what I’d like is for the tuplet NOT to affect the horizontal spacing of other voices.
it’s a slightly different issue from that older thread.
for example, let’s say you have a harp gliss that lasts three beats.
there’s that heptuplet of cue note sized notes on beat one that gives you the string tuning.
simultaneously, all the woodwinds are playing three beats of rising 16th notes.
that harp heptutplet skews the spacing of the 16th notes on beat one, stretching them out to fit the spacing of the 7:4 gliss marking.
I know I could, instead, make the glissando cover a longer time, for example have those seven 16th notes cover two beats instead of one. however this will sacrifice more-or-less correct playback for the visual look.
I made a simple example, though this is a more serious issue where the notes in other instruments contain more complex rhythms that really rely on spacing for clarity.
here you can see that the first measure the harp gliss fits on 2 beats of that flute part.
But playback is wrong, with the 7 initial notes of the harp playing too slowly.
In the second example, the playback is good, except the notation is not. You can clearly see that the flute part has too much spacing on the first beat.
I did, in a post up above.
there are two examples, one with the way Dorico handles a gliss that will playback correctly but looks wrong, and one with a gliss that looks right but plays back incorrectly.
