its certainly not documented, but not much is. it doesn't serve any
purpose other than being one of the several approaches one could take
with this somewhat unusual (but certainly not wrong) i/o
configuration. basically, ardour has the concept of "data streams"
within the signal processing route. imagine the situation *without*
the plugin for a moment: what happens to the "extra" data streams C &
D that don't obviously map to the outputs? executive decision: add
them to the outputs (and do it badly, by adding C *and* D to both
outputs, just for good measure). add the plugin to the situation ....
presumably ardour should know that there are now really just two data
streams post-plugin and that nothing needs to be done. but it appears
that it doesn't discover this, and this may be intentional but more
likely is just a bug.
