Hi,
Is it possible to obtain JSON data stored in the “data” data field using some method and not by the callback “dataFromJson”. I need specific JSON data at the time when the plugins module ctor is called.
“dataFromJson” seems to be called by Rack in unclear intervals. Sometimes when a new plugin instance is created, it is called, sometimes not. Is there a rule, when it is called?
Thx, rma
What’s limiting you from using the dataFromJson to initialise the objects you would create in the ctor ?
ctor is called before dataFromJson is called by Rack or do I misunderstand that?
I initialize process data in the ctor, thus I need all data from the json at construction time.
yes, of course, constructor is called before, and immediately after is called the “fromJson”
I don’t understand why you can’t init or change the status to your members in the “fromJson”
of course “dataFromJson” will be called only for modules coming from open file - cut&paste - undo&redo actions
Blockquote immediately after is called the “fromJson”
I wasn’t aware it is always called immediately after, will implement a “delayed” init of the params then.
Thanks also for the hint on when dataFromJson is called otherwise 
Your MyModule() constructor should initialize your module in its default state. When dataFromJson() is called, its state should be replaced by the given JSON.
It is called if creating a module with a template preset, cloning a module, loading a patch, etc.
