Why "letter" (and not A4) is the default page size for instrument parts?

I dream of a world where my annual high school musical arrangement jobs look like this:

All the kids play from an iPad with Dorico

The conductor tells me after one rehearsal, that the trumpets need a lower version, while a violin kid makes a comment for me that he would like have bowings excluded

On the weekend, I Open Dorico, Open the arrangement file and all the comments and suggestions are there.

I make changes to the trumpets, write a high trumpet voice into some keyboard, delete the bowings, hit save.

Next rehearsal, everything is perfectly up to date on each stand.

But honestly, I don’t even need a „big other“ - just last week I was having rehearsals and used my iPad to quickly mark things either I or the ensemble should improve.
If I could have done these drawings directly in the Dorico app, and then open the file on my desktop or laptop to go over them - I would be a happy man! (This and cutout scores… :wink: )

I suppose that when in-place editing is a reality, which I wish for too, you could use a shared Dorico file via iCloud (or others), which would updates to be pushed to the other iPads.

IIRC Harry Connick, Jr. has a (custom) system like this that he uses with his players. Knowing how thoroughly the Dorico Team keeps abreast of the competition, I suspect someone there is already aware of it.

Harry’s copyist is a close friend of mine, and I used to sub in Harry’s big band on alto back in the mid-2000s. It was really cool system where everyone had their own monitor, foot pedals to control it, and everything was run off a server. I actually talked to his copyist right after the Dorico iPad version was released just to see what they were using now. The band is much smaller now than it was back then so they all just use large iPads with ForScore. All the files are accessible through a main Dropbox account. They have bluetooth foot pedals too but he couldn’t remember what the brand was when I talked with him. Everything is in Finale. Harry writes directly into Finale and my friend handles all the part formatting, PDF creation, Dropbox management, etc. (He’s a great saxophonist as well.)

I still do not understand Dorico behaviour. If I start a new project, Dorico starts it with A4 paper size. If I try to print, I see there US Letter again. Why there is no option in Settings-General just to choose your default paper size? No matter what I choose -Automatic, International or North American, the output is the same - US Letter


In the print preview you see the default paper size of your default printer. On my system it works like that. So if your default printer is Microsoft to PDF for example you have to change the the default paper size of that printer in printer settings of Windows.

If you check it in write or engrave mode you should see the correct paper size. Even if the print preview is not correct the printing result will be like write or engrave mode.

Thank you for your answer. I am on macOS. Usually I export my scores as PDF. But I am still not comfortable with Dorico behaviour. Dorico project is set to A4, but Print page shows still US Letter. Is it a bug? Preview on this page seams to be in A4 ( I guess) and it seams it exports it as A4 as well. So WHY Dorico shows there US Letter? It is very confusing!

When you’ve set the layout to “print” a physical copy, rather than export “graphics” like pdf (please make sure you’re using Dorico’s in-build graphics export for PDFs, you’ll get better results) then the paper size (paper, not page - that’s set for the layout in Layout Options) depends on the printer model that’s selected.

Does your selected printer default to Letter, by any chance?

We had the same discussion years ago, and did not find a solution.
In my case I have the same “symptoms” as above but my HPLaserJet is set to default to DINA4 (printer’s own menu). In macOS all my printers are also set to paper-size DINA4. My Dorico projects all start as DINA4, still in Print Mode I see this (to me) annoying Letter format. I know, it doesn’t matter, as it will not use Letter in printout. Still after probably 1.000 Dorico projects my routine is in Print View to change every Layout to DINA4 and Custom Scale to 100% manually. I like things to look perfect…

Hope I understood you right. If I open some lets say PDF or PNG file on my mac and press Command + P, in a preview I see always DIN A4 selected. So I guess my printer default setting is A4. As I said before, whe I set a new project in Dorico, I see there A4, any way in Print menu of Dorico always - US Letter

Thank you, good to know I am not alone here😊

@mipi additionally: printers have own interfaces, also web-interfaces, where you can setup the defaults of the printer.

On your Mac. If you print to PDF and the thing that you want to print is not A4 but let’s say a photo. What preview do you get? I wonder if there is a default PDF print setting that is a letter. So is in Windows.

If I understand you correctly, if I set the project to A4 and then export it as a graphic PDF, the default setting there is always US Letter, but the preview appears to be A4. If I change this setting to A4 and then back to US Letter, the preview updates to US Letter. I will probably never understand what is there going on.

If you export via Dorico’s builtin PDF function, it will use what is in Layout Options. The printer driver has no effect.

My point is that on Windows (at least on my system) the default Microsoft print to PDF setting (a Windows setting) affects the preview in Dorico print graphics PDF. If I have a project and layouts are A4 but the Windows printer setting is letter, I see a letter preview and when I change the Windows printer setting to A4 I get a Dorico preview in A4.

So I wonder if there is an Mac iOS setting that affects the preview in Dorico. I don’t know how that works with iOS but maybe you can find a print to PDF setting in Mac iOS (not a Dorico setting) and change that to A4.

The preview in Dorico does not influence the printing result. That will always follow the layout settings. Only the print preview is not correct. Write en engrave show you the A4.

Have you adjusted this setting in general preferences? This will dictate whether or not Letter or A4 is the default:

I did - no difference. So I didn’t understand at all what this setting is for…

In macOS print to pdf is built in. And it is always set to A4
