Can't hold it anymore... :)
Since its primordial presentation on the LAC2007@email-addr-hidden-Berlin, almost one
year ago, I guess it's finally ready for an official public release. So
here it goes.
Qtractor development has been going stealthy but has been matured
nicely. Still alpha however, but quite practical nevertheless. Or so I
believe. Yes, things might get bumpy, faster or slower though, we never
know in advance. And quite frankly I don't give a damn whether how it
might progress from now. But it will progress, that's what I shall write
here engraved ;) Trust me.
Qtractor has been my hobby, kind of personal purpose in life and should
stay in that status for quite some time. You probably have noticed
there's too many buts in this discourse of mine, and guess what? there
follows some more for your pleasant delight.
As long as all its ecosystem bears sustainability; no hidden thoughts;
it's all about JACK, ALSA and ultimately Linux that I'm counting on.
I've made myself ascertain: I will make no effort, whatsoever, in doing
any kind of cross-platform dance. Although it seem feasible, just don't
expect that kind of behavior from this side of the party. I'm not
obliged to. I'm happy now with what I've got and to what has been
achieve in this recent years. Linux is my home and you better get it
right, I'm comfortable with it.
It could be seen as my "masterpiece", although you might find I'm no
master at all. Take it as my pet project, because, in fact, it is just
that, really! If you feel minimally interested, you might want to come
along and be welcome. I'll cherish you, that's what friends are. Willing
to share the journey, and follow the turns. No commitments, just fun!
Now, after that bunch of BS, let's get the facts straight, right behind
the thoughts:
Qtractor 0.1.0 (frivolous debutante) has been released!
Good grief. As always, everyone is welcome to grab the source and also
some selected binary packages, available from the official project site:
http://qtractor.sourceforge.net
http://sourceforge.net/projects/qtractor
Direct link for the source tarball download:
http://downloads.sourceforge.net/qtractor/qtractor-0.1.0.tar.gz
For the clueless, a refurbished whitepaper is also available:
http://downloads.sourceforge.net/qtractor/qtractor-0.1.0-whitepaper.pdf
Also of note is this (strong) invitation to follow my personal blurbs,
right from the upstream blog and forum site:
Here follows the change-log. as recorded since that one last previous
pre-release, which was tagged as 0.0.9.778 (adolescence prime) on the
late year:
- Audio clip time-stretching makes its debut, with code adapted and
refactored from the SoundTouch library, under the (L)GPL umbrella.
- New "Options.../Audio/Playback/Quick seek time-stretching" global
option, providing a quick seek mode (hierarchical search) while
doing all audio buffer time-stretching.
- Changing session tempo will automatically apply the corresponding
time-stretch percent factor to all in-place audio clips. Audio
clip dialog also includes a new time-stretch property setting.
- Tempo changes are now affecting clip offsets correctly, keeping
the clip offset constant in time units (ticks), as are clip start
and length properties already.
- Mixer splitter sizes are now properly saved/restored when hidden.
- Extended multi-selection is now featured on the files widget; all
drag and drop functionality has been almost completely rewritten.
- SSE optimization is now enabled where available (via configure).
- Options for having separate dedicated ports for the audition/pre-
listening player output, audio metronome output, MIDI control
input/output and MIDI metronome output, are now in place.
- A brand new subtle option sneaks in, affecting the drag-and-drop
of the main track-view: View/Options.../Drop multiple audio files
into the same track, whether to drop multiple external files into
new or existing track as concatenated audio clips.
- The audio metronome makes its debut as an alternative to the MIDI
existing one; parameters include bar and beat audio sample files,
accessible from the View/Options.../Audio/Metronome dialog.
- Files widget action refactorization; the files context menu gets
its due item icons and a new menu item for direct audio player
accessibility.
- MIDI time resolution changes (ppqn, ticks per beat) now tries to
keep all session MIDI clip times unchanged as far as possible.
- MIDI channel volume and panning control change events, CC#7 and
CC#10 respectively, are now rendered unfiltered on playback .
- First rendition of the long due implementation of an audition or
pre-listening audio player is now in place; the files window got
this new play/stop control button on its lower-right corner.
- Actual instrument definition note (keys) and controller names are
now in effect on the MIDI editor, whenever applicable.
- Fixed instrument bank selection method, "Bank MSB" (2), which was
broken enough to never send the correct bank number.
- Mouse-wheel horizontal scrolling is now accessible on every view,
while pressing a modifier key (Shift or Ctrl).
- New auto-backward transport option: when enabled the playhead will
be reset backward automatically whenever transport stops playing.
- A suicide-crash has been fixed while invoking the bus dialog from
the respective mixer bus strip context menu.
- Master (default) buses are always set to Duplex mode, being now
an enforced update policy while on the Buses dialog.
- A stupid lockup bug (infinite loop) was spotted on the track bus
assignment method and squashed (thanks, lexridge).
- New keyboard shortcuts for toggling the Connections tool (F8) and
the mighty Mixer tool (F9) windows.
- Avoid showing a context menu while right-clicking on time rulers.
- Audio clip waveform drawing gets additional closing points.
- It is now possible to change the length/size of a clip by dragging
its left or right edges, while in the main track-view. Shift+drag
will also time-stretch to the resulting audio clip length.
- Another off-by-one mistake was corrected, which was causing audio
clips to go out-of-sync on loop turnover boundary; also changed
the loop turnaround strategy, now honoring already cached periods.
- A race-condition has been mitigated in the audio-buffer thread,
that was exposed and lead to sudden application freezing upon
changing some composite audio clip commands.
- Take absolute audio peak values only, making peak files a little
bit shorter and hopefully faster to load and draw as waveforms.
Ah, never's too late to wish you all a Happy New Year!
Cheers && Enjoy
