Tool : SetInput

Sets the value of an Input at a given time, with a number, string or other Parameter object.

The time argument may be omitted, if the input is not animated.

A similar result may be obtained by simply indexing the input with the desired time, and assigning to that.

SetInput(string inputID, (number|string|Parameter) value [, number time]]))

inputID: the ID of the input to be set
value: Can be a number, a string, or a Parameter, depending on the DataType of the Input.
time: the keyframe time to be set (optional)
