I use original Panther SDK, I've compared the AUBase.cpp with the
latest SDK and they are identical in DispatchGet/SetProperty for:
case kAudioUnitProperty_PresentPreset:
case kAudioUnitProperty_CurrentPreset:
I use dynamically generated list - CFArray with callbacks for retaining
and releasing AUPresets.
Any suggestions?
Thanks

It does, and the SampleEffect Unit that provides factory presets passes
validation without warnings.
then what should I do? My Save/Restore calls the AUBase methods and
adds/takes new properties (vstdata).
The problem is that the name set when setting either of these
properties:
case kAudioUnitProperty_PresentPreset:
case kAudioUnitProperty_CurrentPreset:
Is not being saved. In the latest releases of the SDK I can see in the
SetProperty implementation in AUBase how these two are being handled
correctly...
What version of the Apple - CoreAudio SDK are you based on?

And this is how I handle preset changes:
OSStatus LPAUSynth::NewFactoryPresetSet(const AUPreset& sPreset)
{
VST_PLUGIN_CLASS::setProgram(sPreset.presetNumber);
SetAFactoryPresetAsCurrent(sPreset);
return noErr;
}
Strange thing is, I receive this Warning, even if I don't provide
Factory_Presets property.
Thanks for advice

You are looking in the wrong place I think....
The preset name is SET by another property "PresentPreset" into a
member variable of AUBase that then the Save (and Restore) code in
AUBase appropriately gets and sets...
AUPreset mCurrentPreset;

I also see this warning in our plugins. I've tried to add presetname
string manually - completely override SaveState/RestoreState - and
retain CFString for sure and also let the base classes do the thing,
but I still see this warning. I use original Panther CoreAudio SDK.

The Current (or Present) Preset property is called to set the name
of
a
preset. Then the preset (ClassInfo) is retrieved and the name is
expected to have been saved.
The docs explain this relationship
(Developer/Documentation/CoreAudio/AudioUnit). The AUBase classes
we
provide support this automatically if you are using them

Hi all,
I get a warning from the AU validation tool:
---------------------------------------------------------------
VERIFYING CLASS INFO
WARNING: Preset name is not retained in retrieved class data
---------------------------------------------------------------
Which method is exactly called to verify that the name has not
been
retained? I don't support the ClassInfo property, so only
Restore/Save
state is available and Restore state is NOT called prior to the
warning. What exactly is happening during this "Verifying Class
Info"
check?
Cheers,
Mike
