Playback error with grace notes

I’m working on (yet another) string piece, and just noticed that the grace notes used to indicate a chord are stopping correct playback.

When I look at the Play window for those notes, I see a tiny note for the grace note, and a long note for the note it’s tied to. But in the playback, it’s ONLY playing the short grace note, and not the full length of grace+regular note.

just to avoid any questions or comments about it: yes, the half notes are all shortened slightly in the Play window so that there is an actual break between the chords, and ample room for the grace notes

I have basically two identical multi-stops, on the first two beats (slow tempo) of the measure.
The first one actually play correctly, with two notes of the grace playing, then the two “real” notes playing to their full value.

but the 2nd instance of the exact same chord Dorico plays the grace notes, but then ONLY plays the very highest note, and not the one that was tied to a grace note.

in the image you can see the B tied grace note to half note.
it plays the first one correctly.
but the 2nd and even the 3rd B it cuts short, ignoring the tie completely as well as simply not playing the “real” note.

Is there a fix for this?

This is a fresh Dorico 5 file I started this week, creating the file from scratch.

To add to this, I decided to try and make a single measure file, with this excerpt, and NONE of the tied notes playback in that file. the initial grace does, and the very top un-tied note does, but the middle notes (B) don’t play at all except in the grace note pair.

Can confirm, but there are options to check out in Playback options/Timing/Grace Notes - ‘Play before the beat’ perhaps…?

I suspect that the note-off of the 1st main note is coming after the attack of the 2nd grace note on the same pitch. What happens if you shorten the first slightly in the key editor?

in the editor I’m seeing a tiny gap between the grace and the “real” note.
I suspected that the “note off” of the grace was impeding the “note on” of the real note.

but technically, since the notes are tied, shouldn’t the grace note simply be seen as a prolonging (backward) of the real note?

I can go to the note editor and drag the end of the specific grace note so that it basically pushes the real note away completely and replaces it.

but this will involve a LOT of tedious manual adjustments over the full length of this piece of music, where chords of this sort are a regular recurring thing.

I don’t understand why Dorico sees two regular tied notes (for example, across a barline) as a single “entity” in the key editor.

but sees a grace note tied to a regular note as two things?

That is a good question. I will be interested to hear what the Dorico Team has to say.

The reason is that a grace note tied to a rhythmic note doesn’t produce a single item under the hood in the way that a regular rhythmic note that shows as a tie chain is a single item. Grace notes are tied to rhythmic notes by way of special properties (similar to how rhythmic notes in different voices are tied together using special properties), and the playback system doesn’t handle this in a sophisticated enough manner at the moment.
