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.

Fedora Jam tracking well
by Brendan Jones
Currently number 5 out of 11 for torrent downloads! Not bad for the new kid.
Its very quiet on this list at the moment, so tell us what you've been
doing with music! Fedora / Linux / recording etc etc
Me, I've been trying to organize my many samples into sfz format for
use. Also found new interest in guitar (my new schecter rocks!)
I'm no drummer, but have been studying drumming a lot lately to fill out
some triggered recordings. Would love to hear other peoples experience
in this area.
kick out the jams
