Thanks, "non-realtime" helps a lot (I was using Steinberg's term,
"offline"). I posted that long reply to Erik before I got your
response. Now it seems like there actually are many things dependent on
working in realtime. I think the guy asking about non-realtime
rendering in this old thread was asking what I'm trying to ask now
(although oddly, I can't find the top of the thread in the archives):

If things have changed in the last 6-8 months I'm interested to hear.
I would be intrigued if, for example, JACK could now synchronize
applications and plugins to a slower- or faster-than-realtime clock,
depending on the processing power needed, or even if there were still
future plans for this.
Cheers,
Chris
P.S. If I'm not mistaken, the Steinberg equivalents of JACK, LADSPA,
and ALSA are ReWire, VST, and ASIO respectively -- somebody please
correct me if that's wrong.
