Basic E-MEM Operations
The following topics describe enabling register effects, storing and
recalling effects, Effects Dissolve transitions, and Learn Sequence
operations.
Enabling E-MEM Register Levels
The E-MEM Enable buttons are used to set up switcher functions
which may then be learned or recalled from an E-MEM register.
Each register is partitioned into sections (or “levels”) based on the
state of the Enable buttons.
If AUTO RCL (Auto Recall) is on while an effect is learned, the state
of the Enable buttons is learned as part of the effect. Turn AUTO
RCL off to not learn the enables for an effect.
Refer to your Operator’s Reference , Control Panel Descriptions,
Effects Memory Subpanel, for more information.
