Hi Urs,
Thanks for that clarification - but I think the problem may be on both
sides... I'm sure I read that the bus specified in the
kAudioUnitProperty_SetRenderCallback was the output bus but now
everything is pointing to it being the input bus - which makes more
sense. I probably got tangled between the callback proc and the
AudioUnitRender proc - their APIs are very similar.
However - I've now switched over to the "right" way of doing it. And
I'm using a different AUInstrument (PhatMATIK Pro) which has 8 output
buses. But now if I connect any of the additional buses I get an
AudioUnitRender error of -1. Connecting Bus 0 works just fine....
-1 seems like a pretty fundamental error - but I'm not sure what it
means...
Robert.

Zebra (for example) is returning 2 buses but if I try to connect bus
1 (the second bus) to the mixer I get kAudioUnitErr_InvalidElement.
And most AU instruments are returning more than one output bus.
Sorry, I had it set to 1, but then, after having difficulties with
Input, I tried 2 and forgot setting it back.
Since Zebra doesn't make use of busses, the next release will have 1
bus only again.
What am I missing?
Nothing. You are correct, I (we?) were wrong.
Cheers,
;) Urs
