Saving and Loading Expressions

You can save the current contents of the expression editing pane as a file then load it back later on other parameters. Expressions are saved as plain text files with an extension of .expr2. By default, they are saved in the Expressions folder of the current project.

As well, you can save and load expression presets.

NoteExpressions are not validated when saving — the contents of the editing pane are written as is to file. Similarly, expressions are not validated when opening — the contents of the editing pane are replaced with the contents of the .expr2 file.
