I think you're missing the very obvious situation I was thinking of
Tom.
Imagine a data stream from disk coming into an Ardour mixer strip
(using the visual model here), and then being sent as part of a submix
to a bus. Another mixer strip reads from the bus, does "global"
processing on the submix, and then sends it out to a physical
channel.
At the moment, the data emerging from the channel will be delayed by
one engine cycle. Not good.
