How to save string in effect property

[baconssu]

Hi, I want to save a string value in each effect, and this param will keep its old value when AE restart.
I have tried PF_SliderDef "value_str" property, it lost old value in next app launch.
It is there any way to do it? If i can save a custom model in project file will be great!
Thanks for your help.

your options are to either use an arb param (hidden or visible), or sequence data.

with an arb param the user can undo/redu changes, but hitting the "reset" button will force the param back to it's default value.

with sequence data, there's no undo/redo, but the data survives a reset.
