Low Latency vs. Real Time Kernel
by Brian Monroe
I've been spending a lot of time on the #opensourcemusicians channel
talking to Ubuntu Studio users about their kernel and latency times they're
getting. Seems like most of them are using g a stock kernel with the
preemptive option enabled and they are getting great latency results
(2ms)while utilizing the @audio group on their user. I ended up compiling
my own low latency kernel and I haven't had any issues with it yet. If this
is what we are missing for the spin I'd be happy to maintain packaging for
the kernel. I know ccrma has been behind a few kernel releases.
I saw the instructions for adding the real time patch for a tick less
kernel and from what I can tell it wouldn't be hard to get that rolling as
well.
I'm not entirely sure what ccrma does differently with their kernels
compared to other Linux users, and I'm still a bit of a noob so I could be
off base with this, but I would reason that we should be able to just
utilize the same settings to archive similar performance enhancements.
I thought I read that ccrma uses a unique scheduler, but if we could get a
2ms latency time without it, the point may be moot.

Ideas for Banner
by Onyeibo Oku
Hellos
We're considering Fedora-Jam (spin) for highlight at
http://fedoraproject.org/ webpage for F18. I would appreciate insight
on packaged tools in the spin that can inspire a banner design on that
page. Its possible Ardour3 will be ready for F18 so a cool screenshot
from someone running the beta will be great.
What else?
Regards

A quick spin vox-pop
by Ian Malone
A week or so ago I thought I'd canvas some opinion on what people
might want from the spin. So I asked at the Rob Chapman guitar forums,
Rob is probably best known for gear demos and lessons on youtube, and
for starting a guitar company that makes collaboratively designed
guitars. So these are people who are used to community participation,
but not necessarily free software (though I probably skewed that a bit
by using their geeks forum).
Anyway, discussion seems to have finished, so here's the thread:
http://www.robchapman.tv/forum/threads/fedora-jam-music-creation-collecti...
Not a whole lot of new ideas. There are a few people already using
Linux for audio production and they are generally happy with what they
already use, not very surprising as they probably wouldn't be using it
if they weren't. However things that came up:
1. Hardware support. Not much we can do from a spin/music-list point
of view to improve driver support, but worth having advice and links
to the Alsa matrix visible somewhere. There is a lot of supported
gear, but there are people like digitalscream who've got hardware
which is unlikely to work.
2. Integration. Touched on, things need to work without too much
setup. This is even more important since it seems the spin will be the
starting point for people new to linux audio. It's not the primary
goal of the music list effort (that's really the packaging that
Brendan and others are doing), but it does serve as a showcase for
that work.

Yes, it might be necessary (and conveniently JaM could be an acronym
for Jack Music), and your setup is helpful, might also be useful for
Jørn's configuration tool. But I'm hoping there's going to be a way to
get Pulse and Jack into agreement on F18, I know it can be done in F16
