Qtractor (Linux) updated to v0.4.6                28th May 2010

Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt4 framework [1].

Target platform is Linux, where the Jack Audio Connection Kit (JACK) for audio [2] and the Advanced Linux Sound Architecture (ALSA) for MIDI [3] are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

What is new:

  • Introducing a non-painting edit sub-mode on the MIDI clip editor's piano-roll (see Edit/Select Mode/Edit Draw menu).
  • The MIDI clip editor (aka piano-roll) is now a lot more quiet about saving its own dirty content, delegating all salvage questions to main session control.
  • Don't show session restart message box when changing JACK transport mode option anymore.
  • Dedicated MIDI control bus switching fixed. Was closing the wrong bus eventually and crashing the whole show with it (fixes bug #2989590).
  • MIDI bank/program backout has been corrected on MIDI track properties dialog rejection (ie. user cancellation).
  • MIDI bank select method has been corrected for tracks with no instrument defined (probably fixing bug #2987071).
  • LV2 UI Instance and Data Access extension support added; reduce LV2 external UI parameter value update flickering.
  • JACK session infrastructure support. (EXPERIMENTAL)
  • Initial widget geometry and visibility persistence logic has been slightly revised as much to avoid crash failures due to wrong main widget hidden state.
  • Initial mixer widget extents are now set reasonably larger.
  • General source tree layout and build configuration change.
  • Ever since smooth-ramping introduction that having at least one input-only buses were causing immediate playback crashes, now hopefully fixed.
  • Refactored for common engine client nomenclature, primarily provided by JACK, then secondarily passed to ALSA Sequencer, getting rid of the JackUseExactName requirement and lifting the unique/single instance restriction in the process.
  • Current JACK Transport, MMC Device, and MIDI Song Position pointer (SPP) control modes are now saved/loaded as part of session option properties.
  • MIDI clip editor's context menu crash on Qt >= 4.6 has been fixed (resolving bug #2972603).
  • An ancient double-free corruption has been finally fixed at the audio/MIDI bus connection persistence logic.
  • Improved visibility of track state buttons text (R, M, S) when turned on dark colored themes.
  • LV2 Save/Restore extension support kicks off.
  • MIDI engine read-ahead period has been shortened to half than it was since inception--now it's a 500msec cycle.
  • MIDI clip editor event list gets its due inline editing, for time, note, value/velocity and duration columns, just one double-click away over the target cell ;)
  • Add-plugin selection dialog position and extent are now remembered across invocations and application sessions (tipping by Frank Neumann).
  • MIDI clip time-stretching is now made available through the same gestures as audio ones, by just shift+dragging either of the clip edges.
  • Drag-and-copying plug-in instances (cloning) is now fixed with regard to parameter value replication.
  • MIDI clip editor snap-per-beat setting is now independent from main multi-track view; File/Save As... dialog fixed; the current event selection is now kept floating as long as it's possible after editing command actions; finally, edit mode has been extended to free-hand event drawing, chalking off (piano roll) draw mode from the TODO list.
  • Swing-quantize has finally made its overdue debut as an additional MIDI clip editor tool (see Tools/Quantize...).
  • Almost since its inception, audio inserts were injecting garbage random noise when not being activated, now fixed.
  • Dedicated audio output ports for MIDI track plugins, now have their connection persistence back in business due on session load.
