Selecting a Function

The pop-up menu at the bottom of the Transformer is where you select the function, that is, the basic type of editing to be performed.
Delete

Removes or mutes all found elements from the output stream. The actual elements on the track are not affected.

Transform

Changes one or several aspects of the found elements. You set up exactly what is changed in the action list.

Insert

Creates new elements and inserts these into the output stream. The new elements will be based on the elements found by the filter conditions, but with any changes you have set up in the action list applied.

Another way of expressing this is that the Insert function copies the found elements, transforms them according to the action list and inserts the transformed copies among the existing elements.

Insert Exclusive

Transforms the found elements according to the action list. All elements that do not meet the filter conditions are removed from the output stream.
