Is it possible to bracket an ossia so it’s clear in a score which part the ossia belongs to? (If it’s between two staves, it’s ambiguous if it applies to the staff above or below.)
Do you mean adding a bracket mid-system? If so, then the answer is no, but there are reasonably comprehensive controls for barline joines for ossias that should hopefully help to make it clear where the ossia belongs.
Thanks Daniel, that is what I meant. This is my specific example – everything is joined together (it’s a quartet) – is there another way of clarifying it? (If there’s no graphical way to do it I suppose I could just write “vn. 1 ossia” next to the ossia.)
Since it’s the top staff, you could put it above instead of below.
