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:

0.9.17 2020-09-15 An End-of-Summer'20 Release 9 days ago

- Early fixing to build for Qt >= 6.0.0 and the c++17 standard.
- Fixed crash when changing an auto-monitored audio track's number of channels due on switching its audio output bus.
- Avoid a complete track re-open when changing properties, unless either input or output buses are changed.
- Fixed custom track icon selection when none is currently set.

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.

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.

0.9.17 2020-09-15 An End-of-Summer'20 Release 9 days ago

- Early fixing to build for Qt >= 6.0.0 and the c++17 standard.
- Fixed crash when changing an auto-monitored audio track's number of channels due on switching its audio output bus.
- Avoid a complete track re-open when changing properties, unless either input or output buses are changed.
- Fixed custom track icon selection when none is currently set.

0.9.16 2020-08-07 A Summer'20 Release 1 month ago

- Experimental / High resolution plugin automation (14-bit) options is now also removed from View > Options... > Plugins dialog.
- Audio Clip / Export... now takes into account custom fixed gain property (shamefully missing for the whole last decade to date).
- Finally indulged on dummy LV2 plug-in CVPort support, just to avoid certain immediate and sudden crashes when inserting those kind of 'non-functional' plugins accidentally.
- Bring the Track Export dialog down to Clip Merge/Export as well, for optional file type and format selection.
- When enabled, do auto-save upon adding or inserting a new plugin.
- Make sure LV2 plug-in UI GTK2 and X11 native support is selected first by default on top to libsuil.
- Both out-of-process plugin inventory scan and LV2 Dynamic manifest options have been removed from View > Options... > Plugins dialog.
- Fixed deprecated stuff on an early preparation for Qt6.

0.9.15 2020-06-27 An Early-Summer'20 Release 2 months ago

- Fixed MIDI tracks export that were missing the end-of-export tail parameter and bailing out always with default SMF format anyway.
- Fixed VST3 component/controller inter-connection.
- LV2 Atom/Port-event host notification support has been retouched, but still unofficial though.
- Fixed VST3 audio-processor initialization/activation when a plugin has no inputs or outputs present.
- Let main window pseudo-asynchronous stabilization re. menus, tools and status bars, just faster and immediate.
- Fixed MIDI track monitor re-instantiation and reset.
