At a cost of how much additional CPU overhead compared to 128 or 256 ?
The MOTU USB device has an extreme increase in overhead on OS9 running at
the smaller buffer sizes, for example.
If these smaller buffer sizes are not suitable for a certain situation, then
added latency may not be desirable. For example with FFTs where you need to
do a whole buffer at once, you cannot reduce the latency below the FFT
buffer size, and adding an additional buffer of latency the size of the FFT
may not be desirable.
