Sorry about the length of this: In outline: I tried to use musicxml2ly on
a xml file.
This ran with no error, but when I ran lilypond on the result, I got a
flood of warnings
& then a fatal error & no output. I append the (truncated) error report I
hope.
Unfortunately I do not know any way to produce a small xml that will give
this error.
The file I wanted was "O holy night" by Adolphe Adam (translated into
English) adapted
by P. Le Bas.
It came from this address:
https://www.cpdl.org/wiki/index.php/Minuit,_chr%C3%A9tiens_(O_Holy_Night)_(Adolphe_Charles_Adam)#In_English_translation.2C_.22O_Holy_Night.22
& it was the first item listed. It was available in pdf , mid , mp3 ,
xml and sib.
jsonformatter.org said it is a valid xml file. The pdf looks good. I
tried midi2ly
& the result was really weird. Please any advice?
