TypeError: Cannot assign to read-only property "duration"
I try to use the "ExpandChordSymbols" plugin. When I choose a rest in the pattern, I got the error, after these lines:
var e = newElement(Element.REST);
e.durationType = cursor.element.durationType;
e.duration = cursor.element.duration;
I don't want to submit an issue, because I didn't write the plugin. May be Mark Shepherd can find a workaround, or submit the issue, at his choice.
