I find it disappointing that these new doorbells do not supprt existing mechanical chimes like you have since your first release. I have a mechanical chime that plays the Westminister notes with 4 long brass tubes. I cherish this chime. It gives charm to the house as well. Now you must use a digital chime that is not pleasant to hear and also makes mechanical chimes useless. I hope you find a way to upgrade the doorbell so it continues to work with older home chimes. I may have to look elsewhere....
