Names of Churchbell playing devices I know played by churches

From the churches I've gone to, I've heard their beautiful bell music, and wanted to know the name of the church bell system they used to play their bells. Obviously, it's all electronic and pre-programmed and set to play at certain times. But at first, the earlier bell systems were giant tape decks towers that played giant cassette tapes containing the recording of the bell music . So this is just something I had learned and discovered and nocticed.  Mostly this interest is of myself, and upon hearing the bells, I can recognize the company by hearing it's music. So heaven forbid the  churches had silenced their bells, at least knowing  the bell system will continue to help rekindle my memories of the bell music that I once heard.
