Don't be daft! I'll admit my LP filter example was less than concise.

Which group of ports? The output group from the previous plugin in the
chain? Why not just the number of channels? That's all that's needed
for the simple case I'm talking about.

Would it be worth having two extensions? One for complex examples useful
for (modular) synthesis and voice polyphony,  and another for the simple
cases such as the lp filter example?
