Purpose - to impose the song structure onto the notation ready for playback and printing.
The song structure is entered directly onto the notation. It applies to all tracks simultaneously. Think of it as a transparency placed over your MIDI data to divide it into bars and sections. The song structure functions are accessed from the left-most icon on the toolbar. It consists of time signature, standard repeats and Double Bar (which causes the sequencer to stop). Music Master ensures that the normal rules of music navigation are obeyed, and will follow each of these markings as they are reached during playback. This means that you no longer have to have two versions of the song - one for printing and one for playing.
