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:
& it was the first item listed. It was available in pdf , mid , mp3 , xml and sib.
& the result was really weird. Please any advice?
