Hi smart people!
I’m trying to transpose an entire piece from E Flat Major to A Major, but when I open the Transpose dialog and make those choices, the “Apply” button deactivates. Finale refugee here, so I’m sure I’m just missing something—but what?
Thanks in advance,
David
When you click Apply, Dorico calculates the interval on the left side. The problem is that the resulting interval is not a perfect fourth. You can try to either transpose first to F or G major and then to A major, or select ”Number of divisions” and change the interval there.
Obviously you want to transpose an augmented fourth up… By any chance, are there other key signatures in your piece than Eb major? Dorico cannot transpose an augmented fourth if there is a D major, for instance. Then it must be a diminished fifth 
As I wrote earlier today on another thread, in those cases you need to transpose by chunks so that the transposition is possible. Dorico won’t take the liberty to modify a transposing interval to make it work with enharmonic intervals.
Ah! Okay, that’s… wow. So the problem isn’t that it’s a tritone, it’s that there are multiple key signatures? For a piece that changes key multiple times that seems like a bunch of extra effort (select region, transpose, apply key, one section at a time) in place of what was a single click in Finale to “transpose proportionally to end of piece.”
I see the bit in the Transpose documentation about creating unwieldy key signatures and accidentals, but… that’s just math, right? Couldn’t I just tell Dorico I trust it more than I trust myself with those calculations? 
But at least selecting individual key regions and transposing them independently does get the job done. Thanks, @MarcLarcher!
I agree Dorico could be more helpful and create those enharmonic intervals when needed (but I 'm glad it doesn’t create G#major key signatures!)
Yep. I am 100% glad I switched to Dorico, and find Dorico much easier to learn than Finale was—and, Finale handled transposition much better than Dorico does. (In one step I could tell Finale essentially, “transpose the whole piece up an augmented 4th and wrap keys around if the transposition results in more than 6 accidentals.”)
But Finale’s support had nothing on the Dorico Forum, and for this group I’m immensely grateful! 
I hear that, @davidmglasgow — this is a remarkable forum!
