• running a particular command,
• running a preset, or
• mapping the value of the source parameter to a destination parameter.
Running a command allows the event to directly execute a single command to
change a SoundStructure parameter via a valid API command. An example is
muting all microphones as the action for when a button is pressed.
Running a preset allows the event to execute either a partial or full preset. An
example of this type of action is changing the room matrix routing when a
button is pressed.
When the Always trigger is used, it is convenient to use the Map action. The
map action allows the value of the destination parameter to track the value of
the source parameter with a single event. Both Boolean parameters (with
values of only 0 or 1, e.g., mute state) and numeric parameters (with values
from a min to a max value, e.g., fader value) may be mapped.
Action maps may also be inverted to allow for the case where it is desired for
the destination parameter map to be the inverse of the source parameter. An
example of mapping Boolean parameters is shown in the following figure with
both a direct mapping (true ◊ true) and an inverted mapping (true ◊ false)

False
An example of mapping a Boolean parameter would be tying the mute state of
a microphone to the logic output state that drives an LED. Changes in the
mute state of a microphone would be mapped directly to a logic output pin.
Numeric parameters can also be used in action maps. An example of mapping
a numeric parameter is mapping the analog voltage from the logic inputs to the
fader of a particular channel. In the example shown in the following figure
(left), the values from the volume knob are mapped to a fader. The analog volt-
