Hi :)
could you please add a dependency to audio/MIDI app packages for your
distros, that will set up real-time usage?
The following issue is wide spread:

Be sure you are able to run audio apps with the
right
privileges, eg.

for the n-hundreth time: nice has no role to play in improving the
performance of pro-audio/music creation software.
You'll read such 'help' thousands of times when you're subscribed to
regular distro users mailing lists or on non-audio Linux forums.
I always post
http://www.jackaudio.org/linux_rt_config when I read such
recommendations.
Since people usually are using Jack by a package, when thy use real-time
audio apps IMO it's ok to include it to a Jack package, anyway, IMO
there should be a dependency setting without nice and with memlock.
I just want to inform about this issue. Coders and package builder might
not be informed about what happens on non-audio users lists and forums.
FWIW very often there are recommendations to _avoid_ a kernel-rt, since
a distros 'default', 'desktop', 'generic' kernel should have the
same
capabilities and the kernel-rt should have disadvantages. The resume
then could be, that people wonder, that they can't use Linux for complex
audio sessions.
Alas, the stock Debian kernel these days does *not* use "Low Latency
Desktop" :(
I don't know if derivatives have followed suit or not...
