Capella scores use the CAPX format, while Guitar Pro 4 and compatible tab editors require GP4 files. Converting lets you open a Capella composition in software that supports Guitar Pro tablature files.
What the CAPX format is
CAPX is Capella’s score format, used by the Capella notation program to store music notation and score layout. You may receive one when a composer shares a Capella project or find it in an archive of notation files.
What the GP4 format is
GP4 is a Guitar Pro 4 file format for guitar tablature and multi-track scores. Guitar Pro and compatible programs use it to store notes, rhythms, tracks, and notation details for editing and playback.
How to convert CAPX to GP4
Online on 101convert.com
- Choose the CAPX file on the converter page and upload it.
- Run the conversion and select GP4 if prompted.
- Download the converted file when it is ready.
The page supports batch conversion, subject to the per-file size limit shown there. The conversion runs on the site’s server with MuseScore, then alphaTab and PyGuitarPro.
Offline with desktop software
Use MuseScore and TuxGuitar to convert without uploading the score:
- Open the CAPX file in MuseScore. Choose File → Export and export it as MusicXML.
- Open the exported MusicXML file in TuxGuitar using File → Import → MusicXML.
- Choose File → Save As in TuxGuitar and save the score as a Guitar Pro 4 file.
MuseScore and TuxGuitar are available for Windows, macOS, and Linux. Menu labels can vary by version; if MuseScore cannot open the CAPX file, use Capella to export it as MusicXML, then import that file into TuxGuitar and save as GP4.
Quality and compatibility
CAPX and GP4 represent scores differently, so layout, notation details, or unsupported symbols may change during conversion. Check the resulting tracks, rhythms, and tablature in a GP4-compatible editor, and retain the original CAPX file.
