Song View is where you can arrange Scenes and Audio tracks 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.

The small arrows in the divider between the Song View and Scene Player / Deck area allow you to collapse or expand both parts of the user interface. This is particularly useful for projects with large amounts of tracks.
Use the Track Sidebar tabs to navigate between the Song View and Master View.
