A college classmate of mine was born blind, but has been working in radio in New Brunswick for just over 20 years now, primarily at Moncton's country outlet, Stingray's CJXL-FM "New Country 96.9". He's the music director and one of the jocks, and is a wizard with MusicMaster, using a screen reader like JAWS to "see" what's on the monitor. He's able to do live on-air shifts on his own, as he programs, in MM, "pause" points on the automation playlist, then simply hits a button on the console to start what's next on the playlist.
