Section 3 — Switcher Concepts
When ENABLES is selected in the Timeline Menu, all enabled
levels are also delegated; thus all enabled levels are affected by
changes made on the control panel. When a level is not enabled,
its timeline does not appear in the Timeline Menu.
■ In ENABLES mode, pressing the Enable button toggles the
E–MEM enabled status of that level or channel either on or off.
This does not change the status of any other enabled levels or
channels. Enables and delegates are tied together in this
mode. If a channel is enabled for E–MEM functions, it is also
delegated for Keyframe-editing.
When DELEGATES is selected, only specified enabled levels are
delegated; all other enabled levels are enabled but not delegated.
The timelines of all enabled levels are displayed in the Timeline
Menu and the names of the delegated levels are highlighted. This
feature allows you to edit a delegated timeline while viewing its
relationship to enabled timelines not being edited.
■ In DELEGATES mode, pressing the Enable button of a level or
channel that is not enabled toggles it to an enabled and
delegated status. This does not change the status of any other
enabled levels or channels. Subsequent presses of that
enabled button toggles the delegation of that channel on or
off. If you wish to toggle the enable status off, you must leave
the
DELEGATES mode and go into the ENABLES mode.
Enables and Delegates Button Tallies
The E–MEM Enable buttons have three tally levels:
■ High tally — the E–MEM is enabled and delegated for
Keyframe-editing
■ Low tally — the E–MEM is enabled but not delegated
■ Tally off — the E–MEM is not enabled and not delegated
Refer to the E-MEM control panel description in the Operation
Reference manual for a detailed description of the functions
controlled by each Enable button. Refer to Appendix B—Keyframe
Facts, for further information on enabling and delegating E-MEM
levels.
