Hello!
I understand what you mean Bill, nevertheless it seems to me that what Marc
said sounded right too, isn't it? Even if the host is actually looking
at one of my "other" busses, is there a way to tell it that those busses
have different SupportedNumChannels than main busses??
Or should we consider that this property is reserved for main busses? It
could be great if such a "negotiation" concerning formats could exist
for all the busses...
Thank you!
Pierre-Jean

I think the problem you have (and I'm ignoring the other one) is that
the host is probably not looking at your bus count so doesn't know
that you have a second "side-chain" input bus...

Hmmm, I think this might be something you could consider a bug in

SDK. Buses are referenced by "element", right? So when someone
Gets the
SupportedNumChannels property, the element argument is supposed to
specify
the bus index, correct? It is ignored in
AUBase::DispatchGetProperty and
DispatchGetPropertyInfo, and also of course not passed along as an
argument to the SupportedNumChannels method, so I guess there is an
assumption that the property is the same for all buses, which to me
doesn't seem a valid assumption. I think that the SupportedNumChannels
should have another argument specifying the element and the Dispatch
methods you pass that along, but maybe I'm wrong about this, I haven't
tried multiple buses yet...

Hi all!
I don't really get how "side-chain" and "supportedNumChannels" should
"interact". Here is the problem :
my plug can do mono/stereo and stereo/stereo on main input bus/main
output bus. That's what I answer when querried about
kAudioUnitProperty_SupportedNumChannels.
But what should I do to give the host a hint that, for example, I
can do
mono/stereo and stereo/stereo too for side-chain in and out buses?
Thanks!
