So it's summer, they say.

White bright and light pastel colors sparkling on every corner and turn. 
Cheesy and silly season, they say. Alas, southerners don't apply. Sorry 
about that. Of course I mean the hemisphere, obviously.

For whom it might concern, all anxiety has come to an end.

Indeed.

It all relates back to this last May 3, when a not-so-formal meeting 
(aka. workshop) took place while during LAC2014 at ZKM-Karlsruhe, where 
some pertinent and undeniable requests were dodged and framed to a 
"soonish" implementation. And guess what?

Yup, the "soonish" are no more, or so I think.

   Qtractor 0.6.2 (boson walk beta) is out!

Perhaps an additional word is due though, about the riddling code-names 
that are branding the post-TYOQA beta releases. They have no personal 
nor logical sense, I assure you. Perfectly arbitrary now. Everything in 
life and the universe is way more unconventional than just a name.

Without further assay.

Qtractor is an audio/MIDI multi-track sequencer application written in 
C++ with the Qt4 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.

Release highlights:
* Plugins activation MIDI controller / automation (NEW)
* LV2 UI Idle and Show (>= Qt5) interface support (NEW)
* Discrete editing of automation curve node velues (NEW)
* Missing audio/MIDI files and plugins warning message (NEW)
* MIDI note drawing on tempo-map changes (FIX)
* Automation curves re-adjusted to tempo-map changes (FIX)

Change-log:
- Prevent linear and spline automation curve modes for all integer 
valued subjects. Also, make sure those values are rounded to the nearest 
integer away from zero.
- Fixed save of LV2 Presets for plugins with state files.
- A man page has beed added (making up Gürkan Sengün's work on debian, 
thanks).
- When moving plugins by eg. drag-and-dropping across tracks, automation 
curves were being left behind, maybe leading to unpredictable mistaken 
behavior. Hopefully, not anymore.
- Translations install directory change.
- Automation curves are now automatically re-adjusted to tempo map node 
changes (after a ticket by Holger Marzen, thanks).
- Audio/MIDI files or plugins found missing on session load are now 
subject for an explicit modal warning message and prompt for an 
immediate session backup salvage.
- Changing instrument plugin programs is now an undo/redo-able command 
operation, especially for DSSI but also for plugins that come with the 
LV2 Programs interface extension support 
(http://kxstudio.sourceforge.net/ns/lv2ext/programs).
- Drawing, selecting and/or resizing of MIDI note events that extend 
across tempo/time-signature changes is now made a bit more correctly 
over the MIDI clip editor (aka. piano-roll), especially regarding to 
current snap-to-beat setting (after an outstanding ticket by yubatake, 
thanks).
- Once again, audio frame/MIDI time drift correction has been slightly 
refactored to improve MIDI input monitor and timing.
- Discrete automation curve node values may now be edited via a 
numerical entry floating spin-box on double-click (as yet another 
request by AutoStatic aka. Jeremy Jongepier, thanks).
- Pressing shift/ctrl keyboard modifiers while double-clicking on a 
plugin list entry now briefly reverses the current 
View/Options.../Plugins/Editor/Open plugin's editor (GUI) by default 
option preference.
- Fixed an old crash lurker when switching output buses that implied a 
change on the number of audio channels, while on tracks that have 
(auto-)monitor turned on and at least one active plugin in chain (yet 
another ticket by AutoStatic aka. Jeremy Jongepier, thanks).
- MIDI Controller assignment (aka MIDI learn) and/or automation of 
plugins (de)activation state has been added (as requested by AutoStatic 
aka. Jeremy Jongepier, thanks).
- LV2 UI Idle and Show interfaces support added.
- Allow the build system to include an user specified LDFLAGS (patch by 
Alessio Treglia aka. quadrispro, thanks).
