:) I know - as you've said, and I am jealous, because it's not working
as well on my machine. There are more than a couple of permutations I
have not yet tried, but it really should work with the same buffering
settings as I use with CSAV, shouldn't it?

I have heeded Istvan's advice, and have tried all combinations of -b
and -B one might think of, and monitored the control panel of my
soundcard/interface as the case may be, to see that -B (samples per
hdwr buffer) settings are reflected, and still no improvement.  I'm a
fulltime programmer and have been using csound actively since 97, so I
would THINK I'd be able to track it down by now, but I'm at a loss. :)

Things I still need to try:
1) I have a suspicion that the ASIO stuff installed with Cubase is
conflicting somehow with csound.  I obviously don't know enough about
ASIO/VST to articulate that accurately - part of the problem.  I need
to take a day, uninstall Cubase and anything associated with it, as
well as all csound stuff, and see if performance changes with ONLY cs5
and drivers for my soundcard.

2) I don't understand why changing the ksmps to 1 (kr=sr) makes things
so much worse in CS5.  If I have kr=sr, the crackling from latency is
really bad.  It improves somewhat with ksmps=10, but not much.  Here's
my test orc/sco

orc:
sr=44100
ksmps=10
nchnls=1

	instr 1	;untitled

ain1	inch	1
out	ain1
	endin

sco:

i1 0 3600


3) I may have a stray portaudio dll on my machine that is introducing
the latency.

=-=-=-=-

Also - just to be clear - RT output of _any_ orc/sco I've written is
fine.  It's input that is the problem.  I would expect to hear the
signal produce by the above orc/sco to hit the output clearly with
less than .1 sec of delay.  Am I expecting too much?

Viktor:  Are your pieces always processing RT input?  I could see that
if your music is not rhythmically active, you might not notice the
latency we do.

Thanks for the feedback -- and thanks, Bill, for piping up!
