Logic pro not validating plugin due to Meta parameter

AU Plugin in Logic Pro failed in validation with the following message:

“Parameter values are different since last set - probable cause: a Meta Param flag is NOT set
on a parameter that will change values of other parameters.”

Is everybody knows about Meta param something?

MacOS Big Sur
Logic Pro 10.7.3
AU Plugin

It’s not due to meta parameter but it says you might have a meta parameter as it sets a param
but when it read back the value, the value has been changed.
So you either have a parameter that modify another parameter or just this parameter do not retain its value correctly.

I have this error

Given the numerous error, it seems just that your parameters do not retain their value.

How to determine which one parameter doesn’t work? Name?

you can put some print in your get/set method

I find it easiest to use pluginval to debug validation issues.

I wrote up some tips on using pluginval here.
