That's what's confusing to me. In my child class, the graph property is defined as:

AUGraph graph;

In the parent class I have:

AUGraph pGraph;

@property (readonly) AUgraph pGraph;

and

@synthesize pGraph;

Then later in the parent Class implementation I have:

result = NewAUGraph(&pGraph);

and in the child class I try to do:

graph = [parentController pGraph];

Which is when I get that error mentioned previously. As you can see, I'm defining the property as an AUGraph, not an objective-c object.

AU graphs are not Objective-C objects, so you have apparently
misdeclared your property.
