When enabled, the Double Bar option shows the final double bar line in the Score Editor window. The double bar line is located at the end of the last MIDI clip or event in the session. Enable the Double Bar option when you are ready to print the score.
When the Double Bar option is disabled, there will be a number of empty bars at the end of the last MIDI clip in the session. The number of empty bars is determined by the Additional Empty Bars In The Score Editor setting in the Pro Tools MIDI Preferences (Setup > Preferences). Disable the Double Bar option to manually enter notes in the Score Editor after the last MIDI clip.
