Hello,
Does anyone know of a good plugin that will generate subharmonics?
I would like to put a little more low frequency "oomph" into my bass
track. Preferrable LADSPA, but VST would work, too.
Thanks for any help!

Hey everyone!
Let's get this straight! I only hear rumors. It is already January. Usually
the call for papers starts December.
Is the organization of the event simple slightly late or is LAC2016 not
happening this year?

Hi,
This is an original song I recently submitted for the OSMP Tunestorm, huge
thanks to ssj71 for a fun podcast with a bunch of great submissions!
Listen to podcast here: https://archive.org/details/OSMP73
I also wanted to use this song as demo of Harrison Mixbus3 on the upcoming
AV Linux 2016 so I screencasted the session for people to see what is
being used, lots of great work by our Linux Audio developers is contained
within!

Hi,
First of all, let me introduce myself. I'm Theo, and while I'm new to
linux audio, I'm not new to linux perse (20+Y), and in general can find
my way around the system quite easily. Up until recently I've not had
much reason to delve into linux audio as It "just worked" for what I use
it for - listening to music while doing stuff behind the PC - which I
happen to do quite often as I'm working as a geneticist/bio-informatician.
And then something changed. I bought a new laptop, and found the audio
quality "lacking" to say the least. So I went to the shop and got myself
a USB external sound card with reasonable sound quality and - worth
bonus points - a 6.35mm headphone jack instead of a 3.5mm jack, a volume
control dial and an extra pair of rca outputs so I can also connect it
to my stereo. I plugged it in and found out it didn't "just work".
So I started reading up and was stupefied - it was an alien world to me,
with a new language (ok, new slang) and apparently several "competing"
ways of doing things. To make this manageable for myself I decided to
take things one step at a time. I first installed jack/qjackct, qsynth
and found a midi keyboard and got it to produce sound after some small
tweaks. Things have definitely changed a great deal since I last handled
a DX7 - and it was great fun. In the process I found out that channel 1
and 2 of my USB sound thingy went to the rca outputs and channel 3 and 4
to the headphone jack. No problem.
Then I started gstreamer - no output. So I made some more tweaks as per
google's suggestions, then gstreamer outputs appeared in qjackctl, and
after making the necessary connections from gstreamer to outputs 3 and 4
I had sound again. Great. Then the next song started playing and the
sound ceased. So I made the connections again in qjackctl and I had
sound again. This happened a few times, I got a bit annoyed and
discovered the patch bay. I tried it, and it didn't work on my usb
thingy while it worked flawlessly on my built-in sound card. Every time
a new song started, the connections in qjackctl automatically reverted
to output channels 1 and 2 (rca jacks) and disconnected channels 3 and 4
(headphone) even though there was a patch-bay active. Now, I was almost
ready to file a bug report when I noticed that the patch bay did work
after a restart of gstreamer - for one song only.
It was then that I realized that every song a new out_jackaudiosinkN_1
and out_jackaudiosinkN_2 appeared in qjackctl, with N an increasing
integer. So in the patch bay I added out_jackaudiosink2_1,
out_jackaudiosink2_2, out_jackaudiosink5_1 and out_jackaudiosink5_2, and
connected them to my headphone outputs, and sure enough, after every
restart of gstreamer I could hear the second and fifth number, while all
other songs were silent. Quite a bit of fiddling later I found out that
one can actually use regular expressions in the patch-bay. Connecting
out_jackaudiosink[0-9]+_1 and out_jackaudiosink[0-9]+_2 to channel 3 and
4 works. Wonderful. I now reliably get output through my headphones
after a new song starts. Only thing is that now I get four connections -
the (apparently) default connections to channels 1 and 2 are also
reconnected every time a new song starts.
So, to come to my questions:
- Am I the only one using 4-channel external USB sound card with
gstreamer? When I saw it's specs I was convinced that everyone would
want one as a sort of "audio docking station" - better quality audio and
no more annoying physical (un)plugging to re-route audio through an
amplifier on the wrong side of the room instead of headphones.
- What is the point of this (re-)connection behaviour of gstreamer? -
gstreamer doesn't suddenly become a "new device" when it starts playing
a new song.
- I guess gstreamer does the out_jackaudiosinkN_x numbering, correct?
VLC seems to handle this differently (and this is actually how I found
out about the regular expressions)
- How can I tell the software (gstreamer + jack) to do what I want and
not more? Simply a connection from gstreamer to my headphones (channel 3
and 4), and NOT to my RCA connectors as well unless I tell it to. This
last question may appear a bit mute as it now "just works" in my main
use case (headphones), but it bugs me that I have a device that would
perfectly allow me to keep my amplifier plugged in ready to roll at a
software flick of switch, but if I would, every new song starting would
automatically come blaring out of my speakers. I guess that others have
bumped in this as well - in particular people doing DJ-ing from from
linux (do they exist?) would get very annoyed by sound coming out the
wrong way every time a new song starts.
- I found little in terms of usable documentation for multi-output
set-ups. I'm for instance not convinced that I would be able to
configure the system to use both on-board and external usb sound-cards
simultaneously. Did I miss something here? Can anyone point me to some
relevant documentation or is there a real issue here? Also the regular
expressions bit - quite neat - but I just stumbled upon its' use in
another program, and is not something I read about.
In general I'm both impressed by and worried about the state of linux
audio - a lot is possible but to get things working is (imho) much
harder than it should be.
regards, Theo.
Hi lists,
I've been using Ubuntu Studio for a while now, lately with the KX repos added.
Then I had to take my regular computer to service and since anyway I must fool
around with a backup device I decided to give KXstudio a spin (also because
I'm curious about KDE).
Apart from obvious theme and software differences, it seems that KX ships
without a default (automatic) software updater / manager. Is that a feature or
a glitch? Any reason not to install Muon?
The KX website [1] is somewhat outdated. Is the project still active?
And would it be an idea to do some kind of merge between Ubuntu Studio and KX?
I really like Ubuntu Studio, but I also like working on an up to date
Ardour...

