Key Chaining
Key Chaining allows you to chain keys to coordinate their keyer states (on
and off) on a single ME or from one ME to another. There are 15 Key Chains
available in a Karrera System. All keys in a chain transition on and off
together. Key Chaining is performed in the User Setup, Suite Prefs, Key
Chaining menu (
Figure 142 ).
Some uses for Key Chaining are:
• Keyers within an ME for language or Ident separations of clean feeds,
• Aspect ratio-specific graphics across more than one ME, or
• Advertising graphics on bus-linked MEs which already substitute
background pictures.
In the Key Chaining menu, you can configure which keyers are chained
together in each chain. The following rules apply:
• Each keyer may not be in more than one Key Chain.
• All keyers in a Key Chain will be equal in command priority.
Key Chaining is part of the Karrera configuration and saved as part of
File Ops, Suite Prefs. A layer of load granularity (
Key Chaining
button) has
been added to this menu.
Keyers are controlled from the Transition area on the Karrera Control
Panel. They can be cut on/off or transitioned on/off using the dedicated
Key Cut and Auto buttons. Key chaining allows for a single button push to
transition all the keys in the chain. A single keyer selection in the Next-
Transition area will similarly cause the other keys in the chain to be
selected. Then a single push of the
Auto
button or movement of the Lever
Arm will cause all of the keys in the chain to transition on one or more MEs
simultaneously.
Creating Chains
To create a Key Chain or chains in a single ME, simply touch a Chain
parameter data pad (Chain 1, Chain 2, etc., see
Figure 142 ) to select it (turns
blue), and touch the keys you wish to add to the chain. Touch another
Chain parameter data pad and repeat the process (for the same ME in this
case).
