can you expand on precisely what you mean by that?

ardour doesn't support LADSPA plugins that do not support
PROCESS_INPLACE, or VST plugins that do not have processReplacing()
methods. hence, yes, input buffer is always the same as the output
buffer. if a plugin can't handle that, it should not be marked as being
capable of doing inplace processing.
