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:

0.8.5 2017-12-04 Autumn'17 Beta 6 days ago

- Audio clip gain and panning properties are now taken into consideration when hash-linking (aka. ref-counting) their back-end buffers.
- New out-of-process plug-in inventory scan and cache option, replacing the old (aka. dummy) VST plug-in scan option and extending its function to all other plug-in types: LADSPA, DSSI and also LV2 (cache only).
- A File System browser and tree-view is finally integrated as a dockable-widget on the main application window (cf. main menu View / Window / File System).</li>
- Drag-and-dropping of session, audio and MIDI files over the main track-list (left pane) is now possible, allowing for yet another quick means to open a new session or add new tracks to the current session.
- MIDI input/capture time-stamping has been fixed as much to avoid missing inbound events, when play-head is near the loop-end point and the loop-start is set below the absolute first half-a-second (<0.5sec).
- LV2 Time/Transport speed information is now set on rolling when in audio export aka freewheeling mode.
- Added *.SF3 to soundfont instrument files filter, on View > Instruments... > Import... file dialog.
- A brand new View/Options.../Display/Meters/Show meters on track list/left pane option has been added.

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.

0.8.4 2017-09-20 End of Summer'17 Beta 2 months ago

- Assigned MIDI Controllers to plug-in's Activate switch are now finally saved and (re)loaded properly across sessions.
- Audio clip panning option property is now being introduced.
- Out-of-process (aka. dummy) VST plug-in inventory scanning now restarts automatically and resumes processing in case of a premature exit/crash; VST plug-in inventory scan/cache persistency is now in place.
- Desktop entry specification file is now finally independent from build/configure template chains.
- Updated target path for freedesktop.org's AppStream metainfo file (formerly AppData).
- Changing the View/Options.../Display/Custom/Style theme takes effect immediately unless it's back to "(default)".
- Slightly slower but better approximation to IEEE 32bit floating point cubic root ie. cbrtf().

0.8.3 2017-06-30 Stickiest Tauon Beta 5 months ago

- Make sure any just recorded clip filename is not reused while over the same track and session. (CRITICAL)
- LV2 Plug-in worker/schedule interface ring-buffer sizes have been increased to 4KB.
- Fixed track-name auto-incremental numbering suffix when modifying any other track property.
- WSOLA vs. (lib)Rubberband time-stretching options are now individualized on a per audio clip basis.
- Long overdue, some brand new and fundamental icons revamp.
- Fixed a tempo-map node add/update/remove rescaling with regard to clip-lengths and automation/curve undo/redo.
- Fixed a potential Activate automation/curve index clash, or aliasing, for any plug-ins that change upstream their parameter count or index order, on sessions saved with the old plug-in versions and vice-versa.
