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.”
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.
