(This is might be somewhat of a newbie question, but probably a little deeper than that...)
Here is a question/situation that I think should be easy to answer. Or rather...I hope is easy to answer.
Heres the situation... say I'm making an AU plugin with a simple generic view.
This plugin has several parameters...doesn't matter what they are/do/represent: gain, delay, whatever.
I want the the plugin to change the value of the parameter automatically based on any sort of condition, ***AND*** update the GUI to reflect this change. For example:
if (a != b)
{
mAudioUnit->SetParameter(kParam1, new_value);
}
This piece of code would (does) work great in the kernel process (just once a buffer, not every sample...I really don't need that). I can hear the change happening as expected by updating kParam1 to its new_value whenever a!=b. However, the slider bar does not move in the GUI. I really really want to see that happen. Its feedback to the user that shows them what is happening. How do I make that happen? Why doesn't SetParameter do it?
Ideally, the answer to this question is nearly as simple as the example code I posted, although I'm aware my expectations may be high.
Thanks for any and all help!
-Nick
