KARRERA — User Manual 233
E-MEM & Timeline Operation
Running the effect departs from the normal state to do whatever is
required. When the effect comes to the end of its run, the next to last key-
frame controls the transition that occurs at the end of the effect. The last
keyframe has no following keyframe and so does not transition, and that
keyframe effectively has no duration. You can set the next transition ele-
ments in this last keyframe to the normal state without fear of causing
unanticipated transitions. This return to normal technique permits com-
pletely controllable seamless shifts between your effect recalls and runs
and your live switching.
When building effects for the show, take care that the beginning and ending
of every effect works well with the normal state. You also may wish to
apply a Source Hold to the first keyframe to ensure the last source selected
remains unchanged going into the effect.
Source Holds in Effects
During E-MEM recalls and effect runs sources can be programmed to
change. Sometimes this is not desired, as an effect may be designed to run
on the currently selected sources, not the particular sources used when the
effect was built. Holds can be programmed into an effect with the Source
Holds menu to prevent sources from changing when that effect is recalled.
This form of hold is keyframeable, and so can be applied to specific por-
tions of an effect.
To Set a Source Hold in a New Effect
1. Go to the Source Holds menu (
E-MEM & Timeline
,
Source Holds
).
2. Select the buses you wish to hold by touching their labeled buttons on
the menu so their green indicators illuminate (
Figure 117 ).
