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. The other is some semi-proprietary software that on... you know what, never mind it's getting off topic. > >Anyways, does the list think this is worth pursuing? > >>On Wed Feb 22 2012 at 9:10:29 PM Brian Monroe <briancmonroe at gmail.com[https://admin.fedoraproject.org/mailman/listinfo/music]> wrote: >> >> Ok, I redid all the tests, while the system was only running my DE and the >> test, and then again when I put it under duress by running a script that >> looped "du -h /" and "ls -Ral /usr/" over and over.

Hey, coming up soon!... -------- Forwarded Message -------- [Sorry for cross-posting, please distribute.] Linux Audio Conference 2015 - Call for Participation (Due to exceptional circumstances, this announcement comes a bit late, so please note the early deadline of Feb 1st for submissions. We apologize.) We are happy to announce the next issue of the Linux Audio Conference (LAC), April 9-12, 2015 @ JGU | Johannes Gutenberg University, in Mainz, Germany. http://lac.linuxaudio.org/2015/ The Linux Audio Conference is an international conference that brings together musicians, sound artists, software developers and researchers, working with Linux as an open, stable, professional platform for audio and media research and music production. LAC includes paper sessions, workshops, and a diverse program of electronic music. *Call for Papers, Workshops, Music and Installations* We invite submissions of papers addressing all areas of audio processing and media creation based on Linux and other open source software. Papers can focus on technical, artistic and scientific issues and should target developers or users. In our call for music, we are looking for works that have been produced or composed entirely/mostly using Linux and other open source music software. The online submission of papers, workshops, music and installations is now open at http://lac.linuxaudio.org/2015/participation The deadline for all submissions is Feb 1st, 2015 (23:59 HAST). You are invited to register for participation on our conference website. There you will find up-to-date instructions, as well as important information about dates, travel, lodging, and so on. This year's conference is hosted by the Computer Music Research Group (Bereich Musikinformatik) at the IKM (Institut für Kunstgeschichte und Musikwissenschaft) of the Johannes Gutenberg University (JGU) at Mainz. Being founded in 1991, our research group has been among the first German academic institutions in this interdisciplinary field at the intersection of music, mathematics, computer science and media technology. In our media lab students are working almost exclusively with Linux, and in our research we are also devoted to contributing to the growing body of open source audio and computer music software. http://www.musikwissenschaft.uni-mainz.de/Musikinformatik/ We look forward to your submissions and hope to meet you in Mainz in April! Sincerely, The LAC 2015 Organizing Team

vst-dssi and wine
by Martin Tarenskeen 02 Feb '15

02 Feb '15

Hi, FYI Some time ago I reported a problem with (among others) these great VST plugins: http://kunz.corrupt.ch/products/tal-u-no-lx http://kunz.corrupt.ch/products/tal-chorus-lx using wine and DSSI-VST or Festige. The plugins would crash, where they were working fine in older versions of wine. Some other plugins on the market may have suffered from this bug too. With wine version 1.2.34 that's now in Fedora 21 things have started to work again! This is good news. But there is a problem with the display of the patchnames in TAL-U-NO-LX-V2. The fonts look strange and are hardly readable. But at least I can use the plugin again. -- MT
