Audiounit I/O Buffer Size

Hi

I wish I could get hold of the Hardware buffer size from within a audio unit. I know I should not be dependen on this and that I should 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.

Thanks,
