The version of X that I am using has 14 Apple supplied audio units,
including 3 output units, a couple of basic filters, a DLS synth and one
that appears to be a 64 channel mixer ...

The problem is not connecting them together and getting callbacks to work,
that has been relatively painless. I can easily create sound by configuring
the AUs to get them to call back into my app. (At least I proved it to my
satisfaction using the default output unit).

The problem is actually coding an AU 'component' itself.
The QuickTime documentation gives a lot of information but does not seem to
be 100% compatible with the methodology used for AudioUnits.

As you guys at Apple already have at least 14 components already built,
could I request that you release the source for one of them to the public
domain ??? again pretty please. Why the reticence here ? Please at least
let us know why you are not prepared to do this.
