The Modify button permits the selection of different modes for the treatment
of asynchronous sources in the switching levels (M/E1, M/E2, P/P):
On:
If Background/Program are asynchronous, enabled keyers are
disabled. If Background/Program are synchronous and the fill signal of a keyer
becomes asynchronous, the enabled keyer is disabled. If Background/Pro-
gram or Preset are asynchronous and a transition is selected, a cut is per-
formed at the end of the transition.
Off:
Asynchronous signals are phased over H and are passed.

KeyMemory AutoSave: On/Off
If the KeyMemo button is switched on in a Keyers menu, the key memory is
always recalled if the key sources are changed during control panel operation.
These changes can occur directly by selecting another key source or also indi-
rectly by changing the Fill source or the Split mode.
For storing the key settings in the key memory two modes are available:
1. Auto Save
If the switch Key Memory AutoSave=On, the settings of the previous key si-
gnal are stored automatically before the settings of the next key are recalled.
If the switch Key Memory AutoSave=Off, the stored settings of the new key
are recalled without saving the previous settings.
