This custom action doubles the length of a selected area of a project on all tracks. It can be useful for adding an extra chorus for stretching out an instrumental chorus for a soloist. To use this, select the area of the project to be doubled, then run the action with alt control shift V. The action will leave you at the end of the selection, ripple will be set to all tracks, and the selected track will be the first track in the project. Back up a bar or so to hear the result of the paste.
