Would you like 40 more effect plugins?
After many months of persistence I have ported the Rakarrack effects to lv2
format. With each effect, the individual effect presets have been ported as
well. I am very excited about this project and hope that this can keep the
Rakarrack project as one of the highlights of linux audio. Rakarrack is
currently in need of a proper maintainer. So if you are interested please
contact the developers! I made these ports such that all changes could be
ported back into the main codebase.
The porting took a lot of manual entry of matching parameter bounds and
indices etc.. So as you test and use these, please report any strange
behaviour you notice (such as changing the "gain" parameter actually
changed the decay time, etc.). I will be trying to test these but it will
take me quite some time to give them all a good shake down.Current status
is that they all can be loaded by Carla and Jalv, with some audio testing
on a few by me, and some testing by other parties. No known issues
I am currently working on porting the preset banks to Carla rack presets.
This will allow us to load any of the presets from Rakarrack and insert it
as a single plugin in Ardour or other hosts. I would like to get the
community started testing these in parallel with my effort. Once I have
that done I will announce a second beta.
Not all of the effects were ported, since some were duplicate code, direct
copies of ladspa plugins, or redundant of other lv2 plugins (like the
looper or colvolotron). The interface was kept close to Rakarrack, but some
parameter changes were made for the intent of clarity, such as wet/dry -
instead of the original -64 is all wet, 0 a 50/50 wet/dry mix, 63 dry, now
0 means all wet, 127 all dry. Parameter names were altered in places as
well (e.g. St. Df. now is labeled "Left/Right LFO delay"). Case by case
feedback on these decisions is also welcome.
For those unfamiliar with Rakarrack, here are all the effects, marked to
show which are in this new plugin bundle:
EFFECTS (X - done, W - won't do, + - done with missing features)
[X] Lineal EQ
[W] Overdrive - exact same engine as distortion, but has fewer controls,
presets were added to dist.
[W] Phaser - I'm not planning to do this. I'm only interested in the analog
[X] Analog Phaser
[W] Flanger - this is identical to the chorus, presets from this will be
[X] Parametric EQ
[X] Cabinet Emulation
[X] AutoPan/Stereo Expander
[+] Harmonizer - midi mode was not ported
[X] Musical Delay
[W] Noise Gate - Direct copy of Steve Harris's Gate ladspa plugin
[X] Dual Flange
[W] Convolotron - other excellent lv2 convolution engines already exist
[W] Looper - other good lv2 loopers exist
[X] StompBox - an extra plugin for fuzz mode was added, as interface is
[+] StereoHarm - no midi mode
Further help using them can be found at

enjoyable, and make great music with them.

Stepping up to Summer'15 release frenzy stage scene, in it's fourth and
hopefully last act,
Qtractor 0.7.0 (muon base beta) is out!
Qtractor  is an audio/MIDI multi-track sequencer application written
in C++ with the Qt 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.
As a major highlight to this release, there's the advent of regular MIDI
controllers mapping/assignment to main application menu command actions,
just like normal PC-keyboard shortcuts, is being introduced (cf. main
Have a 'hotta' Summer'15 ;)
- source tarball:
- source package (openSUSE 13.2):
- binary packages (openSUSE 13.2):
- wiki (help wanted!):
Weblog (upstream support):
Qtractor  is free, open-source Linux Audio  software,
distributed under the terms of the GNU General Public License (GPL )
version 2 or later.
- Complete rewrite of Qt4 vs. Qt5 configure builds.
- Revised MIDI Controlllers catch-up algorithm.
- Mixer multi-row layout gets a little bit of a fairness fix.
- Non-continuous MIDI Controllers now have their Hook and Latch options
disabled as those are found not applicable,
- As an alternative to PC-keyboard shortcuts, MIDI controllers are now
also assignable and configurable for any of the main menu command
actions, all from the same old configuration dialog (Help/Shortcuts...).
- Fixed missing Track and Clip sub-menus from Edit/context-menu that
were found AWOL ever since after the Lazy Tachyon beta release (> 0.6.6).
- An off-by-one bar position (as in BBT, bar, beat and ticks) has been
purportedly fixed as long as LV2 Time/Position atom event transfer goes.
- French (fr) translation line to desktop file added (patch by Olivier
- A new top-level widget window geometry state save and restore
sub-routine is now in effect.
- Improved MIDI clip editor resilience across tempo and time-signature
- Keyboard shortcuts configuration (Help/Shortcuts...) now lists
complete menu/action path where available.
- Fixed in-flight VST plugin editor (GUI) resizing.
- Added support to LV2UI_portMap extension, found really handy for the
cases where you have multiple plugins with different port configurations
and a single common UI to drive them all (pull request by Hanspeter
Portner aka. ventosus, thanks).

