NAUTILUS DJ is a complex music scheduling system for radio stations; capable of handling not only your musics, but also your Jingle sets, IDs, and even your NEWS and commercial inserts. Your songs can be assigned into categories, your categories can be sorted into groups of songs called folders. Each song can be assigned to as many folders as necessary.Since 1994 we have developed the music scheduler with close connection of many different radio stations. To suit the needs our rule system contains rotational, and rule based scheduling, and not only for the musics, but for the jingles too. The songs, and jingles can be organized into folders, list, and you can apply rules within these folders. The freely definable packet sizes amongst the categories can help the entry level music director, and could be a very powerful tool in the hands of a pro. You can define as many clocks, and weekly grids as required for your day by day scheduling. The software works perfectly with its radio automation part called NAUTILUS JUKEBOX.
