Yes, the two keys in question are a black and white key adjacent. I'll pull things down and look to see if there is any obstruction, then regulate the action on the keys. I just wanted to know I wasn't on a fool's errand before I took a half day doing that.While the DC3 Pro is it's own beast, I think it's mostly a Mark III variant with higher resolution sensors and servos. It uses the DKC500RW controller and was built in 2000.

Subject: Re: [disklavier] DC3 Pro Key Sensor QuestionI could be something fell between the keys. Are those two keys next to each
other? It could also be a piano action problem. Is this a MarkIII model?
I doubt the sensors need to be replaced. First, look for a foreign object,
then check the action regulation. Then the key sensors can br adjusted in
maintenance mode, and that may require a technician.

It really sounds like a very small object has
lodged between the keys. In my experience, objects have been as large as a
coin, or small as a large grain us sugar from a cookie. Sometimes a seed
from a flower, or a pine needle or leaf. Also check to see that the piano
hammers are not touching each other when the notes are played. I use a
thin palette knife to swipe between the keys. Just be careful.
Once it was some baby mice!
