Description:

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.

Features:

- Multi-track audio and MIDI sequencing and recording.
- Developed on the Qt C++ application and UI framework.
- 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, including native VST FXB/FXP file support.
- Unlimited audio/MIDI effect send/return inserts per track or bus.
- Loop-recording/takes.
- Audio/MIDI clip fade-in/out, cross-fade (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) and seamless sample-rate conversion (via libsamplerate).
- Audio/MIDI track export (mix-down, render, merge, freeze).
- 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 Clock, Song Position Pointer (SPP) support.
- Configurable PC-keyboard and MIDI controller shortcuts.
Last changelog:

0.9.7 2019-04-16 Spring-Break'19 Release. 1 month ago

- Re-defined all main application UNIX signal handling.
- Fixed possible crash in drawing clips while rare loop-recording/takes situations.
- Main window stabilizing is now kind of asynchronous re. menus, tools and status bars.
- MIDI Controller's Latch mode attribute on tracks and plugins are now properly saved/loaded as meant to be.

This and recent qjackctl are looking for libjack0. This is an older version and not compatible with recent distro upgrades of Debian, etc.

I can compile it.

Debs will not install correctly. Dependencies listed are incorrect/obsolete:
qtractor : Depends: libjack0 but it is not going to be installed
Depends: liblilv-0 but it is not installable

Not the point.
The distro's repositories have these libs with slightly different names so a package for the distro should site them: For example, Debian has libserd-0-0 instead of libserd-0.

Qtractor is a joy to use, reminds me a lot of emagic logic without the objects layers.
This is a very usable program and does the job without any hiccups!

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!

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

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.

Thanks. Awe! Those GB colors are already mysteriously similar to Qtractor's. I wonder why should one make it even more of the same with icons and stuff :) from where I stand, ppl would start to think it's a GB clone, when it never was meant like that. But I see your point.

Cheers.

- MIDI Controller's Latch mode attribute on tracks and plugins are now properly saved/loaded as meant to be.

0.9.6 2019-03-20 Pre-LAC2019 Release Frenzy. 2 months ago

- Fixed LV2 UI Touch feature/interface implementation.
- Plugin latency/delay compensation is now introduced as an option to tracks only (cf. Track/Properties.../Latency compensation).
- Refactored all singleton/unique application instance setup logic away from X11/Xcb hackery.
- A bit lesser of a naive file-name numbering is now in place to avoid as much as possible, the piling up of internal curve/automation files when saving existing sessions.
- Maybe just informational but the original MIDI file format is now correctly reported across ref-counted linked MIDI clips.

0.9.5 2019-02-14 A Valentines'19 Hotfix release 3 months ago

- HiDPI display screen support (Qt >= 5.6)
- Fixed for DSSI plug-ins (eg. fluidsynth-dssi) loss of configuration state: clear internal config/state keys on release virtual method.
- Fixed for NSM (and JACK) sessions not saving the correct file references/symlinks of clips that are recorded or created during the initial and scratch session.
