information. Retain a creator original for yourself and send a sharing copy to others. |
| Shared MPDF | Send the finished score with music. The sharing copy excludes editable source PDFs and original markup data. |
| Score-only PDF | Save the PDF pages without music or MPDF attachments. |
| Create link | Upload a sharing copy containing only YouTube or HTTPS tracks. Anyone with the link can open it for 90 days after creation. |
.pdf and .mpdf are filename options. The save choice determines whether music is included. The .pdf extension is easier to open in ordinary PDF apps; music plays in MPDF-aware viewers.
Creator originals containing source documents, and files containing embedded audio, cannot be uploaded as public links. Download and send embedded-audio sharing copies as files. Links are not permanent storage; keep your own copy.
4. Open MPDF files from SEETO
The viewer reads playback buttons, time markers, and embedded audio from app-created MPDFs. You can download a received file unchanged. Saving it without revision preserves its exact bytes and attachments.
To revise a creator original, sign in with the same SEETO account and pass the file's creator-registration check. Shared copies remain read-only even for their creator. Files without verifiable creator information, or whose registration cannot be checked online, also open read-only.
The website supports Google-connected SEETO accounts. For Apple-only accounts, use the SEETO app to revise creator originals. Creator registration is optional for a new MPDF. If you choose it, the finished file's hash and your account ID are registered with SEETO; the score and audio are not uploaded by this step. Signing in does not synchronize your app library or Copy Notes to the website.
5. Send the file itself
Send the downloaded file directly. Printing to PDF, taking screenshots, or saving through some compressors and editors can discard attachments, music, and creator information. Share only scores and recordings you have permission to share. YouTube playback uses its official player.
