Song View is where you can arrange Scenes into a song structure. Open Song View by clicking the tab to the right of the Library area. Start building your song by dragging and dropping Scenes from the Scene Player into the Scenes Track.
A waveform overview of your song will render in real-time in the Master Track during playback.
To the left of the Master Track, there is a Track Sidebar tab labelled 'Master' - clicking this will take you to the Master View. Use the Track Sidebar tabs to navigate between the Song and Master Views.
