Crossing a piano staff in one voice with an appoggiatura in another

• Apr 18, 2020 - 03:54

Hi all,

I am having a spacing issue. When I combine a note with a trill+appoggiatura in voice 1 of a piano staff while also shifting a note from voice 2 across staves (to the left-hand staff), the appoggiatura in voice 1 glitches, spacing-wise. I tried disabling Autospace, though I don't know if I fully understand that feature. Any ideas?

I suspect that the spacing rules that include both a change of staff [Shift-Alt-Down] and a post-note appoggiatura may create this difficulty. It's an unusual, but not atypical situation, especially for a piano reduction of a Classical concerto accompaniment (as this is). Thank you so much for being a helpful person (HP), even if we don't find the solution to this tiny enigma :)

Looks like a bug indeed, grace notes after a note get messed up if there is an intervening beamed note in another voice that is then moved to another staff. But - only if the main note (the one to which the grace notes apply) happens within the time span of the beam group containing the moved note. That is, in your example, the bug goes away if I break the beam into that moved F. Both because that means the F isn't beamed at all, but also because the D is no longer within the time span of that beam.

Pretty obscure set of things that has to come together to make this happen. But worth submitting to the Issue tracker for sure - would you mind doing that (Support menu above, or Help / Report a Bug, from within MuseScore).

BTW, a viable workaround for this case is to rewrite that middle voice in the bottom staff, moving the top two notes up.
