- Thread-topic: Dynamically notify a DAW about a change in parameter info
Hi,
Is there a way our
AUMIDIEffectBase can notify the host dynamically about a change in
AudioUnitParameterInfo besides plug-in initialization phase?
So as a result we’ll get a call
AUBase::getParamaterInfo().
i.e: When our
AudioUnitParameterInfo changes entirely, including
maxValue from 1000 to 2 (from continuous to toggle control),
we call AUParameterListenerNotify(),
and as a result the host calls
AUBase::getParameter()
which updates only the parameter’s value.
A side effect will result in a wrong display in the automation lane.
Thanks,
Doron & Oshrat
