Both the PRC, and TRC (and DKVBrowser, and any other participant) needs to be keenly aware that there are others involved.  A better protocol could have avoided a whole lot of the problems that this causes...but I suspect that the tablet and handheld teams over in Japan were in some sort of competition to see whose controller would ship with the piano, and didn't concern themselves with the fact that both might end up being available.  Anyway, I'm guessing, and this is all speculation.  Back to the point.

If it sticks, no one is arguing with you about the volume.  If the volume isn't appropriate for the level chosen, I would investigate other things as I mentioned in my prior post.

I'm wondering if it's being caused when you have more than one remote communicating with to your piano and a volume change on one remote does not successfully receive and execute notification of the change - creating an out of sync issue . And then the volume is adjusted it again on the other remote.
