Hi Jeremy,
Isn't searching the email archives a pain in the derriere? I've
requested the Apple web guys switch to a modern email archive system
(something like mamasam would be awesome). They received my request
politely but no changes yet. It would be a lovely gift for the next
developers conference though :-)
The "pull on the busses to find the bad ones" was a guess - sorry to
hear it doesn't work - and it means we're really up a creek. There are
more and more AU instruments with multiple output busses so we've got
to support them...
I wonder if the validator would detect this?
Robert.

Robert,
Thanks. I found the original post 'AU output buses' but I cannot find
Marc's reply. If the culprit is a parameter named numOutputs that is
really numBusses why not change the name?
I have looked in depth into this but I am not using AU graph's. I do
not see any error when trying to render on busses greater than 0.

Hi Jeremy,
I brought this issue up a few weeks ago and there was a bit of
discussion but then it went away. The culprit seemed to be identified
by Marc (as usual) as the numOutputs parameter to the AUBase
constructor. Most people are thinking it is asking for channel count
when it's actually asking for bus count. This makes it a bit nasty
for us host developers - I guess we can try pulling on the various
busses and those that complain should be dropped from the available
set? Bit of a pain though...
BTW I think it would be great if Apple reworked the DLS Synth to
support multiple output busses (with routable instruments) (not just
the dry/wet outputs) - it would make it a lot more useful for users
and a good example of multi-out for host developers.

First of all, Happy New Year to all of you on this list and thank you
to the contributors for the wealth of information contained here!
I would just like to query this list about the AU busses. It has come
to my attention that a bunch of plug-ins are setting there output
buss
count to 2 and then their stream counts to 2 or more even though
rendering audio on any buss other than buss 0 produces either silence
or noise.
Is there any reason for this? Is this an artifact of the Emagic SDK?
Is
there a way that AU Validator can test for this?
Thanks,
Jeremy
