If the original problem is 'how to define a mono plugin so it can

be replicated for multichannel or polyphonic use' then I'd agree.
There is a world of difference between a plugin that is meant to

be a single-function module in a larger application (e.g. a filter

in a mixer, an envelope generator in a synth) and one that is really

a complete and probably complex application on its own, e.g. a mixer,

or a complete synthesiser.
The latter you can't 'configure' just by setting port types, unless

the concept is abused in some way to carry data that is not really

describing just a port.
And I'm not yet convinced that even the simple 'replicate a mono

plugin' problem can be solved by port types only.
How would a port type tell e.g. a multichannel limiter plugin if

it has to limit each channel separately, or use the same gain

reduction, based on the loudest one, on all ?
