I see that sometimes (I haven’t figured out when) ProTools records parameter changes in its Undo History. Sometimes it doesn’t.
Are there any rules to it? What could cause PT not to record parameter changes in its Undo History? Anything my parameter class is missing to have PT always record changes in its Undo History?
I am not sure yet, but it seems that changes from the GUI are generally not recorded, while changes from an external control module sometimes do get recorded.
Any hint, or idea what to look for is highly appreciated!
