I’m on Dorico 2.2 and have a grace note as the first note of my Flow. I adjusted the pre-roll in Playback Options to 0.2 seconds and hear the grace note fine on playback (using NotePerformer for playback). However, when I export the Flow as an Audio (.wav) file, I don’t hear that first grace note. Is this a bug, or how do I get the first grace note to sound in my exported audio file?
I just gave this a little test myself with a short pre-roll value and found that I did get grace notes before the first beat of the flow included in the exported audio, as I would expect. Would you be able to attach your project here? You can probably delete everything after the first bar or two and attach only that if that’s still sufficient to replicate the problem.
