You shouldn't be making this assessment when you are rendering. There must be some condition that is being met (or can be assessed) that would trigger you to change the parameter display info, so you should do that work and notification at that point.

First off, please disregard my last email, I have since solved that issue.

Now here is my question:
In my AU's Render method, I call
PropertyChanged(kAudioUnitProperty_ParameterInfo...)
when it detects that a certain Parameter has been changed that affects the
appearance of other parameters.
(if the parameter should be shown, I return noErr from GetParameterInfo,
and if it should be hidden, I return kAudioUnitErr_InvalidParameter)


Now this works fine on an AULab input channel, but I've found that it
doesn't work on an AULab output or in any channels in Logic.

Any suggestions on how this should be done differently so the
ParameterInfo always gets updated as neccesary?
I suspect because Render is not being called, but I'm not sure...

Thanks,

-Kevin
