Many live PA artists try to combine the qualities of both traditional bands and dancefloor DJs, taking the live music element from bands, and the buildup and progression from song to song of DJs, as well as the sheer volume of music controlled by a single person (of a DJ as opposed to a band). By allowing the sequencer to handle the playing of basic musical data (as defined above), the live PA artist can focus on controlling what is most important to the listener: the actual musical quality of what is emanating from the speakers.
