For future readers, I went ahead an implemented this by spawning adding a duplicate of the same Filter AU for every input channel.
So now I have 5 buffers -> 5 one channel FX units -> Matrix Mixer -> 2 channel output So now I have only one AU View showing for the first instance, and to make the settings match the others, I'm using: AUListenerCreateWithDispatchQueue / AUListenerAddParameter. It's probably adding a lot of processing ( several FX nodes, plus my callback to sync their settings ) but it seems to work. I'd still be interesting in knowing if there's a more straightforward way, but having studied up a bit more, I doubt it.
