276 KARRERA — User Manual
Section 7 — Advanced Operations
The ME and Pgm Pst data pads display the current partition control param-
eters for that element. On a new Karrera system the default settings assigns
the partition boundary to the partition level (PART).
Partition Boundary Control
The partition control information can be assigned to an E-MEM level, or not
be assigned (Not Assigned). Which level the partition control is associated
with controls the amount of isolation between Primary and Secondary par-
tition E-MEM behavior.
• For the Karrera default, the partition boundary is assigned to a different
E-MEM level entirely and complete independence of the split ME par-
titions results. This setting can be used to map all ME partition bound-
aries to the same separate level. This level can be used to preset the
partitioning of the entire switcher, and then Primary and Secondary
E-MEM operations would not change the switcher settings.
• If the partition boundary is assigned to the Secondary partition, recalls
by the Secondary partition splits that ME. This setting would work with
the shot clock example cited in the introduction, especially if the shot
clock is used frequently and the remaining resources of that ME are suf-
ficient. Note that there is a chicken and egg aspect to this mapping. The
ME cannot be split from the Control Panel by recalling a Secondary par-
tition unless the ME is already split. You will need to go to the ME Mode
menu and manually turn on Split mode to activate Secondary partition
recalls from the Control Panel. You will also need to manually turn Split
mode off from the menu to restore all the resources to the Primary par-
tition.
• If the partition boundary is assigned to the Primary partition E-MEM
level, every E-MEM recall of the Primary partition of a split ME
imposes the ME mode and the secondary resource assignments.
E-MEM recalls of the Secondary partition will not change the current
mode or alter any resource assignments. This mapping is useful in cases
where split ME mode is used occasionally during a show, but the ME is
normally used unsplit. Primary partition E-MEM recalls will split the
ME when desired and restores it when all resources are needed by the
Primary partition. Note that all the effects built on the Primary partition
will need to include consistent partition boundary information. If any
change is made later in ME partitioning, all the Primary partition effects
will need to be edited.
• If the partition boundary is unassigned (none), E-MEM recalls will not
affect the current ME settings. Changes can only be done manually in
the ME Mode menu.
A Primary partition is always associated with an ME’s main E-MEM level
and has a dedicated button in the Master E-MEM area (
ME 1 Pri
,
ME 2 Pri
,
Pgm Pst Pri
). A Secondary partition has its own level, enabled in Split Mode.
