| Hello Stefan,
Thank you for replying.
As you can imagine, my concern is that many plug-in developers will only test with Apple Logic and therefore will expect this behavior from an AudioUnit host. Therefore IMHO, either it should be part of the AU specification or Logic should not do it.

As Bill already wrote, you do not have to do this for AUs. The Logic engine does it because it does handle other plug-in formats as well (e.g. TDM and our built-in plug-ins) and in some of these formats it's necessary to do this. The generic plug-in handling layer doesn't know what particular format a given plug-in has, so it tears them all down, even if it wouldn't have to do so for AUs.
Best, Stefan
