sorry, zero buffer does not exist in signal, this idea is ridiculous.

It exists in streamed data, or in the output of soft synth. The space
between clips on a track is "zero". The space between 2 distinct notes
emitted by a synth is "zero".

maybe it makes sens for the HostAudioSoftware to not send null signal to
plug-in when the track is empty for example... but it's regarding host , and
especially non real-time host. Nothing to do with plug-in.

This is what we're talking about, a mechanism to not send a null signal on
an empty track. It's not simply a host optimizatoin though. Consider a
plugin such a reverb with a tail. Even though a track may be empty, it may
not have been empty a second ago, and the reverb may still need to do
processing to produce it's tail. Rather than doing an expensive memset() to
feed silence to the reverb, you feed a buffer with a silent "flag".
