How do I enter these triplets into MuseScore?

I'm a total beginner with all things music theory, so I figured I'd ask.

I'm trying to enter this into MuseScore, but the triplets in the last two bars are confusing me. If I try to enter them I get these extra rests. What am I doing wrong?

Edit: I am able to make desired triplets if I make some new measures in 2/2 and 4/4 time. But I'm wondering, why can't I make such a triplet in measure 52? 52 is in 2/2 time. All I can think of is that MuseScore doesn't like the staves changing time signatures separately. Any idea how to work around this? FYI: I am using MuseScore 3. I realize this is out of date, but I can't stand the way dynamics work in MuseScore 4.

• I am equally confused. Entering these triplets should be straightforward: Select duraction 1/2 and press Ctrl+3 to enter a tuplet of total length 1/2. Then enter the first three notes. Then again select duration 1/2, press Ctrl+3, and enter the second group of notes. Could you possibly share with us step by step how you enter these tuplets, and when the problem starts to appear?

• I bet the problem has something to do with the fact that each staff changes time signature at a different moment. Feb 22, 2023 at 8:58
• That looks like what a less-than-smart DAW will do if the notes & score prefs aren't quantised Feb 22, 2023 at 13:19
• The software thinks you need an extra 1/16 + 1/64 + 1/256 + 1/1024 ≈ 1/12 of a measure in the "triplet tempo", which is equivalent to an extra 1/8 note in the "base tempo". No idea why, though. Feb 22, 2023 at 16:21
• As Elements in Space implies, MuseScore may not be able to handle Strauss's unusual combination of time signatures. I wonder what Strauss thought he gained by writing the soprano in different time signatures from the orchestra here. (In the 2nd to 4th bars of the excerpt.) Feb 22, 2023 at 18:36
