I've been using the string bending snippets as found on the following link:
https://github.com/openlilylib/openlilylib/tree/master/notation-snippets/guitar-string-bending
... and have just produced a strange error that I don't understand. The error says:
Drawing systems...../../benddefs.ily:203:24: In procedure ly:event-property in _expression_ (ly:event-property (event-cause right-bound) (quote pitch)):
../../benddefs.ily:203:24: Wrong type argument in position 1 (expecting Stream_event): #f
I've no idea what this means - and I can only reproduce it with quite a large excerpt from my score. The following produces the error, but if I remove any one of the bars everything functions fine. This seems rather strange to me.
Any ideas what is causing this or what I should do?
