Force duration in tuplets problem

I am inputting Chopin’s A flat Impromptu from a facsimile and I’m struggling with the following passage:


I try to force the length of the up-stem crotchets in the RH but however I do it, Dorico shows a tied note as follows:

This seems too complex and Chopin’s written intention is much clearer.
It was awkward to place the long notes in the up-stem voice on the third triplet quaver, but I found a way to do that. However, forcing the crotchet length to remove the tie has eluded me. It seems that forced length doesn’t work in tuplets.
Can anyone suggest a solution?
(I imagine the F flat crotchet that runs over the bar line at the end of bar 29 may simply have to be tied over, but I’d like to force the ties from the others if possible.)

You can achieve this by nesting the quarter notes from the upper voice within tuplets and hiding the rests (the third eighth note of the triplets is a 2:1 eighth note tuplet).

Here’s another way to cheat, but charles’s soution provides the quarter note on the final eighth pulse of the measure; so I’d steal that were I to rework my solution.

Naturally I’d hide the 12/8 and adjust the tempo.

You can get the graphic look by making the upstem voice a sequence of 3:1q tuplets (each tuplet has two quarter rests and one quarter note). Each one takes up the same amount of time as one regular eighth note triplet.

Here’s what it looks like before I removed rests and hid tuplets.

The playback won’t be exact, because each “quarter” note has the same duration as the eighth note underneath.

Edit: Looks like others had a similar idea while I was putting my file together.

Your solution is more elegant than mine as it avoids the use of nested tuplets!

Just for fun, one solution with correct playback (with a hidden tie accros the barline and a hidden note). But of course, it would be easier to just lengthen the fake quarter notes in the Key Editor:

[Edit:] Just thought about it again: no need for hidden tie and note, everything can be done across the barline for this playback version!

I knew there was some way to accomplish this with playback, but the math made my brain hurt!

Amazing! I did not know or imagine that one could place 3 triplet quarter notes in the space of a single quarter note. So even when I followed the advice above, I hardly expected it to work because it doesn’t make a lot of sense to me in terms of timing. However, the appearance is exactly what I’m aiming at.
The key to this as @charles_piano and @asherber make clear is to use a n:1 tuplet. I was using 3:2 8th note tuplets.

Thank you very much to @charles_piano , @Derrek and @asherber for solving this so quickly. As I say: amazing!

Additional:
I now discover that the Dorico documentation on tuplets is rich and extensively illustrated. Note to self: always read the docs thoroughly instead of making assumptions: the Dorico team have likely covered all eventualities.

Both are amazing solutions!!! Bravo!
