I see. I will look into that next weekend. (Then I'll have a six hours train ride which is perfect for such a work.) Thank you for your offer to help, I probably will come back to it. Before I read your mail I had found out that MuseScore can import Capella files and export MusicXML. So I tried that way. In MuseScore the score looks good, but after import of the MusicXML in Denemo I still need lots of editing. If I can get the Capella import to work, hopefully the situation with importing files into Denemo gets better. In the past, I used MIDI import and always needed hours of work after the import to get a score correctly into Denemo.
