In Harmony, you can use expressions to automate the calculation of effect values based on the values in another function. An expression is a mathematical formula that allows you to manipulate the value in the source function to create new values for the destination effect.
The Expression dialog box is where you write expressions. It's a simple text editor that can handle incomplete or invalid JS programs although they will not be evaluated. Harmony can save and load invalid JS programs.
The Expression editor evaluates the current script at the current global frame and reports any errors or returns the numerical result of the program.
For tasks related to this dialog box, see About Expression Columns.
