I created a transcription of a song in Dorico 6 which I left keyless (C assumed) that I am having a issue with. It continues to have instances of B# and E# and I have tried running Respell but I’m not entirly sure that I am doing it correctly because I have manually adjusted the part but as soon as I run respell they are back. My attempts to adjust it have in some case added double sharps too.
I believe you also can select a region (some bars), Ctrl+I (for Interval, I believe on mac it’s opt+I ?), then type B#=C. I suppose this also works for keyless…
Respell being the key term here, i.e. using one of the Respell commands. However, when changing notes in a part layout using the Shift+I popover like @koen1 describes, this will change the score as well (I just checked).
