Here’s a little tip if you want to use a specific font for lyrics that’s not Light, Normal, Demibold, Bold or Black.
Let’s say you want to use Minion Condensed Caption (a nice choice for lyrics). Just make sure that this is the only style of the typeface installed on your system. You can have its matching Italic, too.
Then, when you select “Minion Normal” as your Lyric face, Dorico will supply the only Minion it can find.
Works on Mac, don’t know about Windows. Obviously, this means you can’t use other styles of the same face for other page furniture.
