That works with the existing API - { 2, 5}

we're *only* concerned here with multiple busses where the channel capabilities of those busses is *different*. (Thus, the DLS Synth has 2 output busses, but those are *always* stereo, so it reports { 0, 2 }

So what about 'panner' AUs? (say one 2-channel bus in, one 5-channel bus out)

OK - I'm just trying to conjure up an example of how to break this and I can't... Seems like a good idea to do it this way.

This implies a certain channel relationship between in and out capabilities on the same element ID...

Art,

This is a bit tricky as the num channels property is only really
generally used to describe a common channel capability across all
busses/elements.


This still seems like just a mistake in the SDK to me. Will
AUBase::SupportedNumChannels be modified in the next SDK revision to have
an Element argument so that channel configurations can be queried
per-element?

I have another example that might make more sense to you: Let's say you
have a vocoder that is designed for stereo carrier input and mono
modulator input. Currently there's no way to describe that setup unless
you hack the SDK to make SupportedNumChannels() bus-aware.
