ChurchBells - Version 2.1 Now your Desktop, Home, Church, Bank, Clubhouse or Civic Organization can afford its own Clock Bell Tower. A computer, amplifier speaker and this program makes a Bell Tower system that chimes the time playing Hymns and Carols on Harmonious Bells. Organization licenses are 140, which allow you to easily create and save your own custom chiming schedules. These are the only bell sounds I have heard where four part harmony is in tune.
