MIDI : Score Editor : Score Editor Window Menu : Scrolling

Scrolling
The Scrolling submenu lets you select the scrolling options for the Score Editor window independently of the Edit window and any MIDI Editor windows. The scrolling options include:
No Scrolling
The Score Editor window does not scroll during or after playback. The playback cursor moves across the Edit window, indicating the playback location.
After Playback
The playback cursor moves across the Score Editor window, indicating the playback location. When playback has stopped, the Score Editor window scrolls to the final playback location.
Page
The playback cursor moves across the Score Editor window, indicating the playback location. When the right edge of the current page shown in the Score Editor window is reached, it scrolls to the next page and the playback cursor continues moving from the left edge of the window.
Follow Edit Window
When selected, the Score Editor window follows the scrolling option selected for the Edit window (Options > Edit Window Scrolling).
*
For Pro Tools HD systems, the Continuous and Center Playhead scrolling options are not available in the Score Editor window. If the Score Editor window is set to the Follow Edit Window scrolling option and the Edit window is set to either the Continuous or Center Playhead scrolling options, the Score Editor window scrolls by page.
