Is it possible to reassign the numbers for note values? I prefer to have 4=crotchet. Can’t get used to ‘6’ being the number.
Yes is possible. You can customize this under: Preferences/Key Commands and search for “set note duration”.
But I suggest you generally to try to get used to the Dorico default key commands, because they are very much thought out and also consistent throughout the program. For example: little number=shorter notes, big numbers=longer notes
The default Dorico key commands for note durations (6 = crotchet, 5 = quaver, 7 = minim etc) are also used elsewhere in places where you can’t change them. For example, in the tempo popover to specify metronome marks.
Do try giving the Dorico defaults a go for a little while, and see if you can acclimatise, as you’ll almost certainly find it easier in the long run to keep track of one set of numbers rather than 2!
If you’re regularly using a variety of notation apps, then it might make sense to ‘standardize’ your numbers (amusingly/annoyingly, Sibelius, Dorico and Finale all use different values, so which of those apps you designate as the gold standard is up to you… )
It maybe takes about two weeks to break any ‘muscle memory’ and get accustomed to the new values.
“Grandad, why do you use those key values?”
“Because 20 years ago, I used to use this other app…”
