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.
It all relates back to this last May 3, when a not-so-formal meeting
(aka. workshop) took place while during LAC2014@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.
* 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)

- 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,
- 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
- 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,
- 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
- 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).
Enjoy && have (lots of) fun.
