Regenerate a Session Player performance in Logic Pro for Mac
You can regenerate a Session Player region to quickly create a variation of a performance without editing any of the settings in the Session Player Editor. Regenerating a performance is more noticeable when you’re using more complex styles or when you’ve increased settings such as complexity and fills.
Regenerate the performance
In Logic Pro do one of the following:
In the Session Player Editor, click the Regenerate button, located below the Session Player button.
In the Tracks area, Control-click the Session Player region, then choose Edit > Regenerate from the shortcut menu.
