Scores become MobileSheets songs with the same title and PDF filename.

MobileSheets .msf song files and .msb backups are not supported — export the setlist as .mss instead.

Frequently asked questions

How do I convert a forScore .4ss setlist to MobileSheets .mss?

Share the setlist from forScore with Include Scores, convert the .4ss here, then import the .mss and its PDFs into MobileSheets.

How do I convert a MobileSheets .mss setlist to forScore .4ss?

Export the setlist via Share song list, upload the .mss plus its PDFs, and convert. Matched PDFs are embedded in the .4ss.

Why are my .msf or .msb files rejected?

Those are proprietary MobileSheets bundles. Share the setlist as an .mss list and supply the PDFs separately.

Is my sheet music uploaded to the internet?

No — files are converted locally in your browser, converted in memory, and never stored or shared. If your browser can't decompress a native .4ss file, try a current Chrome/Edge/Firefox/Safari.
