As (almost) everybody knows already, or ought to, Qtractor is an
Audio/MIDI multi-track sequencer application, written in C++ on the Qt4
framework and Linux is about its native platform. Thus, JACK and ALSA
are the main infrastructures that fit to purpose, respectively for audio
Also a known fact is that this is nothing more than my pet, hobby,
spare-time-burner, whatever project, but... it's actually my own dogfood
where digital music making and (re)creation matters. Yep. I still have
this sublime hope to make it evolve as a fairly featured Desktop
Audio/MIDI Workstation, one special and dedicated to the personal
homestudio. As joked many times before, it's perfectly tagged for the
techno-boy bedroom home-studio, but techno-girls can also apply ;). You
Qtractor 0.1.2 (frantic dame) is out!
As obvious as in any respectable easter egg ;)
This time, some important fixes have sneaked in and other are surely
popping and will be lurking out. Main ones go down like this:
* You can finally create new clips from scratch.
* Track record monitoring with audio effects applied.
* New Track/View menu items, all shortcut configurable.
* Overlapped clips rendering hopefully fixed.
* Improved MIDI editor selection.
* New clip-split command.
* VST plug-in parameters are now undo/redo-able (mostly).
You can grab the new stuff from the usual project site:

Wait, please take a note: if you ever feel you're having something to
say, a heads-up call or just a direction to point, do not ever hesitate

Now the plain change-log follows, since she was just a futile duchess:
- Session length fixed (yet again) while extend recording; also
improved follow-playhead switching while playback/recording.
- Whitespace sanitization gets leaner for all recorded filenames.
- Run-time SSE optimization detection has been improved while on
configure; additionally, IEEE 32bit float specific optimizations
have also sneaked in.
- SSE optimization is now featured over all audio monitoring, and
most specially on audio bus buffering, lowering the CPU burden a
bit while doing track and bus gain, pan, metering and mix-down.
- Fixed MIDI clip move into new track, preserving the original
channel, bank and program whenever possible.
- Fixed session cursor seeking, specially regarding overlapped
clips, once gain.
- The MIDI editor gets new menu access to current MIDI clip track
(see File/Track/Inputs, Outputs, Properties); selection of MIDI
events has also been improved, specially regarding overlapped
- Clip split command enters the stage (see Edit/Clip/Split) about
splitting the current (selected) clip at the current playhead
position (red cursor line).
- Creating new clips from scratch is now finally permitted (see
Edit/Clip/New...); additionally, the clip properties dialog is
now also allowing for changing the filename (and track/channel
as special to MIDI clips).
- Record armed tracks are now properly monitored and fed through
their own output audio bus on mix-down, which includes plug-in
- The files widget get alternating coloured rows.
- VST plug-in preset values are now being restored properly;
individual parameter changes are now being queued for the
also convenient undo/redo command pattern.
- Some audio clip buffer-sync tweaks have sneaked in, improving
and fixing the rendering of full-overlapped, integrally cached
and/or offset clips altogether.
- Stuffed one primordial shot on XInitThreads() at the main head,
and let native VST plug-ins start behaving as they should, or
not; this might be in fact problematic and dangerous for people
who won't ever try the JUCE based plugins as from JUCETICE
), due to some broken locking
mechanism in xcb; thanks anyway to mighty kRAkEn/gORe@JUCETICE
for this precious hint and from who knows best.
- True deterministic session length update has due fixed.
- Track menu has new accessible actions:
Track/Inputs - show current track input bus connections;
Track/Outputs - show current track output bus connections;
Track/State/Record - arm current track for recording;
Track/State/Mute - mute current track;
Track/State/Solo - solo current track;
Track/Navigate/First - make current the first track;
Track/Navigate/Previous - make current the previous track;
Track/Navigate/Next - make current the next track;
Track/Navigate/Last - make current the last track;
Track/Move/Top - move current track to top;
Track/Move/Up - move current track up;
Track/Move/Down - move current track down;
Track/Move/Bottom - move current track to bottom;
- View menus have new accessible actions:
View/Zoom/In - horizontal and vertical zoom-in (Ctrl +);
View/Zoom/Out - horizontal and vertical zoom-out (Ctrl -);
View/Zoom/Reset - reset both zoom levels to default;
View/Snap - select current snap-per-beat setting;
- Plug-in forms don't auto-open on session reload anymore.
- Keyboard shortcuts icon item (Help/Shortcuts...) sneaks in.
That's all folks. For the time being... :)
Cheers && Enjoy
