Description:

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.

Features:

- Multi-track audio and MIDI sequencing and recording.
- Developed on pure Qt4 C++ application framework
(no Qt3 nor KDE dependencies).
- Uses JACK for audio and ALSA sequencer for MIDI
as multimedia infrastructures.
- Traditional multi-track tape recorder control paradigm.
- Audio file formats support: OGG (via libvorbis),
MP3 (via libmad, playback only), WAV, FLAC, AIFF
and many, many more (via libsndfile).
- Standard MIDI files support (format 0 and 1).
- Non-destructive, non-linear editing.
- Unlimited number of tracks per session/project.
- Unlimited number of overlapping clips per track.
- XML encoded session/project description files (SDI).
- Point-and-click, multi-select, drag-and-drop interaction
(drag, move, drop, cut, copy, paste, paste-repeat, delete, split, merge).
- Unlimited undo/redo.
- Built-in mixer and monitor controls.
- Built-in connection patchbay control and persistence
(a-la QjackCtl).
- LADSPA, DSSI, native VST and LV2 plug-ins support.
- Unlimited number of plug-ins per track or bus.
- Plug-in presets, programs and chunk/configurations support.
- Unlimited audio effect send/return inserts per track or bus.
- Loop-recording/takes.
- Audio/MIDI clip fade-in/out (linear, quadratic, cubic).
- Audio/MIDI clip gain/volume, normalize, export.
- Audio/MIDI track and plugin parameter automation (dynamic curves,
sample&hold, linear and spline modes).
- Audio clip time-stretching (WSOLA-like or via librubberband),
pitch-shifting (via librubberband [9]) and seamless sample-rate
conversion (via libsamplerate).
- Audio/MIDI track export (mix-down, merge).
- Audio/MIDI metronome bar/beat clicks.
- Unlimited tempo/time-signature map.
- Unlimited location/bar markers.
- MIDI clip editor (matrix/piano roll).
- MIDI instrument definitions (a-la Cakewalk(tm) (*.ins));
SoundFont (*.sf2) and MIDI Names XML (*.midnam) files also supported..
- MIDI controller mapping/learn/assignment (mixer and plug-in parameters).
- MIDI system exclusive (SysEx) setups.
- JACK transport sync master/slave.
- JACK session support.
- NSM (Non Session Management) support.
- MMC control surface enabled.
- MIDI Song Position cueing support.
- Configurable keyboard shortcuts.




Changelog:

O.6.6 2015-03-29 Lazy Tachyon Beta

- MIDI clip record/reopen to/from SMF format 0 has been fixed.
- LV2 and VST plugins GUI editor widget position is preserved across hide/show cycles.
- Added application description as freedesktop.org's [url=http://people.freedesktop.org/~hughsient/appdata/]AppData[/url].
- Added a "Don't ask this again" prompt option to zip/archive extrated directory removal/replace warning messages.
- MIDI clip editor (aka. piano-roll) gets lingering notes properly shown while on record/overdubbing.
- Current highlighted client/port connections are now drawn with thicker connector lines.
- Fixing segfaults due to QClipboard::mimeData() returning an invalid null pointer while on Qt5 and Weston.
- Return of an old hack/fix for some native VST plugins with GUI editor, on whether to skip the explicit shared library unloading on close and thus avoid some mysterious crashes on session and/or application exit.
- Force reset of plugin selection list when any of the plugin search paths change (in View/Options.../Plugins/Paths).
- Recursive VST plugin search is now in effect for inventory and discovery on path sub-directories (VST only).
- Non-dummy scannig for regular VST, non-shell plugins, were doomed to infinite-loop freezes on discovery, now fixed.


O.6.5 2015-01-30 Fermion Ray Beta

- Connections lines now drawn with anti-aliasing; connections splitter handles width is now reduced; the MIDI connections splitter pane sizes are now saved and restored properly.
- Extended multi-selection is now featured on the track-list (main left-pane), primarily allowing for group mute/solo (and monitor) switching.
- Track-list (left pane) header column widths are now saved and made persistent across application power cycle (double-click reverts to the old original default).
- Minor fixes on the MIDI clip event list editor, also making sure the current event is visible on the piano-roll view.
- As long to prevent asynchronous mistakes to JACK transport state changes, an internal slack-delay is now introduced after self-initiated transport commands (eg. start/stop).
- The MIDI clip editor (aka. piano-roll) was missing to clear or reset the current selection when no shift/ctrl keyboard modifier is in effect.
- VST-shell sub-plugins are now supported (as suggested by abique aka. Alexandre Bique, thanks).
- MIDI clip record/overdubbing is now possible (Clip/Record on the main menu or File/Record from the MIDI clip editor.
- Make sure some audio sample file encodings (eg. old Ogg Vorbis) does not head-start on audio peak generation.

Hello. I've tried to compile from svn revision 1808 with Qt-4.7.1 and it fails.

.obj/qtractorMainForm.o: In function `qtractorMainForm::qtractorMainForm(QWidget*, QFlags<Qt::WindowType>)':

this is gentoo right? i've got a few reports re.libqt4 builds on gentoo to have this QGtkStyle meta-declaration missing...

try adding the following after line 118 of src/qtractorMainForm.cpp:

#undef QT_NO_STYLE_GTK

the result should look like this:
...
118: #if defined(Q_WS_X11) && QT_VERSION >= 0x040600
119: #undef QT_NO_STYLE_GTK
120: #include <QGtkStyle>
121: #endif
...
then, make again.

Sorry, but that didn't work it out with revision 1817, for previous revisions, too. *sigh*
I have also tried to merge qtractor-0.4.7 but that would downgrade Qt to 4.7.0. Are you running Qt-4.7.1, too?

i am sorry. but the above fix has been already confirmed by someone else.

i wonder whether you have all the necessary Qt4 modules installed.


ps. and yes, i've tried on Qt4.7.0, however as said, this issue only seems to occur on gentoo, which i am no connoisseur :)

Take it as partially solved ;)
qgtkstyle is a part of qt-gui, even shipped with gentoo by default.

$ locate -i qgtkstyle
/usr/include/qt4/Qt/qgtkstyle.h
/usr/include/qt4/QtGui/QGtkStyle
/usr/include/qt4/QtGui/qgtkstyle.h

What should i search for?

Done it the brutal way:

cd ~/src/qtractor-svn
rm -fr *
svn up
make -f Makefile.svn
./configure
make -j3
sudo make -j3 install

Works like a charm!

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
