Audio Unit (debug) output parameters

Hello all,

Besides my recently posted MIDI message I wanted to ask if there is a generic way to create read only "debug output" parameters in an Audio Unit to let the user see what is going on, let me elaborate.

The Apple provided "Dynamics Processor" AU has a "comp amount" meter in it which updates as the input signal is processed. This is a great way of providing some feedback to the user and I'd like to add a similar meter to one of my new Audio Units.

Is it possible to create such a meter without implementing a custom Carbon or Cocoa view? Which parameter type or flags should I use for this? If someone has a pointer to some documentation or sample code, that would be awesome. Thanks in advance for your time.

With kind regards,

Frank Schoep