The 2nd Web Audio Conference (WAC) will be held April 4-6, 2016 at Georgia Tech in Atlanta.
The Internet has become much more than a simple storage and delivery network for audio files, as modern web browsers on desktop and mobile devices bring new user experiences and interaction opportunities. New and emerging web technologies and standards now allow applications to create and manipulate sound in real-time at near-native speeds, enabling the creation of a new generation of web-based applications that mimic the capabilities of desktop software while leveraging unique opportunities afforded by the web in areas such as social collaboration, user experience, cloud computing, and portability. The Web Audio Conference focuses on innovative work by artists, researchers, and engineers in industry and academia, highlighting new standards, tools, APIs, and practices as well as innovative web audio applications for musical performance, education, research, collaboration, and production.

x42-plugins is a collection of cross platform LV2 audio/midi plugins,
currently featuring over 80 plugins from 11 repositories.
Changes since the last release (20150530)
* All plugins
- now have LV2 required version numbers
- feature built-in documentation/description
Plugin descriptions are now 100% spec conform and survived
pedantic inspection by the LV2 high inquisitor (falkTX ['s script]).
There have been various small build-system and packaging tweaks reported
by distros in the wake of the previous release last month.
Many thanks to Jaromir Mikes (debian), Edgar Aichinger (openSuSe) and
Filipe Coelho (KXstudio).
Likewise portability has been further improved. While developed an
targeted at GNU/Linux, all plugins now on run reliably on all major OS
and support over 20 CPU architectures.
Thanks to Jean-Luc Nest, Chris Goddart and Harrisonconsoles for QA on
OSX and Windows.
* sisco.lv2 (Simple Scope)
- allow to vertically align individual channels
* meters.lv2 (Audio Signal Meters)
- EBUr128 GUI: improved drawing performance (partial exposure)
- new Bit Meter (inspired by bitmeter the jack app)
- scalable GUI for the 30band 1/3 oct spectrum analyzer
- drawing improvements for the Goniometer "dot" mode.
- fix some invalid ranges min <= default <= max.
- remove units from port-names, use lv2:unit
* OSC controllable standalone jack applications (simple LV2 host)
are now compiled and deployed by default for the following:
+ x42-eq (mono + stereo variant)
+ x42-meter (collection of all meter.lv2)
+ x42-mixtri (mixer/trigger pre-processor)
(x42-scope was previously available as standalone jack app)
- incl man-pages and --osc-doc built-it doc
- possibility to set initial port-values
- featuring port latency compensation
For a complete list of changes, please see the individual repositories:
Kudos to Fons Adriaensen, some of the DSP code goes back to him and he
provided very valuable feedback and advise throughout the development of
what became x42-plugins over the years.
Also to David Robillard who laid the LV2 groundwork and made portable
free audio-plugins a possibility in the first place.
Last but not least, many thanks to libremusicproduction.com and
libregraphicsworld.org for continued support and publicity.
Please pardon cross-posting. I am pleased to announce the availability of
csound.node. This addon for NW.js implements the complete integration of
Csound and HTML5 on desktop platforms. It has been tested on WIndows and
The same capabilities are available in current versions of CsoundQt and
Csound for Android, but csound.node is easier to build and supports the
development of standalone applications such as sound art and computer music
installations, visual music pieces, self-contained interactive
compositions, kiosk-type applications, and so on.
For for more information, including build instructions and configuration,
Prebuilt binaries and examples are available in the Windows installer at
(this still requires installing NW.js and some configuration). On other
platforms, building csound.node should be simple.
A version of this Windows installer with all VST features of Csound enabled
(Cabbage, vst4cs for hosting VST plugins in Csound, and CsoundVST) will
soon be available on my Web site, http://michaelgogins.tumblr.com.
