Hi Martin:
I am not sure if I was doing the steps correctly (was working with Frescobaldi 3.01 and LP 2.19.42; have since updated to 2.19.80)
Am trying the steps again; in 2.19.42 I got no output
- Menu File > Import MusicXML
- Select a MusicXML file
- Execute musicxml2ly
Expect: The import dialog disappears and a new code window with the generated ly file should open
Actual: The import dialog disappears but nothing else
In 2.19.80 LP is running (and says it can take some time...), so will post another after the process completes ....
