Hi all–
I have a feature request: banners at the top of the screen in write, engrave, and PRINT modes (or a warning dialogue) that indicate whether or not you are printing a transposed score at concert pitch.
The scene: organ loft, 9:30pm Christmas Eve; “Midnight Mass” in an hour, trumpeters show up… and one of the two players had 2 scores that were not transposed scores. They had been printed at concert pitch. 
Organist: bolt down to office (thank God it was in the church basement!) to generate new parts and hope to God this player can pull it off. Return 3 minutes later and apologize profusely with a very red face (from embarrassment and from running up/down a combined 4 sets of stairs in under 3 minutes). Assure him it’s OK if he wants to sit these movements out; he will be paid either way. 
The backstory: I have a parishioner that is well plugged into the music scene and has professional contacts around town; he can find me a brass player last minute for Christmas (I just started new job recently and was trying to put on a school concert with 150 kids less than a week before Christmas; there are only so many hours in the day.) Great!
I generate parts about a week out from Xmas. Dec. 23rd he tells me he found TWO players; this was very unexpected since we were working with less than a week’s lead time (and this is a small town!). I stay up late generating a few more complimentary parts. Final review; looks good with incredibly little manual intervention (I love Dorico!); print; hand off scores Sunday morning; players show up Monday evening. sweat beads on forehead
Where I went wrong: (where do I start? 
) I discovered the hard way, that when you check “transposed score” it only changes the particular layout that you are viewing. It does not “mode switch” all affected layouts. Because I had generated the first trumpet part (in Bb) a week earlier and was not rushed, everything was fine. Because player #2 was a (welcomed, if harried) surprise, his arrangements were generated in a flash; I reviewed notes on the master score; switched back to transposed score and printed parts. I didn’t realize that the second trumpet part had not converted to the transposed version when I ticked that option on the master score. When I reviewed part 1, it had been converted (a week earlier) and so I was lulled into a fake sense of security.
To be clear, this is a lesson learned and there are soooo many reasons (all on my end) why this should have never happened. I do not mean to blame the development team in any way. That said; there was no warning “You are printing a transposed score at concert pitch. Do you wish to proceed?” or no colored banner at the top of print mode for me to catch my mistake. (As a quick aside; why would printing a transposing instrument’s part at concert pitch even be allowed? I understand viewing the file to correct notes if you have difficulty reading a transposing part, but why print?)
I had glanced at trumpet 1, formatting was fine-- It looked good (and it was properly transposed). Quick peek at part #2 to make sure it looked the same as #1 and off to the races. Sadly, I didn’t realize that the concert pitch/ transposed pitch toggle was layout specific and that the key signature was different. Ultimately, I think layout-specific is a great choice; but I learned the hard way. But, like I said, it would be nice if there was some kind of warning.
If nothing else-- hopefully this little story will keep someone else from falling into the same trap for their next gig.
Merry Christmas, all, and a Happy New Year!
