Hi Jim,
The AU behaviour is with respect to the difference in the APIs the same as
VST. AU max frames tracks the HW I/O buffers in the case of realtime
streaming, and a much larger setting for offline processing.
An update, demo and other stuff can be found at

Cheers,
Sven

Hey Sven, thanks for the response! I was about to email you directly
with the same findings. I had just compiled the test results when
Marc's message about the max frames per slice came in, so I figured
I'd just post what I had to the list since it was relevant. Anyway,
I'm glad to hear this is fixed in Spark 2.81. I'll download it and
check it out. So, in 2.81 is the AU behavior the same as VST in this
regard, i.e. AU max frames per slice tracks the HW I/O buffer size
the same way that blockSize does for VST?
Thanks,
Jim

There was a bug in 2.8 which let to above "strange" behaviour. It is fixed

In 2.81 the AU effect will always be informed about maximum number of
