Does the programmer actually schedule the music into the system or does the programmer just set up rotations to play continuously? In other words, I have a station with 3 rotations, one with 8 songs, one with 11 songs, and one with 14 songs. Does the PD just tell the automation to play song 1 from rotation 1, song 1 from rotation 2, song 1 from rotation 3, song 2 from rotation 1 and so on or do they actually have to schedule it by hand?
