I'm a little stuck with audio units and parameter handling. I'm using
a different UI than the ones in the examples (I'm using VSTGUI), and
I don't really know how to properly implement event handling.
- There are 2 Get/SetParameter functions (one in AUElement, one in
AUBase). Which ones do I call for what purpose? Do I need to override
any of those functions and if so, why?
- I understand, that presets use the AUElement Get/SetParameters for
loading/saving presets. When a preset gets restored, how do I notify
the UI of that?
- in most of the examples, there are GetParameter calls in the
Process function, which strikes me as inefficient, as soon as you
have a lot of parameters, or few parameters that would calculate
coefficients. Is there a more elegant way of notifying the effect,
that parameters have changed (through automation or preset setting) ?
Thanks in advance for answers.
Peter
