thanks you ! :-), it was me who wanted such a feature, cause on a real time
audioworkstation, i consider that the host must keep the integrity of the
audio stream, and if the last inserted plug-in causes a DSP overload, then
it has to be disconnected from the chain. The fact is that feature finally
concernes more the Host than the plug-in ... so we can forget this
requirement.

yes , of course ! :-) i just think it's useless. When you work in real time
, it is to hear the true result, not a decayed one.
