[MU4 Issue] Incorrect repeat when section break is present

[SamYeh]

Describe the bug
When a measure has both a right repeat sign and a section break, followed by more or measures, the pause for the section break is included in the repeat.

To Reproduce

Play and observe that there is a 3-second pause after the first two bars have been played once.

Expected behavior
The first two bars should be played twice without pause in between.

I’m pretty sure this has always been the case. I myself have to do one of 2 things for this, those being:

1. Set pause to 0 for section break(like if I have repeats and attaca)
2. Place the section break one measure after the repeat and set the measure invisible in measure properties(like in the development and recapitulation repeat of a Mozart Sonata)

[SamYeh]

But is that the expected behavior, though?

[DaddyLudwig]

I’d say yes because it was like this in 3.6 and I’ve never seen talk about changing the behavior of the section break on repeats, just the 2 workarounds for it I mentioned.

Definitely not intended, but yes, it's a bug in 3.6.2 as well. There have actually been quite a few reports of this and some attempts made at coming up with fixes, but no success yet.

As mentioned in https://musescore.org/en/node/32696 I'm willing to try and take this up again now that MPE is starting to settle down. The RepeatList logic already contains some preparation information on when the pause should be applied, but we still need to look into how to tie that information in with the code that generates the playback information (which in MS3 also meant that first the TempoMap needed to be made repeat-aware).

[BanjoJake]

Also happens using loop playback without repeat bars, if measure ends in a section break.

Happy Friday, March/1/2024... that bug is still nagging isn't ? I'd think 10 years is a pretty good period to have it figured out... luckily I dont ran into it often, but today, I did - https://musescore.org/en/node/32696

Perhaps the newly added TempoMap::pauseSecs can help to fix this issue.
