Force Interpretation    ⌃⇧I

You can change notation to “look right” but force a desired interpretation.

One example is that if a note has the length of an eighth note, and the score shows an eighth note plus an eighth rest — forcing interpretation will change the note displayed as a quarter note, but continue to play it as an eighth note.

Logic Pro part box overview — Apple Support

When Show Advanced Tools is selected in the Advanced preferences pane, you can add notes and other symbols from the Part box in the inspector. The Part box contains a complete collection of score symbols, arranged in groups. You can control which symbols are displayed in the Part box, reorder symbol groups, and open the Part box as a separate, floating window.

  Independent Grace

Makes a note on the score an independent grace note. When scoring music we don’t worry about the actual performance — that’s the job of the musician. When an automaton interprets a score it needs to know the rules for performance.

Make the rules clear so the music can playback in the expected manner.

Independent Grace: The note is displayed as a single (independent) grace note.
