Can I obtain an audible recording of a score I just finished writing with Dorico?
In other words, can I play back the music, hear it, and capture a recording of it?

Use File->Export->Audio.

Ah! Too simple! Thanks!

Make sure the Layout you want to hear reflected in the export is on topof the Layouts list. Only the first gets exported

Am I correct that it still must be a Score layout rather than a Part layout, or has that been changed?

AFAIK nothing has changed in this regard, so this is useful information :wink:
