Low Latency vs. Real Time Kernel
by Brian Monroe 10 Nov '14

10 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.

Can be found here: http://dl.fedoraproject.org/pub/alt/stage/19-RC3/Spins/x86_64/Fedora-Live-J… We had to drop dssi-vst due to multilib issues. rtirq is NOT turned on by default. Any last minute testing would be greatly appreciated. regards, Brendan

Jam On? Help with Getting Started wiki
by Brendan Jones 28 Jun '13

28 Jun '13

Hi all, assuming the wheels don't fall off at the last minute like last time, it looks like we are good to go. One thing we are going to need for the spin is a definitive 'Getting Started' page. Detail is not really appropriate for the spins donwlaod page, so I have created a skeleton page here [1]. I will request websites add a link to it in the 'Support' section. PLEASE edit - I seriously threw this together in 5 minutes from what we already have. Contributing section is still empty. Disabling desktop effects also has no link. Feel free to change all the wording etc, it would be awesome if someone could add some charm ;) I apologise in advance for not being as active this cycle with the Jam spin, I've been travelling a lot for work, visited home for a few months, and as a result I've be poorly keeping up with my packages updates let alone coordinating this spin. I'm going out of town again tomorrow, will be around for the launch on July 2, but then will be disappearing overseas again for a couple of weeks at the end of that week. If you really want to help out, join the SIG, I'll sponsor you and at the very least you'll have access to editing the wikis. No obligation! For the launch I would have liked a bit more "spin" on the spin, press etc and what not, but I just haven't had the time. I hoped that the momentum we built up over GSOC would sustain itself but no. Maybe the realization of the spin will fire things up. Anyway, thanks to all who have helped out - really appreciate it. [1] https://fedoraproject.org/wiki/Fedora_Jam_Audio_Spin Brendan

amsynth 1.4.0
by Martin Tarenskeen 24 Jun '13

24 Jun '13

Hi, amsynth-1.4.0 has been released upstream at http://code.google.com/p/amsynth/ I think it's really worth having this in Fedora. It would probably need to be split in a amsynth, amsynth-dssi, and lv2-amsynth package. I have been using test versions from GIT these months, and it's working nicely. I quote from the NEWS file: amsynth 1.4.0 -- 2013-06-23 - LV2 support added - various improvements to sound engine, including: - mono & legato keyboard modes - portamento / glide control - extended OSC 2 detune range - switchable low-pass / high-pass / band-pass filter modes - switchable 12 / 24 db/Octave filter slopes - additional LFO waveforms (sawtooth up & down) - reduced aliasaing on oscillator's square / pulse waveform - now ships with substantial library of presets, thanks to brian(a)amsynth.com - preset banks are now stored in ~/.amsynth/banks - numerous other improvements and bug fixes -- MT

F19 karma required before final freeze
by Brendan Jones 16 Jun '13

16 Jun '13

Hi all, I've systemd-ified rtirq, and I need to get it tested before the final freeze which is June 17. Also up for testing is qtractor and giada. If you could test and leave some karma that would be great. regards, Brendan https://admin.fedoraproject.org/updates/rtirq-20130402-4.fc19 https://admin.fedoraproject.org/updates/qtractor-0.5.9-1.fc19 https://admin.fedoraproject.org/updates/giada-0.7.0-2.fc19

jam kickstart update
by Ian Malone 16 Jun '13

16 Jun '13

I've just commited an update to the kickstart https://git.fedorahosted.org/cgit/music-creation.git/tree/spin-kickstarts/f… : e10dafc..d7b8865 the 'favourites' entry in the KDE menu was pointing to an old location for the QJackCtl desktop file which seems to have changed in F19. Not sure if that's the official location for Jam spin development. I have a VM with F19 Jam installed, aiming to check Brendan's updated packages for karma this evening or tomorrow. -- imalone http://ibmalone.blogspot.co.uk
