Saving your work
We recommend that you save your work regularly while carrying out the procedures
included in this chapter. Not only is this good practise during normal operation, but in
this instance it may save you from losing some set-ups that could prove useful later on.
To do this, create a new show (see “To open the Automation screen” on page 112), and
then continue reading through the remainder of this section, following the instructions
carefully. Save your work at convenient points (see “To create a new scene using the
current settings” on page 115 and “To save a show or create a new one from the
current settings” on page 113).
Saving a show versus storing a scene
It is important to understand the differences between saving a show and storing a
scene.
• Storing a scene saves the current settings of the system to the show file. Scene
data is never updated unless you manually store a scene. The show file remains
unsaved in RAM.
Although the state of the control centre is copied every five seconds, it is not stored
in a scene. Instead, it is placed in the NVRAM (non-volatile random access memory)
of the control centre’s memory, which is a type of RAM that doesn't lose its data
when the power goes off. If the control centre loses power accidentally, these
settings are loaded so that audio parameters are identical, thus avoiding audio level
jumps. When power is lost, the showfile loaded (if any) will not
subsequently be restored, and any unsaved changes to it will be lost.
• Saving a show copies the show file onto the internal solid-state disk of the control
centre. This provides you with a ‘permanent’ copy, provided you shut down the
system properly as detailed in the following section.
Shutting down the control centre properly
When switching off the control centre, we recommend that you use the shutdown
option of the GUI menu (see “To switch off the control centre” on page 43).
By using shutdown, the cached copy of the show data, which is maintained by the
system, is automatically stored. Shutdown then uses the current showfile, NVRAM data
and cache files to restore the control centre to exactly the same state as at power
down; even to the point of loading the unsaved show and placing you at the correct
scene, with non-stored scene data at the control surface.
If you don’t use the Shutdown option the audio parameters are still restored, but the
show and show status (saved/unsaved) cannot be restored automatically. You must
manually reload the show, and any unsaved changes will be lost.
