Key Bus
The Key Bus is the M/E's top layer, which is used to select sources that can be
keyed over the BG and PST buses. Please note:
~
Except for SHIFT, all buttons on the Key Bus are mutually exclusive.
~
On the M/E, the Key Bus is shared between KEY 1, KEY 2 and Custom
Control functions. The SEL button chooses the active function, as
indicated by the LEDs to the right of the bus. Refer to the
Section" heading on page 71 for details.
~
If a key is on, you can "hot cut" key sources on the bus, provided that the
bus is selected (using SEL).
Background Bus
The Background Bus (BG) is used to select the M/E's bottom layer — the image
that is visually behind the M/E's two keyers. Please note:

Except for SHIFT, all buttons on BG are mutually exclusive.
Preset Bus
The Preset Bus (PST) is used to select the M/E's next background. Please note:

Except for SHIFT, all buttons on PST are mutually exclusive.

When a PST source is taken to Program, the source "flips" to PGM. In
Chapter 7, refer to the
page 269 for details.
Refer to the "M/E Transition
about transition combinations.
Key Control Section
The Key Bus is a shared bus. The SEL button toggles the bus between KEY 1,
KEY 2 and Custom Control functions. The three LEDs indicate the active
function.

When KEY 1 or KEY 2 is selected, Key sources can be selected and
adjusted for the indicated keyer.

When Custom Control is selected, the entire row of programmable
displays changes to show the custom control functions that have been
mapped to the associated buttons. In this mode, pressing a button on
the Key Bus executes the assigned function.
Note Custom control functionality on the Key Bus is not available
