Hi Robert,
I thought I should mention that you might want to investigate dropping
the use of an AUGraph in Rax.
One of the projects I'm working on (on the side for now) is a
performance-oriented sequencer that mostly uses AUs for the audio
generation mechanism. I decided early on to write my own audio engine
and call the AU render procs directly. It turns out that this is really
pretty easy, and you gain total control over the situation. It probably
took no more than a week to get the basic audio buss management and
mixing up and running.
My point is that if you're going to be writing a mixer, you might as
well do it in a way to gives you the most flexibility and power. On the
other hand, it wouldn't the so easily reuseable in other programs. (But
by the time you need it somewhere else, Apple will probably have their
new mixer out ;)
Cheers

Hi Bill,
Sorry if it seems that I've been whining - but the mixer discussion
did seem a bit one sided for a while ;-). I'm sure you guys are very
busy.
And now you've made me very curious about the missing piece you've
alluded to...
Meanwhile I'm trying to educate myself a bit - but perhaps with this
missing piece you're hinting maybe I should wait? - and build a simple
mixer just to get my hands dirty.
The first question I've got is: Shouldn't I be using an AUKernel to do
the little bit of DSP on the input busses to the mixer? But AUKernels
seem to be associated with AUEffects (it's in AUEffectBase,h) Is that
just a bit of housekeeping or is there something that tightly couples
AUKernels to AUEffects?
Thanks,
Robert.
