Older notation or tablature software may require the Guitar Pro 3 format, while a score made in MuseScore is stored as MSCX. Converting lets you share the music with GP3-compatible programs, but the score may need checking after export.
What the MSCX format is
MSCX is MuseScore’s uncompressed, XML-based score format. MuseScore creates it when saving a score in its native format; it stores notation and score data for editing, rather than a rendered page or audio file.
What the GP3 format is
GP3 is the binary file format used by Guitar Pro 3 for guitar tablature and musical notation. It is useful when sharing scores with older Guitar Pro releases or other software that supports GP3. Its older format supports fewer features than current score formats.
How to convert MSCX to GP3
Online on 101convert.com
- Upload the MSCX file on this page and select GP3 as the output format.
- Start the conversion, then download the resulting GP3 file.
The page supports batch conversion; its per-file size limit is shown there. The conversion runs on the server with MuseScore, then alphaTab and PyGuitarPro.
Offline with desktop software
Use MuseScore and the free, open-source TuxGuitar, available for Windows, macOS and Linux. MuseScore does not export GP3 directly, so pass the score through MusicXML:
- Open the MSCX file in MuseScore and choose File → Export. Export it as MusicXML, usually with the
.musicxmlor.xmlextension. - In TuxGuitar, import the MusicXML file using File → Import → MusicXML.
- Export the imported score using File → Export → Guitar Pro, then choose GP3 in the format options and save.
Menu names and available export formats can vary by software version. Confirm that the export is GP3, not GP4, GP5 or another Guitar Pro format.
Quality and compatibility
MusicXML acts as an intermediate format, so inspect the GP3 result for instrument assignments, tablature positions, repeats, tuplets and other notation details. Page layout and playback settings may not transfer exactly, and GP3 cannot represent every feature supported by a current MuseScore score.
