I consider the time signatures function in Dorico to be superb. Maybe not a reason to switch from another software all on its own, but quite close.
The exception are the interchangeable time signatures (v.g.: 6/8=3/4). I believe the only reason to use one of these is if one wants some bars accentuated in two beats and some in three, not necessarily at the same time in all instruments and voices. Now Dorico, being somewhat less flexible than Sibelius or Finale in the rhythmic layout of each bar (for the sake of consistency, I understand, which is normally a good thing), notates everything in the bar as if only the first time signature entered mattered at all, making for many unnecessary ties and clutter even for the simplest of rhythms.
To work around this one would have to, I suppose, although hopefully I’m wrong, correct almost every bar of music by hand, or write hidden tuplets for everything, which would defeat the purpose of the feature, in my opinion. Is there any other way to do this for now?
More importantly, any ideas if we’ll see this addressed in the future? I would love to see interchangeable time signatures as an actual feature, modifying the way we imput notes in the score rather than only a graphic to paste on when wanted.
