I'm not convinced..

How does this affect in-place vs not in-place?  All that means is that the
input buffer is the same as the output buffer, no?  If the plugin has to
buffer, it has to buffer, regardless...I'm not a DSP head, so here is where
I may be missing stuff.

What does that have to do with mix/no mix?   maybe I am missing something,
again?

Like a piece of hardware, what comes out a port is entirely decided by the
plugin.  If it mixes in some dry signal, it probably has a wet/dry control.
Some may choose not to provide any dry signal at all.  What does mix mean
for them?
