Notifying host of parameter change

Hi to all,

I'm working on an AU wrapper project.

When my example plug EditView change a parameter value, this function is called:

//==============================================================================
void myAU::informHostOfParameterChange (int index, float newValue)
{
    if (myFilter != 0)
    {
        myFilter->setParameter (index, newValue);
        AUEffectBase::SetParameter ((UInt32) index, (Float32) newValue);
    }
}

but the host does not record the parameter automation on the timeline.
On the other side , drawing a parameter automation in the track my plug is able to update its internal state.


Any help would be appreciated

best regards
Carlo Chiari
