Use independent notes in the Score Editor in Logic Pro for Mac
When Enable Complete Features is selected in Logic Pro > Settings > Advanced, you can display notes in the score as independent notes and edit their independent status.
Independent notes are not tied to a rhythmic position in the staff, and can be moved freely. This can be used to add grace notes, for example, and for other purposes.

Do one of the following:
Choose Functions > Note Attributes > Independent from the Score Editor menu bar, then choose one of the following settings:
Independent Grace: The note is displayed as a single (independent) grace note.
Independent: The note is displayed independent of the rhythmic context.
Not Independent: The note is displayed in the regular rhythmic context.
Control-click a note head, choose Attributes > Independent from the shortcut menu, then choose an option from the submenu.
