Switches
The Automation deals with switches differently to Faders, since only transitions
(from On to Off and vice versa) are recorded by the automation: instantaneous values
for the duration of the Mix are not recorded. This has implications when you want
to edit switch settings within the Mix.
The top trace in the diagram below shows, by way of an example, the setting of a
Cut switch as the Mix proceeds. Suppose that you wanted to make some adjustments
to the time that the Cut switch is operated. In the diagram two changes are made, in
both cases the dotted line show the original transitions, and the solid line shows the
new transitions.
The first change is easier to make for the reason that you are moving the event
forward in time (i.e. earlier). Because of this you can put the switch into Armed
mode at some time before the change is to be made and at the appropriate time press
the Cut switch. Because it is still in Armed mode after the new event it will follow
the next recorded event, i.e. the transition from On to Off.
The second change is more difficult because you are moving the event backwards
in time (i.e. later). If the switch were to remain in Armed mode the old transition
would still be replayed, all you could do would be to quickly turn it off again. The
way to deal with this correctly is to put the switch into Write mode at some time
before the required change (see diagram). The Automation will then overwrite the
existing transitions with the transitions from the switch. You may then make the
new transition at whatever time you wish. If there are more transitions which you
want to keep you must put the switch back into Armed Mode, or Read mode, as
soon as you have made the change.
As was explained in an earlier section, the selected Switches may not be put into
different modes independently of each other. The selected switches (on a particular
input strip) will all be in the same mode as each other, i.e. the mode which the LEDs
are displaying. The non-selected switches will be in Read or Armed mode. It is
therefore essential, when putting a switch into Write mode, that it is the only selected
Switch on the input strip. Failure to do this will mean that you overwrite switch
transitions on other switches.
