Thank you

Hey man you did a really good job with Qtractor !
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 !

Thanks, and please, do have a try. It will much appreciated.

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 ;)

hi,
great app !
i would like to save the project but not in a media file, can we ? like the audacity .aup

ok, i found it.
maybe the 2 windows when you want to save are unusual, for me

Maybe we're confusing disparate concepts; probably it needs some clarification.

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.

HTH

Cheers && Happy New Year

but,when i go to make i get this error...i tried the cd/ win32 qmake && make but i get the same thing...any thoughts?

That is a light Qt 4.3 version mismatch somewhere (nb. you're dealing with a Qt4 version suited for KDE4, maybe Qt4.3.0, which I have skipped).

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 ;)

Hi.
Apparently Kubuntu only provides the JACK application and not the devel-libs. Or am I wrong? Anybody who can point me to the .debs for "jackd-devel"?

as i used to say, i'm no debian expert, but i do remember that the packages name to look for ought to be libjack-dev, libjack0-dev or even libjack0.100.0-dev on some older dabianese package naming convention.

guess its in ubuntu's universe repository but who am i to tell that for sure :)

cheers.

libjack0.100.0-dev did the trick:-)

Oops. You're on Qt 4.1, the offending code is already over Qt 4.2, sorry.

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));

or you can wait and I will fix that on CVS in a few minutes :)

Cheers.

I guess you've updated from CVS alright, but somehow you probably forgot to regenerate the autoconf stuff.

Remember, when checking out from CVS you must do the `make -f Makefile.cvs` all over gain.

Seeya.

It's working. Thank's. :o)

And for export into .ogg or .mp3 my project?

Export is not yet featured. Keep in mind this is still alpha stage on development.

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.

"The audio/MIDI engine could not be started.

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 :(

You have to start jackd sound server in first place. Make it a try with yours truelly QjackCtl :)

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.

oh come on - it's not the right place to post bug reports here

I've found that my autoconf/qmake wrapping always clashes on debian. On debian based distros (e.g. ubuntu), it has come to my knowledge, deployment of the Qt devel tools (qmake, uic, moc) is not as usual and somehow the debianese folks decided to rename the executables to somethink like qmake-qt4, moc-qt4, uic-qt4 and what not. This is braindead broken IMO, and it surely is non standard. Why on earch would one rename the original executable files? Betas me.

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.

Hi, it's not "braindead broken" it's just a way of having qt3 and qt4 coexist in the FHS.

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
export QT_PLUGIN_PATH=/usr/share/qt4/plugins
unset XDG_CONFIG_DIRS
unset XDG_DATA_DIRS
