Low Latency vs. Real Time Kernel - actual latencies ?
by Be 06 Apr '15

06 Apr '15

Hello Fedora musicians, I've been lurking this list for a little bit and this is my first time chiming in on something. I think it is important to pursue an official realtime kernel for Fedora. I think a distribution focused on audio without a realtime kernel would have a serious bug, that IMO, would be worth delaying publication for. >So I had a beer with hansomepirate(jdulaney), who is, or was on the kernel sig, last night and we got to talking about a RT kernel. > >Last time we talked to the kernel folks about an rt kernel, they weren't impressed with the "need" for Fedora, but that was before the Spin was officially out. > >Now might be a good time to raise this issue again? I dug through my archives and found this thread. Now that we have an actual spin that's out, we can actually redo some of the testing to have more realistic tests. (multitrack with effects) > >I feel like right now, it's one of the few benefits that the ubuntu studio folks have (or at least claim to have) over us.

Some of the names of the real time kernel developers listed on the PlanetCCRMA kernel-rt page are Red Hat employees. I would like to see Fedora be the premier linux distribution for music. But until we can overcome the concerns listed in the Musician's Guide we will probably not have a real time kernel in the Fedora repositories. Maybe a Fedora "Re-Mix", or Fedora.Next and Workstation with the works with Fedora software library may break the ice. -- Jeff

New Jack
by Orcan Ogetbil 29 Nov '14

29 Nov '14

Hi all, I had some spare time to do some updates on rawhide and F-21. So I updated jack to 1.9.10. The qjackctl and qsynth packages were a little outdated. I updated them as well. Feel free to test and leave karma. Best, Orcan

Documentation updated
by Brendan Jones 20 Nov '14

20 Nov '14

As some of you have probably noticed, the spin won't be included this release on the spins page. This is because we didn't do the testing in time. The nightly composes are still creating the spin (and will always be up to date with the latest packages rather than a snapshot at release time). We also have the new "Audio Production" yum group which allows you to install the audio packages on a system with your desktop environment of choice. I have updated the pages here [1] and here [2]: [1] https://fedoraproject.org/wiki/Fedora_Jam_Audio_Spin [2] https://fedoraproject.org/wiki/Fedora_jam

NAMM Show(s)
by Brian Monroe 19 Nov '14

19 Nov '14

I wanted to reach out to the list and ask a quick question: I'm looking to have RedHat join NAMM (National Association of Music Makers), I'm also involved with Fedora Ambassadors and I wanted to know if anyone here is interested in going to either of the NAMM shows to promote Fedora/OpenSource there. I live pretty close to Anaheim so the costs are almost non-existent for me and I'm even willing to pitch in to help cover the cost of getting in. There's a lot of cool stuff at NAMM, including all of this years new gear, but we need some people (musicians/musos) that are interested in reaching out to a new group that knows little to nothing about FOSS. There are two shows: One is January 22-25, in Anaheim, CA, and the other is July 9-11, in Nashville TN. (Potentially there's a third and fourth show in Russia in September, but I don't have exact dates, additional fees, or locations for those, and there will probably be an addition cost but still let me know if you're interested in attending those or are conencted with APAC or EMEA as I'm not sure what Russia would fall under). We have four tickets, but I'm not sure if RedHat will be sending anyone, or if I already have a second person to help me. At this point I'm not sure if there's going to be any money provided to help out with travel costs, but it's a possibility so right now I'm looking for people that are able and willing to attend with the intention of discussing Fedora over gawking at all the shiny and free stuff (there will still be plenty of time for that).

NON-sequencer release
by The name of my band is 1984 12 Nov '14

12 Nov '14

hi, i've been back playing with the NON-* suite in the last days. i've realized that the non-sequencer is 1.2.0 . according to the author, 1.9.2 should be used as stable. is there any particular reason why 1.2.0 is still pakaged? i've compiled successfully the 1.9.2, but i had to search the internet for missing ntk dependencies... http://linuxmusicians.com/viewtopic.php?f=1&t=11107 http://libremusicproduction.com/articles/friday-interview-4-jonathan-liles cheers max

ardour and ardour3 packages
by Brian Monroe 11 Nov '14

11 Nov '14

Can someone enlighten me why we forked these packages with the naming scheme this way? I know that the licensing changed from the version 2 and version 3 releases and caused us to package them separately, but it seems to me like it's backwards. Is there a fedora policy that would prohibit us from packaging ardour3 under the package name ardour and ardour ver 2 under ardour2. I can see this as being a potentially sore spot for new users to try to install Ardour with "yum install ardour" and being disappointed and or confused with why Fedora is a whole version behind. Or bewildered when they start using the program and it doesn't look right and the menus are all wrong according to the website.

Low Latency vs. Real Time Kernel
by Brian Monroe 11 Nov '14

11 Nov '14

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.

Broken dependencies for ladish tools?
by The name of my band is 1984 06 Nov '14

06 Nov '14

hi, i've installed gladish and the ladish tools but something seems to be broken. running ladi-control-center from the command line claimed for xdg library. i've fixed the issue installing pyxdg, xdg-user-dirs, xdg-utils. actually, i'm not sure about xdg-*, since now the system does not allow me to remove them since it seems they are used from other applications. i had to fix also the JACK conf tool in gladish-->Tools-->Settings. it was ladiconf (file not found), fixed using ladi-control-center same for ladi tray: i had to install python-appindicator (and related dependencies), libappindicator (and related dependencies), libappindicato-gtk3 (and related dependencies) to get it working now it seems to be ok max
