System text takes care of the # of beats.
It’s important that I input this material as chord symbols, not text, so that each chord symbol transposes accurately in transposing parts.
Occasionally, this composer also writes chord symbols with four pitches, e.g.…
… which I’m now having to tackle in Dorico for the first time.
Anybody have any ideas how I might handle these four-pitch chords?
