[LAA] Qtractor 0.6.3 - The Armed Hadron beta release!

Ah, the equinox...

Twice a year a cherished planetary alignment checks in on schedule,
once again.

The little rock gets another round from its warmy solar furnax, from
which were forged. The pale blue dot gets yet another round and to no
surprise, another tinier dot gets here around:

Qtractor 0.6.3 (armed hadron beta) is now released!

Release highlights:
* Revamped mixer (un)dockable panels (NEW)
* Plugin preset selection sub-menu (NEW)
* LV2 Time position/transport event support (NEW)
* Constrained plugin multi-instantiation (FIX)
* Automation curve node resolution (FIX)

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.

nb. Despite the old Qt4 stance, but still recommended, Qtractor does
build, runs and does it all on Qt5 for quite some time now. However, the
former recommendation prevails as the despicable LV2 plugin GUI
X11/embedding support through libSUIL just does NOT work on modern Qt5.

- source tarball:

- source package (openSUSE 13.1):

- binary packages (openSUSE 13.1):

- quick start guide & user manual (still outdated, see wiki):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.

- Make the mouse-wheel to scroll the plugin list views, when not
hovering a direct-access parameter slider.
- Mixer widget gets (un)dockable Inputs and Outputs panels, also with
their respective title captions.
- Plugin instantiation is now constrained as much to prevent any audio
channel output overriding.
- Existing plugin presets may now be selected right(-click) from plugin
list context-menu (ticket by Harry van Haaren, thanks).
- So-called "painting" over multiple selected event values, while on the
MIDI clip editor view pane below the main piano-roll (eg. note
velocities, controller values, etc.) is now split into two similar
painting modes, whether the sub-menu Edit/Select Mode/Edit Draw is set
on (free-hand) or off (linear).
- Drag-and-copy of plug-in instances across tracks or buses (ie.
cloning) now also copies the direct access parameter setting (ticket by
Holger Marzen, thanks).
- File/Save As... now prompts and suggests an incremental backup name
for existing sessions files.
- Zooming in/out increment is now augmented by whether shift /ctrl
keyboard modifiers are set (on a ticket request by
Holger Marzen, thanks).
- LV2 Time position event messages for plugin atom ports that support it
is now being implemented.
- Attempt to break extremely long audio [message continues]

Fixed a DSP bug that caused audio distortion in the Local Audio
Adapter device for ALSA.

Various other bug fixes. See the ChangeLog for details.

Database Update:
This version of Rivendell uses database schema version 239, and will
automatically upgrade any earlier versions. To see the current

[LAA] [ANN] Super Announcement - All MOD software for your PC

Mon, 2014-12-08 09:40
From: Gianfranco Ceccolini <gianfranco@...>
Subject: [LAA] [ANN] Super Announcement - All MOD software for your PC
Date: Sep 18, 6:50 am 2014

Hello Linux Audio Users and Developers

In less than an our the MOD Duo Kickstarter campaign will go live and so it is with great pleasure that the MOD Team makes the announcement of the desktop versions for our entire software suite.

Some of this software has already been announced in the past but, as part of our Kickstarter campaign, we put the necessary effort to have them running in a regular Linux environment and not just inside the MOD. All instructions in Github were also updated in order to yield working elements when followed.

Most of this software has been under development for almost two years and their history is related to the development of the MOD itself. Being so, they carry some differences in workflow when compared to other LV2 programs and our current effort is being put on correcting those differences.

The softwares are:

MOD Client - run your LV2 plugins using the MOD interface.


MOD SDK - plugin interface creator

Use this program to create the HTML interface required by the MOD Client. If you don’t create an interface the plugins still work, but their icons will be a tuna fish can with just the ON/OFF button. When you click on the gear symbol on the upper right side of the icon you have access to the Plugin Settings Screen in which all parameters are visible.

The MOD SDK is Python based and can be installed by typing “pip install modsdk”

As the MOD Client, it runs on your browser and requires a mod-workspace folder (or link) in which you place your LV2 bundles.

Just run “modsdk" in your terminal and point your browser to localhost:9000

There is also post on our blog about the SDK:


LV2BM - tool for analyzing and benchmarking LV2 plugins

Allows to select which URIs to test

Uses minimum, maximum and default control values to run the plugins

Uses several controls combinations in the full test mode

The output shows the JACK load percent



LV2 port of the CAPS suite of LADSPA plugins.

- TAP-LV2 -
LV2 port of the TAP suite of LADSPA plugins.

- Pitch shifters -
Capo - up to 7 semitones up pitch shifting
SuperCapo - up to 24 semitones up pitch shifting
Drop - up to 12 semitones down pitch shifting
SuperWhammy - continuous pitch shifting from -12 to 24 semitones
Harmonizer - scale interval generator

- Utilities -
Switchbox - A/B box for audio signal routing
SwitchTrigger - 4 excluding channel selector
ToggleSwitch - 4 non-excluding channel selector
Gain (mono and stereo)
Filters (LP, HP and BP) - 1st, 2nd and 3rd order
Two way mono crossover - 1st, 2nd and 3rd order
Three way mono crossover - 1st, 2nd and 3rd order

- Distortions - mathematical simulations of classic distortion circuits
Muff Fuzz

- SopoperLooper
LV2 simplified port of the SooperLooper.

All plugins from our repository have the HTML MOD GUI included.

In our Github repository - - we also have plugins that were forked from the original repositories.

One of our aims is to trig [message continues]
