Grace notes at start

I think Dorico can’t deal with anything occurring before the first bar. At least, in this example, the grace notes don’t play.

So what’s the best way to do this, retaining beaming for a 4/4 bar?

You can change the pre-roll duration to allow extra time for grace notes at the start of a piece. (By default, playback time starts at the first ‘true’ rhythmic position, which is the first normal/full beat.)

Great, thanks Lillie! I was thinking it would involve creating an extra measure, or some kind of pickup cheat.
So simple!
