Truly, I’m at my wit’s end here, any and all help in resolving the issue outlined below would be much appreciated. I’ve spent three full days this week trying to troubleshoot problems with very little progress to show for it.
The specific problem concerns the playback alignment of the A9sus chord (keyboard part).
In the Play editor, I can clearly see, and hear in playback, that the left hand is triggering earlier than the right, even though this shouldn’t be the case.
With thanks to @YourMusic.Pro for verifying the issue, and in case this is helpful to others working in swing time, Daniel confirms there is a playback bug at work here.
Dorico is not correctly detecting the case where an off-beat note longer than the swing duration is preceded by a rest.
Daniel suggests the following workaround:
In the meantime, you could consider disabling swing for that bar using the Shift+T popover and Alt+Enter to create a rhythmic feel change on just that instrument. You could then fix up the positions of the notes in the Key Editor, and re-enable swing in the following bar with another local rhythmic feel change..
As ever, the helpfulness and responsiveness of the dev team is stellar.
