Denormal protection for the LV2 and VST plugins was left out by
mistake from the 1.2.0 release. Version 1.2.1 fixes this. There is no
need to update the OS X version as the Jack clients were not modified.

The holiday season is over and I actually took advantage of it by not
working on this month's round-up but by making music. With the help of
Leigh Dyer's outstanding seq24 tutorials I'm trying to master seq24 and
so far I'm really enthusiastic about this sequencer. I've started
remixing an older track of mine and seq24 has already proven itself a
very valuable tool.
But I did read up on relevant mailinglists and forums to keep in pace
with the developments in Linux Audio Land. And December did yield some
interesting topics, like the RT_GROUP_SCHED option (cgroups) discussion
on the Jack-Devel mailinglist and the refutation that CPU frequency
scaling has no use for low-latency real-time audio, and then there was
the sheer amount of music made with Linux of course!
PS. Thanks to the people from LinuxMAO, without them I'd miss out on a
lot of developments, releases and other non-trivial events worth mentioning!
I am proud to introduce a new version of Foo YC-20, the Yamaha YC-20
The main udpates in version 1.2.0 are:
- LV2 plugin
- VSTi plugin (and standalone Jack client) for Windows
- OS X build (standalone Jack client)
- Improved volume control curve
- Fixed bug with 4' drawbar bleed
- More subtle hover highlights
- Switch GUI to use GTK directly without GTKmm
It is worth noting that the plugins allow finer control of the drawbar
positions than the standalone GUI offers.
Big thanks to Robin Gareus for the work on the OS X build!

The YC-20 is a divide-down combo organ designed in the late 60's. This
emulation faithfully copies the sound, features and flaws of the
Main features of this synthesizer:
* 61 keys
* Two main voice sections
* Switchable bass section
* No polyphony restrictions
* A realism control to add flaws found in the real organ
* Takes quite a bit of CPU power
* No touch vibrato
The emulation is written in Faust and uses Jack for audio and MIDI.
All controls of the synthesizer can be controlled with MIDI.
There is an undocumented "easter egg". Any command line argument given
to the program will be used as the configuration file name. The state
of the organ controls are read from the file and the file will be
overwritten with the current setup when the synthesizer is shut down.

so i lied, bluffed all the way, so what? should I be sorry? what you'd
expect from this one self-called ber-procrastinator ? and then there's
hope. alas, not the messiah, rather my development drive at my own pace.
believe it or not, it is on-going and it will sure happen real soon ;)
no sweat. The whole automation prophecy will be realized and delivered.
yes, TYOQA just failed, slipped a bit. it doesn't mean it was abandoned
though or, uh, procrastinated... well, it's only a happy new year after
the road to automation is being already being paved and walked although,
i must say, it is no yellow-bricked one. the drive has begun.
definitely, 2011 will be TYOQA (aha, read that again with a bold tee:)!
more than automation, which infrastructure is already lurking in there,
trus me, all work is being carried out at the backyard for the time being.
blossoms might just pop out this spring ;)
one thing i may wish to leave sound and clear: it is very likely that,
in the very near future, that there will be some dot-release before the
all-mighty-one release, whatever. now that the surprise-effect is gone,
the long overdue and hailed beta release cycle that will present you and
carve its deeds on stone with the dynamic-curves and automation features
et al., will be nothing less nor before the coming version numbered as
the 0.5.x scheme. then, and only then, the current alpha-cycle will be
concluded. of course, that will be also the time for translations to be
called in. just be a little more patient :)
and then i lied a second time, when said those parodied f&d release
code-names were exhausted. thanks to a lengthy but intermittent
fall/winter-of-coding period, i had the chance to wake up one morning
with the imagination score in its lowest end and roar an inner WTH! as
they say around here, there's no second without a third. so another lie
is there waiting to be told. or is it not? there, one would say: time
* Archive/Zip session file bundle (save as... .qtz) (NEW)

