Short passage with microtonal accidentals for one (section) instrument

[hautboisbaryton]

Hi folks, I’m trying to use the 24 EDO Stein-Zimmerman accidental for an 8-bar long passage in a work with an open key. The passage affects only four notes in the (divided) second violin staves.

Would anyone be able to show me how this is supposed to work? Every time I assign the tonality system and then attempt to assign the correct accidental, it just reverts back to 12 EDO and nothing happens.

How to keep my project keyless, but in 24-EDO tonality?

Hello! Want to implement quarter tones into my work for sax, but can’t set the tonality to 24-edo since I’ve started. Dorico seemingly MUST have a key signature in the 24-EDO tonality system in order to notate using quartertonal accidentals, but I don’t want that key signature in the score since there is a piano accompaniment (tacet in this particular section). Is it possible to reset the tonality system for the whole project without adding in a key signature? Or is there a way to hide that key…

quarter tone accidentals

So, I’ve created an Atonal key at the beginning of my piece. I click on the note I want to change, choose 24-EDO (it shows the quartertone accidentals). As soon as I click on one, it returns to 12-EDO and won’t give me the symbol. I’m jumping through hoops and I keep on landing where I started.

Thank you jesele!

Silly as it may seem, I had to put in a key signature to get it to work. I learned about Alt/Option clicking to assign to a single staff earlier today, and realized that I could do that within the Key Signature panel to make it for each staff only. Here’s the updated image with the signposts showing the changes:

Yes, that’s right. A tonality system in Dorico consists of an EDO setting, a set of accidentals and a key signature - which can seem a bit strange if you don’t actually want to change the key signature!

For future users with the same issue, here’s the steps I took:

1. Select note to be altered.
2. In the Key Signatures, Tonality Systems, and Accidental panel, select the appropriate tonality system.
3. Change the Key Signature to match the current key signature (in this case, I had an Open key signature, so I chose C Major) and then Alt/Option-Click the staff in the Key Signature section of the panel to have it apply to the current selection only.
4. Select the notes to change and then choose the new accidental(s) in the Accidentals section of the panel.
5. After the passage in question, you can return to the previous Key Signature/Tonality System by repeating these steps and changing your choices.
