Dynamic change and long crescendo after a repeat causes playback error

[henkdegroot]

Issue type

General playback bug

Bug description

The attached score playback is corrupt at bar 124. When you start the playback, it sounds like quarter notes, while the bar contains a half-dotted note tied to the next bar. Playback remains like this for a few bars until it picks up the actual written note values.

Someone else tested using this score and removed many instruments and bars. The "extract" for the score still plays incorrect. However, if you remove the repeat barline in bar 1 the playback work as expected.

Interesting bug! It seems like it is caused by the change of dynamics after the repeat and the crescendo going past a certain point.

I think this would be the minimal way to reproduce. Bug is present in MS Basic and Muse Sounds, but less noticeable in Muse Sounds

@zacjansheski , thank you so much for this. I can at least work around the issue. Change the cresc. to stop before the rest and start a new cresc. at that position works for me.
