Selecting/repitching All notes of the same pitch (class)

Hi,

Is it possible to select all notes from the same pitch class ( say, …,C-2,C-1,C0, C1, C2, C3 …) repitch all pitches by a quarter-tone, say flat?

By repitching I mean accidentals. Say, I want to change all B-flats to B-quater-tone-flats.
I have already set my 24-EDO accidental.

Any help would be greatly appreciated.

You can use Edit > Filter > Notes by Pitch to select all notes of a given scale degree; once they’re all selected you should be able to apply the desired accidental from the panel.

Thank you, Daniel.
