4.3.2 Playback of selective memories

Recalling selective memories works the same way as recalling standard
memories, but there are some advantages on programming selectively
Free combination of a number of selective memories:
Saving storage capacity:
Drawback of selective programming:
A memory, setting the position of the scans can join
together with pure color memories or pure gobo
memories. The same color memory may be recalled
during a running chase for movement. Operating in
this way saves time when programming up and saves
storage capacity.
On a selective memory, only the data of the selected
channels get saved. Using selective memories
enlarges the number of chaser steps possible to
program later on.
Using selective programs requires a good overview of
the stored programs. As selective memories affect
only selected channels, the picture they produce on
stage may be different depending on the picture
before.
Example: If the beams are doing a circle and a new
memory only contains a new pan/tilt position, push-
ing this memory will only move the centre of the
circle to the new position but will not stop the circle
movement. To stop the circle and to send the scans
to a new and well defined position, the new memory
needs to contain the information "Set radius to 00"
and CIRCLE has to be selected in its STORE MATRIX
for all the scans.
To avoid confusion on using selective memories, the
memories S1 to S10 should be programmed to contain
some standard memories with fully selected STORE
MATRIX.
In addition there should be some "Stop" memories
like "Circle Off", which only set the circle radius to 0
for all the scans, or "Shutter Strobe Off".
