Settings for Key Auto Drop Function
The “key auto drop” function automatically switches off a particular key when
you press a cross-point button in a bus that outputs the background on the
particular switcher bank (PGM/PST, or M/E-1 to M/E-3).
When the background output bus is in flip-flop mode, this is always the A bus.
In bus-fixed mode, it is either the A bus or the B bus depending on the fader
lever position.
For details of bus-fixed mode, see “Executing a Transition” in Chapter 3
(Volume 1).
