It is a screenshot from the HDA Processor node's python module. I think the code that I highlight is for setting the HDA Processor node's parameter with the template_node's parameter.
But the parameter names in HDA Processor are all added by a prefix named "hdap_" actually, so the parameter's name in the HDA Processor will never equal to the original one.
As a result, I drop the hda node to the Template Node parameter of the HDA Processor node, the parameters do not initialize by the hda node.
