Chapter 12 Tasks and Expressions 211
Starting from an Input Alternatively, you can trigger an auxiliary timeline using an external signal,
brought in as an input in the Input window. For details on how to configure
inputs see page 197. “Triggering Tasks” on page 203 describes how you use
an input to trigger a task. The task will be started when the value of the trig-
gering expression becomes non-zero. This expression may combine multiple
inputs and constants using operators (see “Expression” on page 212). For
example, to trigger a task when the input goes above 50%, enter an expression
such as this one:
ModWheel > 0.5
◆ NOTE: The task will be triggered only when the value of the expression goes
from being zero to being non-zero. In order to trigger the task again, the
value must first return to zero.
Starting from Another Timeline You can use a Control cue to position, start, stop or pause an auxiliary timeline
from another timeline. See “Controlling Other Timelines” on page 194.
◆ NOTE: You can not control the Main Timeline from an auxiliary timeline.
Only Control cues on the Main Timeline can control the Main Timeline.
To see the current value of an
expression, point at the expression
