Hi all,
when loading my AU, Logic asks for a list of AUPresets in "GetPresets"
and I provide a list of 128 AUPresets. Works fine. I can choose a
preset from within Logic.
But how can I notify Logic that this list has changed? (new presets
have been loaded by a plugin internal function).
And how can I tell the host that the user selected another preset (out
of the 128 list). I can select one of the 128 presets with Logic, but
if the users uses e.g. a program-change I would like to notify Logic
that the current preset changed. I tried:
DispatchSetProperty (kAudioUnitProperty_CurrentPreset,
kAudioUnitScope_Global, 0, &AU_Presets[i], sizeof (AUPreset));
DispatchSetProperty (kAudioUnitProperty_PresentPreset,
kAudioUnitScope_Global, 0, &AU_Presets[i], sizeof (AUPreset));
SetAFactoryPresetAsCurrent(AU_Presets[i]);
AU_Preset is an array of 128 "AUPreset"s.
"i" is the current preset-number.
I call all three functions (just to make sure) but Logic doesn't update
it's display to reflect the change.
Do I make any sense? Should I give up and lie to the host by telling
him I have no presets, so the list isn't even displayed and so the user
is forced to use my plugins internal preset-management? The downside
would be that I would be forced to put in my own preset-management into
every plugin I want to release as an AudioUnit...
Hope somebody can help me.
Cheers,
Mike
