Not entirely sure what you are looking for. You can have multiple shows and schedule different times for each different show, just think of it as a Outlook Calendar with appointments. Your shows can be made up of just music if you want. Also, you can make a media sequence, without effects, and have it run windows commands during the sequence. Just right click on the wave form in the top of the sequencer and click show media clips. Then right click again in the media clip section and click insert Windows Command. You can of course use this with effects also, but I am assuming you want it to do something during the day.
