About CAPX
capella is a notation app from capella-software in Germany, much used by choirs, church musicians and music teachers. CAPX is the file its newer versions save scores in, where older ones saved CAP.
A CAPX is a ZIP holding score.xml, capella's CapXML: the staves with their instruments and clefs, then each system of the page with its staves, voices, notes, rests, lyrics and drawings.
Filepeek reads it with alphaTab in your browser. The score opens on white paper with every staff, grouped as capella bracketed them, and plays with General MIDI sounds, the bar it's on followed. Save as MIDI or as a Guitar Pro file.

Questions
How do I open a CAPX file?
Drop it on this page or press Peek a CAPX. The score opens with every staff and plays in your browser, with nothing to install.
Does an old CAP file open?
No. CAP is capella's older binary file, which Filepeek doesn't read. capella and MuseScore open it, and capella saves it again as CAPX.
Why does my score look different from capella?
capella keeps each system as it laid out the page, while Filepeek spaces the bars to fit your window. The notes, words and staves are the same.
Can I hear a CAPX file?
Yes. Press play and each staff plays with the instrument capella gave it, the bar it's on followed. The speed button slows it to half or speeds it up to 1.5 times.
How do I convert CAPX to MIDI?
Open it, choose Export, then Save as MIDI. Every staff goes into the MIDI file.
