What about Y-offset (e.g. <http://lilybin.com/yb5u35/6>)? Where does that go?
Hello Kieren.
Look at this:
As you can see, the result is the same if I set "2" or "0" for the Y-offset property.
This means that there's not a way to know how to shift the bracket +2 staff spaces (or any other specific value) above its *calculated position*, because there's a hidden (and unknown) offset. Similar problems happen with staff-padding, outside-staff-padding etc.
As you can see too, in the previous snippet, extra-offset shows the correct behavior. But using extra-offset has the disadvantage that "correct values for the repositioning have to be worked out, often by trial and error, for every object individually"
Consider too that the behavior of all these properties (except for extra-offset) seems different if I use \offset instead of \override or if I switch from 2.18 to 2.19 and vice-versa.
Then I would consider the OttavaBracket interface *broken*
Maybe I'm wrong and I ask all again the starting question with an added token:
How can I shift up the ottava bracket exactly TWO staff spaces above its calculated position in the first way suggested by the documentation ("other objects will be moved automatically if necessary to make room ") ?
Best,
