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)
Here is the first release of jackwsmeter.
This is a small utility that gets the signal values of the audio that
flow through JACK ports and make the peak levels available over a
websocket link, it's a clean and efficient way to get an overview of
levels from a serie of jack servers.
It's available in git at http://repo.or.cz/w/jackwsmeter.git, it's
released under the GNU GPL v2 or later.
The release tag is http://repo.or.cz/w/jackwsmeter.git/tag/refs/tags/1
I hope it can be useful to some people.
A stable release, version 14.07, of MMA--Musical MIDI Accompaniment
is available for downloading. In addition to a number of bug fixes
and optimizations, MMA now features:
- Works with Python 2.7 or 3.x
- Plectrum articulate
- MIDI enhancements
- Lots of minor enhancements and bug fixes
Please read the file text/CHANGES-13 for a complete list of changes.
MMA is a accompaniment generator -- it creates midi tracks
for a soloist to perform with. User supplied files contain
pattern selections, chords, and MMA directives. For full details

So it's summer, they say.
White bright and light pastel colors sparkling on every corner and turn.
Cheesy and silly season, they say. Alas, southerners don't apply. Sorry
about that. Of course I mean the hemisphere, obviously.
For whom it might concern, all anxiety has come to an end.
It all relates back to this last May 3, when a not-so-formal meeting
(aka. workshop) took place while during LAC2014@ZKM-Karlsruhe, where
some pertinent and undeniable requests were dodged and framed to a
"soonish" implementation. And guess what?
Yup, the "soonish" are no more, or so I think.
Qtractor 0.6.2 (boson walk beta) is out!
Perhaps an additional word is due though, about the riddling code-names
that are branding the post-TYOQA beta releases. They have no personal
nor logical sense, I assure you. Perfectly arbitrary now. Everything in
life and the universe is way more unconventional than just a name.
Without further assay.
Qtractor is an audio/MIDI multi-track sequencer application written in
C++ with the Qt4 framework. Target platform is Linux, where the Jack
Audio Connection Kit (JACK) for audio and the Advanced Linux Sound
Architecture (ALSA) for MIDI are the main infrastructures to evolve as a
fairly-featured Linux desktop audio workstation GUI, specially dedicated
to the personal home-studio.
* Plugins activation MIDI controller / automation (NEW)
* LV2 UI Idle and Show (>= Qt5) interface support (NEW)
* Discrete editing of automation curve node velues (NEW)
* Missing audio/MIDI files and plugins warning message (NEW)
* MIDI note drawing on tempo-map changes (FIX)
* Automation curves re-adjusted to tempo-map changes (FIX)
- source tarball:
- source package (openSUSE 13.1):
- binary packages (openSUSE 13.1):
- quick start guide & user manual (severely outdated, see wiki):
- wiki (help wanted!):
Weblog (upstream support):
Qtractor is free, open-source software, distributed under the terms
of the GNU General Public License (GPL) version 2 or later.
- Prevent linear and spline automation curve modes for all integer
valued subjects. Also, make sure those values are rounded to the nearest
integer away from zero.
- Fixed save of LV2 Presets for plugins with state files.
- A man page has beed added (making up Gürkan Sengün's work on debian,
- When moving plugins by eg. drag-and-dropping across tracks, automation
curves were being left behind, maybe leading to unpredictable mistaken
behavior. Hopefully, not anymore.
- Translations install directory change.
- Automation curves are now automatically re-adjusted to tempo map node
changes (after a ticket by Holger Marzen, thanks).
- Audio/MIDI files or plugins found missing on session load are now
subject for an explicit modal warning message and prompt for an
immediate session backup salvage.
- Changing instrument plugin programs is now an undo/redo-able command
operation, especially for DSSI but also for plugins that come with the
LV2 Programs interface extension support
- Drawing, selecting and/or resizing of MIDI note events that extend
across tempo/time-signature changes is now made a bit more correctly
over the MIDI clip editor (aka. piano-roll), especially regarding to
current snap-to-beat setting (after an outstanding ticket by yubatake,
- Once again, audio frame/MIDI time drift correction has been slightly
refactored to improve MIDI input monitor and timing.
- Discrete automation curve node values may now be edited via a
numerical entry floating spin-box on double-click (as yet another
request by AutoStatic aka. Jeremy Jongepier, thanks).
- Pressing shift/ctrl keyboard modifiers while double-clicking on a
plugin list entry now briefly reverses the current
View/Options.../Plugins/Editor/Open plugin's editor (GUI) by default
- Fixed an old crash lurker when switching output buses that implied a
change on the number of audio channels, while on tracks that have
(auto-)monitor turned on and at least one active plugin in chain (yet
another ticket by AutoStatic aka. Jeremy Jongepier, thanks).
- MIDI Controller assignment (aka MIDI learn) and/or automation of
plugins (de)activation state has been added (as requested by AutoStatic
aka. Jeremy Jongepier, thanks).
- LV2 UI Idle and Show interfaces support added.
- Allow the build system to include an user specified LDFLAGS (patch by
Alessio Treglia aka. quadrispro, thanks).
Enjoy && have (lots of) fun.

The Guitarix developers proudly present
Guitarix release 0.30.0
For the uninitiated, Guitarix is a tube amplifier simulation for
jack (Linux), with an additional mono and a stereo effect rack.
Guitarix includes a large list of plugins, support LADSPA plugs, and
now, new, as well LV2 plugs.
The guitarix engine is designed for LIVE usage, and feature ultra fast,
glitch and click free, preset switching, full Midi and/or remote
controllable (Web UI not included in the distributed tar ball).
Preset could organized in Banks, so a Bank could represent your "show".
If you have any issue with Preset loading/creating/handling, please read
here in our wiki how this stuff work in guitarix. It is straightforward,
and maybe more intuitive then you guess.
This release fix some bugs in our faust based zita-rev1 implementation,
add LV2 support to the guitarix racks and introduce some new plugs, GX
based and as well in the LV2 format.
* GxDetune (gx / LV2)
* Baxandall tonestack(gx)
* GxShimmizita ( LV2)
* GxSwitchedTremolo (LV2)