and a few more assorted features and fixes--see below the complete
(boring) change-log for gruesome details.
Qtractor 0.4.8 (fiery demigoddess) released!
- source tarball:
- source package (openSUSE 11.3):
- binary packages (openSUSE 11.3):
- user manual (archeologically dated):
Weblog (upstream support):
Qtractor is free, openosource software, distributed under the terms of
the GNU General Public License (GPL) version 2 or later.
- MIDI controller mapping/learn is now possible on all mixer controls
(monitor, gain, panning, record, mute, solo).
- An internal rewrite (aka. refactoring) have been carried out, making
sure that all track state action buttons (R, M, S) are now all under the
observer pattern umbrella.
- Single track range selection is now available on main menu
(Edit/Select/Track Range; default keyboard shortcut: Ctrl+Shift+R);
additionally to vertical range and horizontal track actions
(Edit/Select/Range, Track) all these operations can now toggle over the
- Direct clip selection from Files list item has been brute-forcefully
implemented (after being challenged by Jiri Prochaszka aka Anchakor:).
- Files tree widget sticky "New Group" item fixed.
- A new menu option has been added (View/Tool Tips) to show/hide a
floating tool-tip while dragging, moving, resizing or pasting selected
clips or events over the main tracks view and MIDI clip editor
(piano-roll) respectively, displaying current target position and status.
- Attempt to reset audio/MIDI time drift compensator on every engine
start and loop turnaround.
- Moving the punch-out marker over the main track time ruler was failing
to shrink the punch-in/out range, now it does (not).
- MIDI clip tools (quantize, transpose, normalize, randomize, resize,
rescale and the new timeshift) are now all accessible from the main
tracks view (Edit/Clip/Tools menu) and apply to all events on current
- LV2 Persist extension support is being introduced.
- A new timeshift MIDI tool has been added, after an awesome patch by
Jiri Prochaszka aka Anchakor; applies to selected events between edit
markers, distorting their time and duration (optionally), either slowing
down and accelerating, based on a given parameter P value.
- Audio clip/buffer pitch-shifting fixes with regard to latency
correction due on the RubberBand library one-pass (real-time) processing
- New Send Gain and Dry/Wet control parameters have been implemented for
audio Inserts pseudo-plugins.
- MIDI channel/master volume enqueued events are now affected by the
current track/bus volume (0-100%).
- Prevent old rounding error when resetting to plugin parameter default
value with the mouse middle-button click while hovering a slider widget
- A quantize percentage has been added to MIDI clip editor quantize tool
(Tool/Quantize...) for time and duration quantization (0% for none; 100%
for full regular quantization).
- Metronome bus/ports are now created at engine start and not when user
switches it on anymore.
- Make sure all audio clip buffers are in sync upon smooth-ramping going
off and playback is rolling.
- Copy-pasting across controller event types is now possible on the MIDI
clip editor (aka piano-roll).
- Finally indulged, the genuine transport stop button makes its
appearance on main toolbar and menu.
- Main tracks grid visibility option (View/Snap/Grid).
- Yet another off-by-one (frame) audio buffer bug got squashed away:
rare symptom was that some audio clips were being left dead silent right
after playback of their first looping period.
- Plugin parameter name/label now a proper attribute of its respective
MIDI Controller observer instance, allowing to be shown on dialog title
- Default session file format saved on JACK session demand is now the
bundle archive/zip one (.qtz).
- Plugin selection dialog now shows whether a plugin features its own
editor (GUI) and/or external state configuration (EXT).
- Help/Shortcuts... window positioning and sizing are now preserved.
- All plugin chain changes over the track properties dialog now sure
counts as a dirty action (possibly fixing bug #3104129).
- Newly extracted archive/zip session directories are now removed
automatically from the file-system on session close, prompting the user
for confirmation (cf. View/Options.../Display/Confirm Removals).
- Ctrl+mouse-wheel is now set for zooming in/out, on main track-view and
all applicable MIDI clip editor views (piano-roll), according to current
zoom mode (see View/Zoom Horizontal, Vertical or All for both ways
- New MIDI clip editor (piano-roll) mouse hovering effect (eye-candy++).
- After too many a user request, a brand new session archive file type
is being introduced (.qtz) which tries to bundle in one single zip
archive all the media and contents of a session.
- Add that to eye-candy: either loop or punch-in/out outer ranges are
now shaded on the main track-view, thumb-view and MIDI clip editor
- LV2 GTK UI plug-in hosting is now roaring its ugly head (EXPERIMENTAL).
- Ignore all initial and decremental notifications of audio engine's
- Internal audio buffer loop points were not being set properly for
non-zero clip offsets, leaving some as severely out-of-sync while
rolling over loop turns. Now fixed again, hopefully.
- Avoid audio peak file clashing when deriving from audio sample files
with distinct absolute paths but the very same file (base)name.
- A new MIDI editor (piano-roll) tool has been added: Rescale event
times, durations and/or values by a percentage between 1 and 1000%
(adapted thanks to patch #3081954, by Jesse Lucas).
- Attempt to mitigate audio clip sequencing glitches on
cheers && enjoy (be happy!)

