finally I gather from all of your responses that when my aumu in

Yeah. We've recently discussed a lot of stuff like this, where still a
lot of VST specifics seem to cloud some of our thinking. Some of the
AU
specific paradigms have yet to be implemented by plugin/host
developers...
You should provide any input / side chain or multiple outs in form of
busses. This should be preferred over a single bus with multiple
channels. However, AUBase is currently limitted in that those
additional Busses can't be queried for ChannelInfo Arrays.
I think that you're overstating this a bit. It's not always
appropriate
to offer multiple ins and outs as different buses, only if you have
some
sort of sets of ins or outs. Like if you have a main input and a
modulating sidechain input, then you'd use two buses. But each one
might
have several channels. And for multiple outs, you only want to use
separate buses if they are, for example, separate outputs for separate
internal instruments (as you were talking about before), but each
output
bus again might have multiple channels. Anyway, I know that you
realize
this, but I think that what you're talking about probably doesn't
apply to
Kent and that you the way you said it made it sound a little more
general
than you indended, so I just wanted to clarify so that Kent doesn't go
off
making a separate bus for every audio channel!

He Marc,
yeah, you are right, I was talking in general, just as an example where
some things are still in transition, merely thinking-wise than
specs-wise. Nevertheless, assuming an 8 channel output Bus being
2/2/1/1/1/1 is weird in that context...
Btw. I have just tested SideChain on a Music Device with Logic.
HasInput(0) is always false, regardless what you do to assign a
SideChain (using Busses, setting Track Output to "no output", all the
stuff). Same for HasInput(1), when I checked if it was that (as a
common side chain in a common effect should go there, right?).
I couldn't find any weird stuff in the Baseclasses, so I guess this is
indeed a Logic issue...
Funny: Even when giving back {2,2} as single possible ChannelInfo
configuration, Logic lists that device twice in the instruments menu...
Cheers,
;) Urs
