The TweenValue identifier represents the tween track itself. To control the 
parameter using an input, simply enter the name of the input instead.
Triggering Tasks You can use an input to start an auxiliary timeline by entering the name of the 
input in the Trigger column of the Task window.
Press Enter to complete the formula. The task will be started whenever the value 
of the formula entered in the Trigger column becomes non-zero. You can 
create more elaborate starting conditions by entering a more complex formula 
including multiple inputs, numeric constants and operators. See “Expression” 
on page 212 for more details.
Enter the name of an input to 
control the parameter using that 
input. This example uses a MIDI 
controller, as shown on 
page 198. Or enter a formula 
combining inputs, numerical 
constants, operators and the 
original TweenValue. See 
“Expression” on page 212 for 
more details.
Click in the Trigger column of a 
task to enter its starting condition.
A red border around the 
field indicates an error in 
the formula.
