Hi,
the documentation and examples for AU are excellent, all the changes
since the Hamburg kitchen are welcome.
However, I have few notes:
- MIDI controllers assignment, especially the default one, has no sense
for usual application, hosting many plug-ins. In this case the
controllers should be mapped globally across all effects. Maybe I don't
fully understand the goal of such mapping.
- Why do we use UInt32 structure members for each byte of midi event?
Storing large buffers of events requires some overhead.
- I haven't found mp3/mp4 converter in Apple components, currently all
this functionality should be done using Quicktime, does Apple plan to
add such (highly optimized) format converter audiounit?
- The new concept of OS X is splitting one file with many resources
into various files in folder, appearing to be a file. In case of
components, there are resources, binaries and few plists, but user as
well as developer absolutly has no idea, what is in the package,
opening the folder in Finder.
Why not to add at least an XML (plist) for each component describing
the audiounits included inside?

I still do not succeed. Are AudioUnits supposed to be single files or
are they folders?
What am I supposed to do after building the two
example projects (MultitapAU.pbroj and SampleEffect.pbproj)? Logging
out and back don't make them appear in AudioUnitHosting either.
I am working on a freshly installed X 10.2 (German language), DevTools
July 2002 + August update, AudioCore SDK 1.0. Though target settings
in
PB suggest the examples will be installed in my
Home/Library/Audio...Components folder, nothing at all appears there.
Am I missing something?

Do not post admin requests to the list. They will be ignored.
In the finder they appear as single files, but they really are
CFBundle directories. Look in the "build" directory for each of your
projects and you should find the built components. You then need to
copy them into Home/Library/Audio...Components
(or /System/Library/Components -- must be root for this one)
then logout, log back in and you should be good...