This list is meant to be a place to discuss about audio development, in the
context of music and sound applications, but also games and other apps which use
audio on Android.
Discussions and questions about both Java and native APIs are welcome.
In addition to application-level topics, we are interested in discussing about
Android audio system internals, for educational purposes, as well as finding new
ways to work with sound on Android.
So please come and join us if audio development on Android interests you.
gst123-0.1.4 has been released.
Overview of changes in gst123-0.1.4:
* Fixed crash for "dumb" terminals. [Siddhesh Poyarekar]
What is gst123?
The program gst123 is designed to be a more flexible command line player in the
spirit of ogg123 and mpg123, based on gstreamer. It plays all file formats
gstreamer understands, so if you have a music collection which contains
different file formats, like flac, ogg and mp3, you can use gst123 to play all
your music files.
Since gst123-0.1.0 support for watching videos has been added; however gst123
should run fine in situations where no X11 display is available; videos can be
played without X11 display, too (-x, --novideo); in this case, only the audio
stream will be played.
It is implemented in C++ and licensed under the GNU LGPL version 2

I'm happy to announce the first public release of gx_head.
gx_head is a simple guitar mono tube amplifier simulation based
on the work we have done in the guitarix project.
gx_head provide 3 tube models (12AX7, 12AU7, 6V6)
and 8 different tonestack models(Bassman, Twin Reverb, Princeton, JCM-800,
JCM-2000, M-Lead, M2199, AC30), so you can simply create the amp-model
to your needs.
gx_head comes with a bunch of in-build effects, like distortion, crybaby,
autowah, phaser, flanger, echo, delay, . . .
The effects could ordered in two Racks, on for the mono effects, witch
could be load for pre or post processing, and one for the stereo
effects, witch could only used in post processing.
Effects are loadable over the menu, a pop-up menu in the racks, or a
plugin bar. Settings could saved/load as presets.
gx_head comes with some factory settings provided by guitarix/gx_head
friend "funkmuscle", thanks therefore.
All UI controllers could connected with jack midi via MIDI learn with
your external MIDI controllers.
gx_head is ready for language support via gettext() and comes thanks to
Pablo Fernández with a Spanish translation.
The style file gx2 is contributed by zettberlin, thanks Hartmut
some features in short:
* 8 tonestack models
* 3 tube models
* cabinet impulse response module
* bass boster
* easy Impulse Response file support via zita-convolver
* on the fly IR-file resampling via zita-resampler
* Oscilloscope and tuner
* multi band distortion model
* scalable EQ
* phaser, flanger, stereo delay, stereo echo,
* overdrive, compressor, freeverb, reverb,
* chorus, moog filter, low/high pass filter, . .
* MIDI learn
* Patch Info widget
* Preset File Load/Export option
* factory settings
* language support
* shining User Interface via GTK/gtkmm
* . . . .
gx_head is licensed under the GPL.
please report bugs and suggestions in our forum here:
For extra Impulse Responses, gx_head uses the
zita-convolver library, and,
for resampling we use zita-resampler,
both written by Fons Adriaensen.
We use the marvellous faust compiler to build the amp and effects and will say
: Julius Smith
: Albert Graef
: Yann Orlary
For faust users :
All used Faust dsp files are included in /gx_head/src/faust,
the resulting .cc files are in /gx_head/src/faust-cc
The tools we use to convert (post-processing and plot)
the resulting faust cpp files to the needed include format,
stay in the /gx_head/tools directory.

Standing on the shoulders of giants[*], I am pleased to announce the
public release of IR, a convolution reverb in the LV2 plugin format.
Released as free software under the GNU GPL, this easy to use plugin
has been created to open the fascinating world of convolution reverb
to Linux-based audio engineers. If you use Ardour to create, mix &
produce music, you will most probably want to check out this plugin.
* Zero-latency operation
* Support for mono, stereo and 'True Stereo' (4-channel) impulses
* Realtime operation
* Very reasonable CPU consumption
* Maximum impulse length: 1M samples (~22 seconds @ 48kHz)
* Loads a large number of audio file formats
* High quality sample rate conversion of impulse responses
* Stretch control (via high quality SRC in one step integrated with
* Pre-delay control (0-2000 ms)
* Stereo width control of input signal & impulse response (0-150%)
* Envelope alteration with immediate visual feedback: Attack
time/percent, Envelope, Length
* Reverse impulse response
* Autogain: change impulses without having to adjust 'Wet gain'
* Impulse response visualization (linear/logarithmic scale, peak & RMS)
* Easy interface for fast browsing and loading impulse responses
IR should work on Linux with Ardour 2.8.x (x >= 11) and 3.
