I now have a Roon Server set up on a NUC. I’m using my laptop as a remote. Do changes I make via the Roon interface–identifying albums, fixing tracks, etc.–automatically propagate to the server? What about to other remotes?
All the data is stored in the central Roon database (on the NUC where you are running RoonServer) so it does not matter what interface is used to make the changes, these is only one copy of it.
Thus Roon and all the remotes reflect what is in the central Roon database.
