Assign the the track output to the stereo output you are using for all the tracks (For Example; Built-in Line Output 1-2)
Assign the input to a mono bus that is not being used. Choose New Mono Bundle then a new bus (Bus 3 for example).
Insert a reverb on the aux track inserts. If the reverb mas a Mix setting, set it to 100%.
