Creating tune zones
By clicking the Tune button at the top of screen, you will be able to select different zone numbers, just like switch layer numbers. After selecting a number, place the zone tiles wherever you want (press space and select the light blue square). Next, you have to specify your tunes to each of the zone numbers. You can do this by bringing up the Server settings menu by clicking the button in the bottom right, and then typing in the Commands: field.