All the best,
Alf
Hi all,
here's a little cheery tune I just finished, which I recorded with a
hardware digital recorder and then arranged and mixed on Linux.
https://soundcloud.com/spotlightkid/restless
All sounds are from a little hardware synth, the Mutable Instruments
Shruthi-1, which is a digital-analog hybrid monophonic desktop synth
module. I used the version with the "4 Pole Mission" filter board and,
for one sound, one with a SSM2044 filter.
On the software side, only some is Open Source. My main DAW is Tracktion
6, which is proprietary but runs natively on Linux. In this track,
besides the usual mixing, editing and automation features, I used its
built-in sampler an its great step sequencer clip feature for the drum
programming. Open Source software used was Calf vintage delay,
zita-reverb, ZamComp and Carla.
Share & Enjoy!
Chris

The ONLY Linux distro I've ever used that had any kind of automatic software updater is Ubuntu. Do others?
And I really consider such a thing something to avoid. Have had too many updates "update" a working setup to a non-working setup.
KDE is a resource-heavy desktop. I'd rather have my processor and memory free of such a load.

All,
As some of you may be already aware, this past December I was notified
our current virtual server that hosts a broad array of outreach
services, including these mailing lists, will be decommissioned at the
end of this month. Since, I've been working on securing the
infrastructure and ongoing support onto a brand new physical blade. I am
pleased to report we are at the very end of what has proven to be a
fairly intense journey (needless to mention I learned a lot more than I
ever wanted to about sysadmin). Our new setup is considerably more
powerful and I am confident it will offer a significant improvement in
performance over the old one. As we enter the final stage in the porting
process, there will be a brief downtime tentatively scheduled for 11am
Eastern Time (East US Coast) tomorrow, Wednesday, January 27th. During
this time, you will experience inability to access hosted services,
including web and mailing lists. My intent is to have the transition
complete as quickly as we can do the final rsync and IP address
reconfiguration. I will let you know as soon as we've completed this
final step. Thank you for your support and understanding.
Best,

I've just read that dice have sold off slashdot and sourceforge.
Interestingly the new boss has said he thinks mistakes were made with
sourceforge which he intends to roll back.
Dice say the reason for the sale is that it no longer fits their profile. I
suspect that translates as "We can't make obscene profits out of you guys"
Some of you may have noticed that github was offline for a few hours recently so
in my view maintaining a presence on sourceforge is good insurance. Also,
their built-in bug reporting is very useful. There doesn't seem to be an
equivalent in github.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
Ahoy there!
Qtractor 0.7.4 (the tackiest gluon) has been released!
Y'all know the drill...
Qtractor [1] is an audio/MIDI multi-track sequencer application
written in C++ with the Qt framework [2]. Target platform is Linux,
where the Jack Audio Connection Kit (JACK [3]) for audio and the
Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main
infrastructures to evolve as a fairly-featured Linux desktop audio
workstation GUI, specially dedicated to the personal home-studio.
Change-log (since last release):
- Eye-candy warning: muted/non-soloed tracks are now shaded over the
main thumb-view.
- Faster and crispier VST plugin editor (GUI) idle cycles.
- Fixed all core processing when any plugin has more audio outputs than
channels on a track/bus where it's inserted.
- Added one decimal digit to all percentage input spin-boxes on the MIDI
Tools dialog.
- Added brand new and global option to disable the so called "catch-up"
default behavior (cf. View/Controllers.../Sync).
- Fixed some track control issues related to MIDI Controllers generic
mapping (cf. View/Controllers...).
- Try making Help/Shortcuts... dialog window modeless, as far as under
MIDI Controller, Inputs/Outputs Connections window also gets accessible
enough.
- Fixed some vertical scrolling and play-head line re-drawing glitches
introduced by the recent unlimited slack to editing beyond current
contents length on main tracks view.
- Added one decimal digit to the Pitch-shift spin-box on audio
Clip/Edit... properties dialog window.
- Added application keywords to freedesktop.org's AppData.
- Fixed local keyboard shortcuts on the Files organizer widget actions
and context-menu.
- Improved Mixer multi-row layout (patch by Holger Marzen aka. bluebell,
thanks).
- Fixed the Ctrl+drag/cloning left of a clip when towards near the
beginning of session.
