Parameter Data Default Item
The parameter data default item atom contains the default value for the parameter. This value is stored in a QTAtom and can be copied directly into the parameter or into an effect description; an application does not need to understand the contents or format of the atom in order to do this.
The parameter data default item atom is required, except for group descriptions.
