I am working on a requiem, and in the condensed score the slurs and dynamics were creating havoc as far as doubled items. I did find 2 work around’s.
Assuming slurs and dynamics are the same.
In your full score remove the slurs from, say, flute 2. Select the slurs from Flute 1, copy them and delete them. Select the first note in flute 1 and flute 2 and paste in the slurs.
Second work around; select the doubled slurs, in the property panel, change the color black’s alpha value from 255 to 0. This set the items color to transparent. They will still be there but invisible.
The condensed score will show the desired results.
Dynamics and hairpins are similar, but take extra time dealing with, as the alignment in much more complicated because you have to deal with group, ungroup, remove from group, unlink, and link. After much effort with trial and error, I have been able to achieve the results in want.
