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(2), VST3 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/New Session Management) support.
- MMC control surface enabled.
- MIDI Clock, Song Position Pointer (SPP) support.
- Configurable PC-keyboard and MIDI controller shortcuts.
Last changelog:

0.9.19 2020-12-20 26 days ago

- Session directory auto-name option added to the session properties dialog, as convenience.
- Loading and saving a LV2 plugin's state has been vastly improved. IMPORTANT CAVEAT: From this moment onwards, when loading any newer saved sessions into older versions of the program, all LV2 plugins won't get their state restored correctly.
- Track colors saturation introduced as yet another eye-candy option (cf. View/Options.../Display/Track color saturation)
- Fixed VST3 number of channels query/report.
- Fixed immediate crash when loading untitled or unnamed Instrument Definitions files (*.ins): base file-name is now taken as default instrument definition name or title.
- Tempo (BPM) entry may now be specified with arbitrary precision, to at most 3 decimal positions in fractional part, while integer whole values are displayed with no decimal point.
- Added option to keep MIDI clip editor windows (aka. piano-roll) always on top of the main window (cf. View/Options.../General/Keep editor windows always on top).
- MIDI clip editor status-bar labels are not stretched to whole text size anymore, most specially for the current file complete path.

hello man could you please specify in the product settings packagetype for appimage (set it to appimage), so that it appears in the appimagehub subcategory of pling.com. That way people looking for appimages could easly find them there. If you can do it for all 5 products you have here it would be much appreciated

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.

all respective dependencies are also available from (my) OBS repository (http://download.opensuse.org/repositories/home:/rncbc)

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.
