Pulse is easy to get rid of, systemd not so much unless you replace it
with something else. At some point you would be using systemd if you
want something to start with no user input.
At present I'm running with the standard Ubuntu kernel, and will see
if there is a need for the low-latency
kernel once I get it up and running.
You may wish to stop cron. Ubuntu uses cron and utilities that depend
on cron. While cron does run with nice, there seem to be some
operations ubuntu does with it that are atomic enough to disturb
sound. (at least in the past when I tested it) I have not tried
softsynth operation on a regular kernel, so I can't really say. I have
found for my uses that I could get by with higher latency with
softsynth than I can with guitar effects. I think it will depend on
your keyboard player. Some of the mechanical pipe organs had a rather
long delay from keypress to sound anyway.
Len, many thanks for above, and previous email. Some useful tips there!
Cron I can do without, no problem.
I don't expect that there will be any need to connect in during a
performance. I anticipate any remote access
I can simply use ssh to get in. If there is any real work needing to be
done I will plug in a monitor, mouse
and keyboard.
No-one has said I should go with jack-dbus, so I'll stick with jackd,
and should be able to sort things out.
I'll have to experiment with setting up headless. A worst I can always
hide a small monitor inside the case!
I have seen people running GrandOrgue on organs similar to what I'm
aiming for, with a touch screen monitor
on top of the case, so it's not absolutely essential to go headless.
