MIDI : MIDI Editors : MIDI Editor Window Toolbar : Grid and Nudge Selectors

Grid and Nudge Selectors
When the Expanded Grid/Nudge Display option is enabled in the MIDI Editor Window menu, the Grid and Nudge selectors in MIDI Editor windows function exactly the same way for MIDI data in MIDI Editor windows as in the Edit window.
When the Expanded Grid/Nudge Display option is disabled in the MIDI Editor Window menu, you can toggle between Grid Display and Nudge Display using the Grid/Nudge Display selector.
