This raises an important question (in my mind, at least): If the user
sets a particular buffer size in a DAW such as Logic, does it really
matter what the hardware buffer size is? Wouldn't having too large
of a buffer in Logic defeat any advantage you might have in your AU
by using a smaller buffer based on the hardware? In other words, I
am thinking that all you need to know is the buffer size that the DAW
will use for your AU. Anything beyond that cannot be taken advantage
of, unless I am missing some detail...

I wish I could get hold of the Hardware buffer size from within a

use de GetMaxFramesPerSlice to setup my buffers.
But.... I would really like this value so I can minimize the latency
of my plugin. Since I use convolution in my audiounit, I always have
to optimize between latency en CPU heaviness.
I would like to implement some buffer size adapting internally to the
plugin (like I did for RTAS) to make sure that the plugin performs in
the best way I can imagine. So when the track of the audiounit
switches to be "live" it performs with lowest latency that makes
sense. The only value I really would to get a hold of is the I/O
buffer size as set in the preferences panel of Logic.
