it's maybe a point to clarify, because i don't understand how to merge two
kind of event management on the same plug-in architecture. Or we work as
closed as the real time with the smallest possible buffer , or we work with
timestamped event and big buffer...

not completely irrelevant, we are talking about timestamped event since few
weeks, and i'm trying to explain that this technic and concept can be well
implemented only in a RTOS or Interrupt O/S . Otherwise this will be a
complete hell for Host audio developper to provide such concept under
windows for example.
