I feel the feature that helps me the most and saves me the most time is the ability to design assignment grids for the different events during the year and activate them when I need them such as Christmas music. I set up my clocks the way I want them and then build a grid and activate it and I am all set. Just build a grid around whatever activity you are doing and that's all there is to it.
We chose MusicMaster because we had heard it would fill our needs and it has. So word of mouth and affordability helped us make our decision.
