unwanted colour converting: 100k -> rich black

[DoubleSix]

Now I’m new to ADesigner and there’s a colour problem stopping me.

Please have a look at this file. It’s been created with "Makemusic Finale".
This app does not work with colour profiles, so (as far as I know) there will be no profile included. The only colour used is 100k for strokes and fills.

Opening this file with my old Illustrator cs3 and saving it as an ai-file goes well. All elements stay at 100k.

But opening this file with AD all elements will be converted to 84-84-78-99 instead of 100k.
How can I prevent this conversion or convert everthing back to 100k?

I am thinking the file was originally set in RGB. When I look at the makeup in Acrobat DC the colour is not 100% K, but when opening it in Illustrator the colour is set 100% K but the document colour mode is set to RGB. This can make things confusing as you are seeing the CMYK makeup you want but the file is RGB and will give different results when placed in Indesign or viewing in Acrobat. 

Can you set Makemusic Finale to work in a CMYK colour space?

Unfortunately this app gives you no choice how to create export files. I only get this pdf as it is. 
(eps file is even worse ... they are not able to create an eps with embedded fonts. Illustrator can open eps without fonts as long as they are installed, AD not.)

The workaround by im/exporting with Publisher works fine, as I can see in Illu or Acrobat.
But opening it with AD afterwords turns everything again to rich black.

 

btw. In Illustrator I often use "Turn everything to greyscale" as a workaround. Is there anything similar in AD?

The app "Finale" does not give you any choice to control workspace nor export.
There are some hints that this app uses rgb, but I found no official statement.

But at least I found a new way: Printing to file (pdf or postscript) gives me a file, that (when opened and profile added in AD) has all blacks as 100k.

I’ll keep on trying, thanks.

Yes, the Acrobat way is similar to my preferred: the "Turn everything to grayscale" in Illustrator. And the manual conversion is not suitable working with hundreds of files ...  

So the "print to file" seems to be the best so far, even fonts stay editable.

I just want to get rid of all those Adobe Apps and work with Affinitiy, but there are still some very important features missing or buggy (esp. Publisher).
