A new client has moved into an apartment that belonged to one of our longtime clients who has since traded up to a townhouse. The new client wants to ring the doorbell through the room speakers via the PAD8. The email below came up when I searched the group for comments on deploying this feature.
Is it really worth 'ramping' the value between the current source volume and the doorbell volume? I'm not convinced this is necessary or beneficial.
I plan to use a MC3 to play the MP3 doorbell files. Is unity gain for the audio out ~80% as it is for the PAD8?
TIA

Im sure many others have probably written their own code or module to do this. I created one that goes between the bipad or swamp, tracks if the room is currently ON,what input on the audio switcher, what the current volume is. It has parameters where you set which input on the switcher is your doorbell source, how long the doorbell should play, what volume the doorbell should play and what duration to use for ramping the volume up&down when the switcher goes between original source and doorbell.
So basically it just remembers what you were doing if the room was already on. Inside the module were DRAM and ARAM symbols, analog inits, presets and rate limiter. A stepper used the parameters and did the following:
Doorbell pressed:
Store current room settings
Ramp Volume Down
Turn the Zone on the switcher
Switch to doorbell input
set doorbell volume
play dooorbell wav
Cut doorbell volume
recall previous room state
If room was originally off, turn it off again.
Recall previous source (if there was one)
Recall previous volume
It works on the couple jobs I used it, I feel like given more time I could have improved it more but whatever.
