Specifying microtonal accidentals does not work if note input is initiated with a note duration (hitting a number) and then selecting the accidental (clicking it in the accidentals side tab), placing the note in the score afterwards. It does work, though, when note input is initiated by clicking on a score position and using Enter. Perhaps this could be addressed so that all note input methods can be affected equally by the microtones. Thanks in advance.
First, create an 24-EDO atonal key signature (select 24-EDO and use the key signature popup to write atonal). Deselect everything. Now, hit a number to choose a duration… etc.
