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 [1].
- Uses JACK [2] for audio and ALSA [3] sequencer for MIDI
as multimedia infrastructures.
- Traditional multi-track tape recorder control paradigm.
- Audio file formats support: OGG (via libvorbis [6]),
MP3 (via libmad [7], playback only), WAV, FLAC, AIFF
and many, many more (via libsndfile [4]).
- 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 [16]).
- LADSPA [5], DSSI [11], native VST [12] and LV2 [13] 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 [9]),
pitch-shifting (via librubberband [9]) and seamless sample-rate
conversion (via libsamplerate [8]).
- 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) [18]);
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 [15].
- MMC control surface enabled.
- MIDI Clock, Song Position Pointer (SPP) support.
- Configurable PC-keyboard and MIDI controller shortcuts.
Last changelog:

0.9.2 2018-09-09 Summer'18 release 15 days ago

- AppData/AppStream metadata is now settled under an all permisssive license (FSFAP); also updated to be the most compliant with latest freedesktop.org specification and recommendation.
- Fix build for Qt >= 5.11.0 (by David Geiger, thanks); also for some g++ >= 8.1.1 warnings and quietness.

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!

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.

0.9.2 2018-09-09 Summer'18 release 15 days ago

- AppData/AppStream metadata is now settled under an all permisssive license (FSFAP); also updated to be the most compliant with latest freedesktop.org specification and recommendation.
- Fix build for Qt >= 5.11.0 (by David Geiger, thanks); also for some g++ >= 8.1.1 warnings and quietness.

0.9.1 2018-05-29 Pre-LAC2018 Release Frenzy 3 months ago

- Displaying MIDI note(on) events as diamonds instead of simple rectangles (aka. Drum Mode) is now being introduced as an optional MIDI track property (Drums) and as a MIDI clip editor (piano-roll) visual option (cf. View/Drum Mode).
- Extended multi-selection is now supported on all the Connections client/port lists, allowing for multiple (dis)connections at once.
- Added LV2 UI sample-rate option support.
- Always reset all internal dedicated MIDI controllers, eg. MIDI track volume (CC#7) and panning (CC#10), on Transport/Panic and after rendering export to aud1io (ie. Track/Export Tracks/Audio...) as needed to reset MIDI instrument plugins to nominal session state.
- Fix, detect and preserve MIDI Bank-select method across MIDI track/clips editing operations.
- Fixed MIDI track and clip note min/max display range while recording and also when duplicating tracks.
- Added "All files (*.*)" filter to every file requestor dialog, wherever missing.
- The tiny zoom-magnifier icons have been revamped.

0.9.0 2018-03-22 Early Spring'18 Beta 6 months ago

- New View/Options.../Plugins/Experimental/Show plugins on track list/left pane option is in effect on tracks that are tall enough in height for their plugins list to fit on the Bus column.
- Fixed a day-zero bug over the MIDI Insert (Send/Return) pseudo-plugin, which was duplicating MIDI events onto the next LV2 plugin in chain, causing strange hanging notes, mutes, retriggerings and what not.
- MIDI track and clip note min/max range display now fixed.
- MIDI Program Change events (PC) now have their proper program number as parameter, instead of value, on the internal MIDI event representation.
- Merging MIDI clips while on SMF Format 0 has been fixed: was merging always onto the same MIDI channel (2), most often the wrong one, resulting in an empty or blank clip.
- When importing from standard MIDI files (SMF), set track names from Mtrk TRACKNAME meta-events instead of filename.
- Avoid asking to save as to existing or just newly created clip file-names, whenever possible.
- Disable singleton/unique application instance setup logic when the display server platform is not X11.
- Whether to use native file browser/requester dialogs is now an effective option when launching under NSM session management (was once disabled initially).
- Content files are now saved as symlinks when saving to JACK and/or NSM session directories/folders.
- Trying to get CC14 MSB+LSB (course+fine) running status on, no matter whether each pairing event are under 200ms apart.
- Possible VST plug-in GUI reparenting hack/fix on Qt5/Xcb.
