[ I'm confused about why most AU MusicDevices report 2 output buses
[ for this property when only bus 0 seems to be active. And the
[ docs seem to say that most AUs will only provide 1 input and
[ output bus.

[ What's the story?

Good question, Robert.

What I'd like to know is this:
Which hosts are good test beds from which to see proper multi-bus AUs in action?

I guess you're talking only about MusicDevices, but I'd like to see any AU
which has multiple input busses and/or multiple output busses, and be able to
connect to these busses and test them. I went looking for multi-bus AUs the
other day and did not find anything! Even if I had found some, I don't really
know where to test them. Logic allows for side-chains in their own effects,
but I don't know if it supports AUs with side-chains. And I also don't know
what to expect from multiple-output busses, but that is less interesting at the
moment.

I tried AudioUnitHosting.app from the SDK, and the AUVerification command, but
neither of these allow me to verify additional busses.
