Howard,

Your effect base can implement GetProperty() and fill in data for your internal needs. You get back a void* data which is sufficient for about anything...

You can use a timer driven control (see my framework's idle() function for control objects :-) in the GUI to retrieve data from the dsp vie calling the AudioUnit's GetProperty()...

Note that Apple wants properties 0-63999 for themselves, so you can start at 64000...

Cheers,

;) Urs

How can the AudioUnit view class and effects class communicate, other than via bound controls? Suppose I want my view class to display the graph being generated, or for the effects class to be changed by some user action that is not on a bound control? At the moment, I have a pair of global variables, but that's not a good solution. Is there a member variable or function somewhere in the base classes that will allow me to have one notify the other in situations like these? Thanks...
