Key Bus Key Bus (on the right) directly selects the key and fill sources on the key bus.
When the key is lit, the key bus indicates the source which can be used for keying
and filling.
Couple/Split Couple/Split derives the key source from a different signal than that of the key bus.
When the key is lit, the coupled key source signal is selected in addition to the se-
lected key fill signal. Without coupling, the key fill signal corresponds to the key
source signal (self key).
For selecting any key source, proceed as follows:

Now select on the key bus the new key source.

After releasing the keys, the state is shown by the Split Key display. The key
bus indicates again the fill source.
The key source signal is now determined. The key fill signal can be switched with
the key bus.
If separation of key source and fill signal has to be cancelled, just press Key Bus.
Note: If you want to see in the split key mode which source you have selected
as a key source, press the Couple/Split key. The key bus indicates the
source as long as the key is pressed.
