MacOS, CB 15.0.10 (but this bug has been there since the new score editor was introduced).
I’m posting a video of an issue that I have mentioned before whereby when nudging notes in the score editor using the keyboard (Option + up/down) can stop working properly and the key editor and score editor lose sync.
I have been trying to spot a way to reproduce this for months, but it just happens randomly in all my projects after a while of editing, so I can’t provide steps nor do I feel a project file would shed any further light. I could start a fresh project with 1 track in the score and after continuous editing this would occur eventually.
As the video shows, when this occurs, dragging a note works all the time but using nudge is broken. The midi updates, the info line with the note name is correct, but the score is not changing.
A clue may be something to do with highlighting/UI focus. When you click on the note it highlights orange, but as soon as you nudge, the highlighting stops and it takes a few clicks to be able to highlight that note again.
It can start working again on closing/re-opening the score editor - but not always.
It might seem a small bug but this has led to errors creeping into my scores. Acoustic feedback on nudging (which is still outstanding) would help mitigate this.
