Thanks, that was very informative. (And I looked up xrun on

Woo hoo! I will shamelessly adopt that phrase into my vocabulary.
"_____" costs bank! 10 coolness points...

As the link you posted above suggests, Apple may think that < 10ms
latency is good enough - and hence no need for an RT version of Mac
OS (do I sound like I know what I'm talking about yet??... :-) This
brings up the question of why RT capability is needed in the first
place. Again based on your link above, latency below 10 ms may be
undetectable when playing soft synths (since it takes about 3 ms for
sound to travel 1 m - can you notice a difference in latency if you
move closer or further from your speakers when plugged directly into
an amp? I can't...) So that leaves the ability to playback and
record at the same time (forgot the fancy term for that ...). I can
see the usefulness of that for punching into a multitrack recording,
but Digital Performer 4 on my old powerbook can do that very easily
if I tell it where to punch in beforehand (which is not a big
limitation) - it just preloads buffers or whatever so that there is
no glitch/delay when the punch happens. Seems like a Linux DAW could
be programmed to do the same thing - so what is the great benefit of RT?

Hehe, well thanks for the tip, but I was actually not so concerned
about the "pay" part as much as the "get" part. Ardour is what it is
whether I pay for it or not. (And I would gladly make at least a
token donation if I ended up using it.) I'm more concerned about how
functional it could be if it is developed for free - I mean a man's
gotta make a living and that sounds like more than a full time job.

Thank you. I have moved on to other things now, obviously. I had my
fortune in the stock market and now live in a van down by the river;
hence my interest in a Linux machine for music, since a new Mac costs
