In this bar, I prefer a quarter note over two eighths. How can I get this?
Select the A, press o 5 6
o is the keyboard shortcut for force duration. You need to input a different looking value (5) in order for Dorico to update when you press 6.
Great, thanks! And so quick!!
If you’ve got Dorico 4 Pro or Elements, or an iPad subscription, you can also check in Notation Options > Note Grouping for per-flow defaults for how notes should be grouped in different contexts and meters. I can’t remember off the top of my head whether there’s one for this exact situation, but there’s quite a few there that are worth knowing about (although do be aware that there can be different options for situations where notes are followed by more notes vs followed by rests) – setting those options as required once means you don’t have to force every corresponding duration in the flow.
