Buses row will now show the fill source again.

Key Buses row without changing the key source signal.
If you want to cancel the separation of key source and fill signal, press Key Bus.
Note: If you want to see in Split Key mode which source you have selected
as key source, press Couple/Split. The Key Buses row will indicate
the source as long as the button is held down.
