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.

WhySynth GUI not opening, although hostname is resolvable (OSC issue?)
by Sean Beeson
Hi, list.
Anyone familiar with WhySynth issues and perhaps OSC? When I run Whysynth
it starts fine and the GUI starts. Sound works, but the GUI doesn't open. I
have read this issue is caused by the computer's name not resolving, but
mine does resolve, so something else is causing this. I turned off iptables
to see if it was a firewall issue and that didn't help much.
Since the DSSI and GUI run and sound works, but the GUI doesn't show, I am
thinking it still may be an issue with a port or some other OSC issue. I am
not so familiar with trouble-shooting OSC. Anyone got any pointers on
trouble-shooting it. What utilities are there?
Could it be some other trouble?
Thanks,
Sean

First impressions of the nightly Fedora Jam
by M. Edward (Ed) Borasky
So far everything seems to be OK. I ran into a problem in the
installer selecting the boot drive, but it's already in Bugzilla so
I'm not too concerned. 19 itself seems to be solid on my workstation
and I'll probably upgrade my laptop as soon as the beta is released.
I'll try out some of the audio stuff later this week. It's been a few
months since I messed around with JACK so I doubt if I'll find any new
bugs.

Set for Fedora Jam
by twohot
Greetings
Okay, I have two boxes waiting to get a feel of Linux audio. These two
machines will be used in studios by Linux Skeptics. So, I need this
adventure to work real fine. Which way do I go? I am happy with Gnome3
DE but it looks like the Linux music world favours KDE. Does that mean
I can't have a studio running on Gnome DE?
How about Real-time kernel? Is it advisable to use the regular Fedora
release in Studios? I know about Fedora Jam. Do they stock rt-kernels?
What are the gains? I am looking to install Ardour3 on these machines
(btw, I don't see that on our repos. Why?).
Any thing else?
I'll appreciate a leading before I dive in
Regards

Rosegarden Ver. 12.04-3.fc18 Build Key 4342ef67ee Not Getting Input From MIDI Input
by Sean Beeson
Hi, List.
Is anyone using Rosegarden 12.04-3.fc18 and are they able to get anything
in through the MIDI inputs. Rosegarden is able to send note data, but it's
not seeing or not passing on note data from either a MIDI keyboard nor
Jack-Keyboard. I can use both through Jack just fine. It's always worked
for me in many previous versions by just selecting the port in the Manage
MIDI Devices window. This is the first time I have ever seen this happen.
Things like ZynAddSubFX and LMMS are working fine.
