You can use blend containers to create complex and realistic soundscapes, so you will probably want to test them as you go along. By using the Transport Control and the Blend Track Editor, you can audition the contents of a blend container. You can then make adjustments on the fly, such as resizing crossfades or adding RTPC curve points.
In the Blend Track Editor, a cursor is provided so that you can change the game parameters while you are playing back the blend container. Since you have already mapped these objects to Wwise property values, when you change the game parameter values, you automatically change the object property values. This simulates what happens in game when the game parameters change so you can verify how effectively your property mappings will work in game.
