Hi All, Thanks to Aaron's wonderful hairpin colouring function I have been able to really focus in on the hairpin behaviour.
I found the issue with my score. I am somewhat dumbstruck by this. There is a call as follows at one and only point point in the score: \alterBroken Y-offset #'(0 4) Hairpin This makes the misalignment problem arise at quite a few places, but 80-90 pages later. I have recollection from somewhere that using alterBroken can have some downsides, but I do not know what. However, would this not be classified as a bug?
