I just tried it again on my CVP-905:
When I activate the Piano Room, the fingering type and split point are set to the values last set in the Piano Room. So the piano room remembers the settings!
If I exit the piano room, the values are reset to the settings that applied before the piano room was activated.
However, the fingering type and the split point must not be locked. That's probably Whitecollin11's problem. As he writes, his fingering type and split point are blocked. If this is the case, the values of the Piano Room will be retained when you leave the Piano Room. Then no start registration helps because the fingering type and split point are locked!
By the way, the lock does not apply to the piano room; the settings last made in the piano room are always activated here.
