On a different note you could if you want the some affect on all channels try injecting current into or pulling current out of the reference pin. I was going just to say putting a changing voltage on to the Ref pin, but you will be upsetting a potential divider so you will be sinking or sourcing current from the pin. you might get a few strange envelopes on the output signal. Too much time to sit at the keyboard, I better get back to editing videos. 🙂
interesting chip strange that if you want to send a attenuation level e.g. in the datasheet you can send it as 42 or 24 and you get 42 for both. Never sure if attenuation is like normal maths 🙂 Attenuation is a negative so saying -14dB attenuation is like - - 14dB which would be +14dB. the attenuation is 14dB in the same way you don't say the gain is +14dB as the word gain provides the '+' required. This is the same way i got a slapped wrist at Uni because I wrote "the delay was 10S" as seconds should be in lowercase as it's not named after a persons. Old Father Time don't count 🙂 i.e. W for power for Mr Watt, F for capacitance named in honour of Mr Faraday. Personally I blame the French as they put it all in to place with the "SI" units. 🙂 Looks like a useful chip to have in the back pocket.

Nice chip. Cool project!
