…and I wish to add a slur from the first high ‘G’ to the immediately following F#. I did the select followed by cmd-select and pressed ‘s’, and the slur ignored the lower voice:
Were both pitches highlighted when you selected them? I tried this just now, and the rhythmic overlap didn’t cause any problem. I know this doesn’t answer your problem, but at least you (we) know it’s not the rhythm that is the culprit.
As you mention Daniel if you put the stem down voice f at ⅛ after the upstem g the cross voice slur works but if you shift the f by 1/16 backwards it disappears…
One could of course question what the slur wants to indicate and if it is needed. As the top note is still ringing after the bottom note starts it is sort of an “implied legato.” even without slur.
Yes, it seemed to me to have something to do with the tie in the lower voice. If I break that tie, then I can slur the first G to the first F#; if I then add the tie back, the slur snaps back up above the staff.
Yes - I tried it, and as soon as I lengthened the lower pitch the slur jumps up. A work around is to put the tied note in another voice. As the image shows, it works. Why is another matter…
Perhaps, but imagine a line made up of alternating overlapping and non-overlapping notes (i.e., some held over, some not) which you might want a slur over. Makes no sense to have to break the slur every time two notes overlapped.
