Configuring the Sound Cue Editor
Double-click on Vivaldi_Spring_Allegro_ByJohnHarrison_Cue to open the Sound Cue Editor. Notice that on the right-hand side, there is Palette with a list of nodes, as shown in the following screenshot. These nodes can be used to control how the sounds are played or heard.
If you find that your sound design cannot be achieved using the nodes in the list, you can alternatively request for new nodes to be created via the UE4 source code.
