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.

It was time that a cool audio sequencing application was developed !
To be honest I haven't tried it yet, but I'm following with pleasure your constant improvements and efforts. I am a hard user of Cubase SX and I would really love to definitely switch to Linux also for that purpose, and achieve 0 latency recording and mastering.
The key thing for these applications is a serious VST instruments support. Once you get it you're done ! Have you planned it at all for the future ?
Again, many congratulations !

Regarding VST support: it is in deed in the workings. On the workbench there's DSSI and native VSTi plug-in support. That's right, with DSSI-VST you will reach windows VSTs through wine, and with native VSTs you should have an open road to native linux VSTs (yes, there are some few out there;)
it's coming, but I can't really tell when it will be ready ;)

In qtractor, exporting is the process to produce a mix-down of one or several tracks resulting into a brand new media file; it's like rendering audio _or_ MIDI into a new media file (either audio file _or_ SMF, not both).
OTOH, regarding the "project" concept, IIUC, is here known and called as "session", as the program's "working session". This working session is rightly stored as a XML encoded file (.qtr file ext/suffix) as being the complete description of the arrangement, including all audio/MIDI tracks, clips, buses and the whole setup made while operating the application program. Have this noted, that a session file does NOT ever store or include any kind of media contents, rather just the file path references where it might get found in the local file system.

Please, edit src/qtractorMainForm.cpp and change line 232, or around where it reads:
#if QT_VERSION >= x040300
m_pTempoSpinBox->setKeyboardTracking(false);
#endif
change it to:
#if QT_VERSION >= 0x040301
m_pTempoSpinBox->setKeyboardTracking(false);
#endif
or, just get rid of the #if/endif block if you like; it's only usable on >= Qt4.3.1 anyway ;)

As quick workaround you may edit the offending file, src/qtractorFileListView.cpp, line 594, and where you read:
pGroupItem->setExpanded(!pGroupItem->isExpanded());
substitute it exactly by:
setItemExpanded(pGroupItem, !isItemExpanded(pGroupItem));

But you can bounce your session into a new track. Just add a new empty audio track, connect the outputs of all other tracks to the input of this new one, arm it for recording and start record+play. There you go, you'll be recording (in real time, though) what would be the result of a future export operation.
Depending on your current audio capture option (see menu View/Options.../Audio/Capture) the captured file might be in the Ogg Vorbis format.
There is no current nor future plans for MP3 encoding support, so that's a definite NO for the last half of your question. Remember that MP3 is only supported on playback. It has nasty technical drawbacks and its not a very wise choice for audio recording altogether. Choose OGG instead, or better yet, FLAC. That's only my opinion, of course.
Cheers.

Make sure the JACK audio server (jackd) and/or
the ALSA Sequencer kernel module (snd-seq-midi)
are up and running and then restart the session."
I install all librearies (also jackd) but playlist not run :(
Report
rncbc

But, if its the very first time you are dealing with jackd, please be prepared that things might get harsh before you have a full top-notch audio system under you rig :)
In summary you'll have to make sure you, as a user, have realtime scheduler privileges.
Check your /etc/security/limits.conf file for some entries like this ones:
@audio - rtprio 90
@audio - nice -10
@audio - memlock 4000000
Then you have to add yourself (the username) part of the audio group. For the fast track, and most promiscuous too, just replace '@audio' by '*' in the above lines.
After those modifications, which should be carried on by root anyway, you must relogin as your regular user and then start jackd. If you're lacking QjackCtl GUI friendliness, you can start it from the command line, like this:
$ jackd -R -dalsa -dhw:0 -r44100 -p1024 -n2
Another issue could be that the ALSA sequencer kernel module might not be currently loaded. You can get the head-start by doing it as root:
# modprobe snd-seq-midi
From now on you can hit qtractor and start playing around. I hope you get the picture all right.
Cheers.

OK. Let's try another way.
First of all make certain you have all Qt4 devel tools installed. That is qmake, moc and uic. As said, probably those are renamed with the -qt4 suffix. You have to cheack that out. Let's assume qmake has been renamed to qmake-qt4.
Second, make sure you have all the dependencies also in place, that are libjack, libasound (alsa), libsndfile, ladspa, libvorbis(enc, file) and libmad, specially the devel ones.
Third, on the qtractor source tree you may find the win32 sub-directory. Move in there and just type `qmake-qt4 && make`.
Hopefully it will build fine, and you'll end there with the `qtractor` executable ready to run and play.
Enjoy.

You just need to adjust debians "alternatives" system (man update-alternatives) or, if you still compile against qt3 more often, set some environment variables in the shell, you use to build the qt4 program:
export LD_LIBRARY_PATH=/usr/lib:$LD_LIBRARY_PATH
export PATH=/usr/share/qt4/bin:$PATH
export QTDIR=/usr/share/qt4

Ah,... on so-called "sane" distros (aka not "braindead broken", sorry for the pun) qt3 and qt4 do coexist. And that's what I'm used to. Setting the build environment for each one has been just a matter of PATH tweaking, if one at all. Not a debianese mess, even if its FHS compliant or what. Sorry again :)
Particular problem with Qt deployment on debian seems to be the way that Qt programs, headers, libraries and what not, are kept splintered across the file system. On "sane but FHS broken" distros, all of the Qt tree is usually kept under one single point. Just a minor cost of a particular distro non-standard design ;)
Of course, I should know better that debian guys/gals always know what they're doing :)
Sorry for the twisted humor, and most of all, just plain debian ignorance ;)
Now, back to reality, does it help in any way having this one for a start?
$ ./configure --with-qt=/usr/share/qt4
Just trying... but I'm afraid, due to the way my reasoning works, it should also fail on debian FHS splintering :P
Cheers.
