I have successfully integrated cathedral chime which were over forty years old using one of these boards. All the sounds are in the board, so no actual chimes are necessary. This option is also popular with churches displaying inoperative cathedral chimes that may cost more to refurbish than they are willing to spend. They can retain the beauty of the real chimes without the expense of maintenance. Some of these boards sound very authentic, while others do not.
Advantages are space, expense, and maintenance.
A carillon usually has a keyboard console complete with pedal clavier, and is controlled by cables connected to the clappers. It is commonly interfaced with a clock to automatically toll the hour, and play a short tune. One of the very early automatic controllers , manufactured by Deagan, utilized a cylindrical metal drum with small metal lugs extending out from the drum, just like a music box movement. As the drum slowly rotated, the lugs passed over a row of switches connected to electric clapper solenoids to strike the individual bells, thus playing a tune. Please be aware that electronic carillons are not considered true carillons by some.
