Capella users may need a GP3 file to open a score in older Guitar Pro software or share it with someone using Guitar Pro 3-compatible tablature tools. The conversion transfers notation between formats, but may not preserve every Capella-specific marking.
What the CAPX format is
.capx is Capella’s compressed score format, used by capella notation software to save editable sheet music. It contains musical notation and score layout; CAPX files commonly come from Capella users sharing or archiving scores.
What the GP3 format is
.gp3 is a Guitar Pro 3 file for guitar tablature and score notation. It is useful when working with older Guitar Pro versions or compatible tablature editors. Its age and guitar-oriented layout can limit how faithfully it represents a full Capella score.
How to convert CAPX to GP3
Online on 101convert.com
- Upload the CAPX file on this page; you can add several files for batch conversion. The per-file size limit is shown on the page.
- Start the conversion and download the GP3 file when it is ready.
The page’s converter runs the conversion with MuseScore, alphaTab, and PyGuitarPro.
Offline with desktop software
Use MuseScore and TuxGuitar as a MusicXML bridge. MuseScore is free and available for Windows, macOS, and Linux; TuxGuitar is also available for these systems.
- Open the CAPX file in MuseScore using File → Open. If your MuseScore build cannot read Capella files, use Capella itself to open the file and export it as MusicXML.
- Export the score as MusicXML with File → Export, choosing MusicXML as the format.
- Open or import the MusicXML file in TuxGuitar using File → Import → MusicXML.
- Use File → Save As in TuxGuitar and choose Guitar Pro 3 (
.gp3) as the output format, if offered by your version.
Quality and compatibility
MusicXML preserves standard notes and rhythms better than a MIDI detour, but conversion to GP3 can omit Capella layout details, specialized notation, and score elements that GP3 does not support. Guitar tablature and fingerings may need manual correction, especially if the CAPX score contains notation but no guitar-specific tab.
