The this is counter to all of my experiences with DAWs then. I don't
know how all this buffer stuff works well enough to really give
examples, but all I know is if my CPU is running out of gas with too
many plug-ins or software synths, etc.... on any of my DAW applications,
(i.e. I'm getting clicks, pops, drop outs, etc...) I can go into the
ASIO control panel, and turn up the buffers (ie. which adds latency) and
then get more out of the same CPU. I can get a lot more work out of the
same CPU with 1024 buffers than with 64, etc, etc....

But live audio does have to pass through any buffers twice correct?
Once on the way in, and again on the way out?
