sure, thats a good high level description of what ardour is doing. but
think about what this actually means in practice: it means that your
chaining logic is actually responsible for plugin instantiation (and
destruction). a given plugin "unit" might have 1, 2 or more actual
plugin instances within it. but if plugin instantiation is being done
from within the chaining logic, how does it share code that the host
might use that overlaps with this in some way?
