Ah, the equinox...

Twice a year a cherished planetary alignment checks in on schedule, once again.

The little rock gets another round from its warmy solar furnax, from which were forged. The pale blue dot gets yet another round and to no surprise, another tinier dot gets here around:

Release highlights:

• Revamped mixer (un)dockable panels (NEW)
• Plugin preset selection sub-menu (NEW)
• LV2 Time position/transport event support (NEW)
• Constrained plugin multi-instantiation (FIX)
• Automation curve node resolution (FIX)

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.

nb. Despite the old Qt4 stance, but still recommended, Qtractor does build, runs and does it all on Qt5 for quite some time now. However, the former recommendation prevails as the despicable LV2 plugin GUI X11/embedding support through libSUIL just does NOT work on modern Qt5.

Change-log:

• Make the mouse-wheel to scroll the plugin list views, when not hovering a direct-access parameter slider.
• Mixer widget gets (un)dockable Inputs and Outputs panels, also with their respective title captions.
• Plugin instantiation is now constrained as much to prevent any audio channel output overriding.
• Existing plugin presets may now be selected right(-click) from plugin list context-menu (ticket by Harry van Haaren, thanks).
• So-called "painting" over multiple selected event values, while on the MIDI clip editor view pane below the main piano-roll (eg. note velocities, controller values, etc.) is now split into two similar painting modes, whether the sub-menu Edit/Select Mode/Edit Draw is set on (free-hand) or off (linear).
• Drag-and-copy of plug-in instances across tracks or buses (ie. cloning) now also copies the direct access parameter setting (ticket by Holger Marzen, thanks).
• File/Save As... now prompts and suggests an incremental backup name for existing sessions files.
• Zooming in/out increment is now augmented by whether shift /ctrl keyboard modifiers are set (on a ticket request by Holger Marzen, thanks).
• LV2 Time position event messages for plugin atom ports that support it is now being implemented.
• Attempt to break extremely long audio file peak generation on session close or program exit (as reported by EternalX, thanks again).
• MIDI Controllers Hook and Invert properties are now properly saved for tracks (after bug report by Nicola Pandini, thanks).
• A segmentation fault when closing with VST plugins open has been hopefully fixed (after a patch by EternalX, thanks).
• Messages standard output capture has been slightly improved as for non-blocking i/o, whenever available.
• Automation curve node editing has been slightly improved in regard to time positioning and resolution.

Enjoy && Have fun.
