Low Latency vs. Real Time Kernel - actual latencies ?
by Be
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.

sig, last night and we got to talking about a RT kernel.

impressed with the "need" for Fedora, but that was before the Spin was
officially out.

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.

by Fernando Lopez-Lezcano
Hey, coming up soon!...

[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
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.
