Season greetings. 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 and MIDI.

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 tell me.

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:

qtractor-0.1.2-user-manual.pdf

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 note events.
• 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 effects processing.
• 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 (http://www.anticore.org/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
