I've a question about this...
Who is likely to call beginEdit and endEdit?

Hi Nicolas,
I use a custom GUI with the help of Emagic's VSTAU wrapper. I
implemented the following code in the
setParameterAutomated(), beginEdit() and endEdit() VST functions. Seems
to work OK....
void CVST2AUPlugin::setParameterAutomated(long lIdx, float rVal)
{
// Set parameter and call host for automation
setParameter (lIdx, rVal);
float value = GetParameterTranslated (lIdx);
AudioUnitParameter sPar={m_AudioUnit, AudioUnitParameterID (lIdx),
kAudioUnitScope_Global, 0};
AUParameterSet (NULL, NULL, &sPar, value, 0);
}
bool CVST2AUPlugin::beginEdit (long parID)
{
AudioUnitParameter sPar={m_AudioUnit, AudioUnitParameterID
(parID),
kAudioUnitScope_Global, 0};
if (m_AudioUnitView)
m_AudioUnitView->TellListener ((AUVParameter&)(sPar),
kAudioUnitCarbonViewEvent_MouseDownInControl, NULL);
return true;
}

bool CVST2AUPlugin::endEdit (long parID)
{
AudioUnitParameter sPar={m_AudioUnit, AudioUnitParameterID (parID),
kAudioUnitScope_Global, 0};
if (m_AudioUnitView)
m_AudioUnitView->TellListener ((AUVParameter&)(sPar),
kAudioUnitCarbonViewEvent_MouseUpInControl, NULL);
return true;
}
Hope this helps,
Ben.

Hello,
I'm actually woking on an audio unit wrapper for our vst instrument,
and
I have some problems about automation in Logic.
As It's a wrapper, I have a custom gui (based on CarbonViewBase).
In Logic the automation works fine in 'control mode', then I think I
correctly implement the
GetParameterList and the GetParameterInfo functions.
But with our own gui, it doesn't work.
As Nikolaus Gerteis suggested on this list, I (try to) notify Logic on
the
beginning of the automation with a call to TellListener :
TellListener( (AUVParameter&)(au_param) ,
kAudioUnitCarbonViewEvent_MouseDownInControl , NULL )
Then during the automation (when I get an audioMasterAutomate from
VST) I do some
AUParameterSet( 0, 0, &au_param, (Float32) value , 0 ) ;
And finally
TellListener( (AUVParameter&)(au_param) ,
kAudioUnitCarbonViewEvent_MouseUpInControl , NULL )
In fact, I call the first TellListener on the first
audioMasterAutomate call, and the second when the mouse
is released.
Is it a correct way to do automation with Logic ? I must have missed
something, but I can't find what.
Any help would be great ! Thanks in advance,
Best regards,
Nicolas
