Insert Silence Between Locators (Global) ⌃⌘Z
Inserts “empty space” between the locators. Allows you to easily create gaps in a project so you can add new regions (MIDI or audio).
Alternatively, you may want to insert some empty bars in the middle of a project, to create space for another chorus, verse, or bridge, for example. As with the previous example, all existing tempo changes and so on are moved accordingly (to the right by the number of inserted bars).
