Well, on the level I'm discussing today, we don't actually
care. However, at other levels of the API, my worldview says:
A Port represents a single channel of audio data available for either
input or output.
And please remember that we discussed all the issues surrounding
multichannel ports when we discussed LADSPA a year ago. Unless there
is a genuinely new point of view on this, I consider that issue fully
resolved.
