The first unified LV2 release, LV2 1.0.0, is out.
This release merges the previous lv2core package with all the official
extension packages, as well as example plugins, lv2specgen, and
additional data. From a developer point of view, the biggest change is
that all LV2 API headers can be used by simply checking for the single
pkg-config package "lv2" (for compatibility the previous "lv2core"
package is still installed). Implementations are encouraged to abandon
the "copy paste headers" practice and depend on this package instead.
With this release, several new extensions have become stable that
together greatly increase the power of LV2: atom, log, parameters,
patch, port-groups, port-props, resize-port, state, time, worker.

QMidiArp 0.5.2 has just seen the light of the day. It brings mainly
two improvements. One is a comeback, that of tempo changes on the fly,
and that now includes also tempo changes of a potential Jack Transport
master. Also the Jack Transport starting position is finally taken into
account, so that QMidiArp should be in sync also when starting the
transport master not at zero.
The second one is Non Session Manager support, mainly thanks to the work done by Roy Vegard Ovesen!
Note that for compiling in NSM support you will now need liblo as dependency.
Enjoy, and enjoy LAC in Graz this year
QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO.
Everything is on
o Tempo changes are again possible while running, both manually or by
a Jack Transport Master
o Jack Transport position is now taken into account when starting,
QMidiArp used to start always at zero
o Muting and sequencer parameter changes can be deferred to pattern
end using a new toolbutton
o Modules in the Global Storage window have mute/defer buttons
o Global Storage location switches can be set to affect only the pattern
o Non Session Manager support with "switch" capability (thanks to
Roy Vegard Ovesen)
o NSM support requires liblo development headers (liblo-dev package)

Reinstatement of two features that got lost in the mist.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
I’m pleased to announce the next public beta release of GlassCoder, a
minimalist JACK live encoder client for Icecast and Shoutcast streaming
servers. GlassCoder is available under the GNU Public License version
2. Some features available in this beta release:
Support for Icecast (v2) and Shoutcast (v1) streaming audio servers
Support for the following audio codecs:
MPEG-1/1.5 Layer 2 ('MP2')
MPEG-1/1.5 Layer 3 ('MP3')
MPEG-2 Advanced Audio Coding, Main Profile ('AAC')
MPEG-4 Advanced Audio Coding, High Efficiency Profile ('HE-AAC+')
Support for the JACK Audio Connection Kit (http://www.jackaudio.org)
GlassCoder is a ‘minimalist’ client in the sense that it utilizes no GUI
or configuration file components whatever; its entire ‘user interface’
consists of a command-line invocation, making it particularly
well-suited for use cases where the encoder is driven by fan external
system, such as an automation system or script. Full documentation is
provided by the included man page.

I made a delay where you don't tap in a tempo but an actual rhythm.
The 'much more' refers to ways of manipulating the sound of the
In the studio, I find that I almost never use a straight delay.
It sounds way to clean and in your face, so I usually have a combination
of filters, a widener, reverb, and a way of having different delay-times
for L and R.
Here I combined all that into one very flexible setup:
Each tap has its own lp and hp-filters, zita-reverb, stereo-width and a
Each tap can have it's own settings for the insert-FX, but instead of a
control-panel per tap I made just two, and a slider per tap to morph
Once you get the concept, it's a really quick and easy way of making
everything from subtle polished delay effects to all-out dub-style
The following is a long-winded question that will probably be much
easier to follow if you actually try out the effect before/ while
I'd love to get some opinions and ideas on the feedback mechanism I
In particular this: when the feedback amount is non-zero, and you are
tapping a new rhythm, while making sound, I have two choices:
- either I turn on and off the feedback tap after the feedback-delay.
- or I do it before it.
The first option is what I did now: it has the effect of starting to
feedback the sound you just made right after you tap. Which is what
you'd expect to happen in a normal delay, but has the downside that it
breaks up the rhythmic pattern you're tapping if any tap is longer than
The second option will only start feedbacking the sounds you made after
you hit the tap button. This has the effect that the first time you tap
a new rhythm, only the tapped rhythm is heard, and the feedback only
starts for any sounds after the last tap.
This decision is moot if you don't make sounds while tapping a new
rhythm, but since I'd like to be able to use this live as well, I'd like
to some ideas.
The video recordings of the LAC'14 presentations have just been uploaded
to the conference website and are now directly linked from the archive:
There are still a three videos missing and the workshop videos are also
yet to come. Currently they are also only available as vp8/vorbis/webm
(sorry IE and Safari users). But since it has been quite a while
already, we decided to not hold back the release of these already
finished videos any further.
Once the collection is complete, we will provide a .torrent. Meanwhile,
for those who prefer to download the videos incrementally, they are
accessible via rsync://linuxaudio.org/ .
Many thanks for Frank and Moritz to get those done in really outstanding
quality this year. Kudos to the complete stream-team.
