In order to use it (and have a correct playback, transpose, etc behavior), it’s probably a good idea to create a new tonality system that includes both the glyph and the chromatic interval.
U+E442 looks closer to the design of that slashed flat than U+E477.
Thank you all for the help. I think this is what I need, but I’m not finding a way to swap that glyph in. I tried following the directions in the link Marc Larcher posted, but I’m not finding instructions for how to actually swap that glyph in when I edit accidentals. Selecting “add glyph” — which would seem to be the obvious method — doesn’t do anything. Can someone point me in the right direction here? I’d also like to have it playback correctly, if possible. Thanks so much!
Marc’s link is really thorough in how to create a tonality system. After you created it, you still have to applied it (as any other key signature). Here’s the manual on that: Changing the tonality system
I did this in about a minute. Here it is step by step. In the key sig panel on the right:
- Switch to 24-EDO (Gould Arrows) and add a key signature in that system to your score
- Hit the pencil icon to edit that system
- Find the ÂĽ-flat (-1/24) symbol and double-click to edit it
- In the Edit Symbol dialog:
- Delete the existing symbol by clicking the bin icon
- For Range: choose AEU accis (U+E440–U+E44F)
- Double-click the ÂĽ-flat symbol with the slash to add it
- OK, and OK
Now you can assign the ÂĽ-flat to selected notes by clicking it in the panel.
