Qtractor 0.5.12 released, How to install it in Ubuntu Linux
Qtractor, free multi-track recording and sequencing software just released version 0.5.12 with many great new features.
As you may know, 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.
The latest Qtractor 0.5.12 contains below changes:
Fixed another off-by-one MIDI plugin chain timing bug, delaying the actual playback of the first MIDI event, whenever it started at the same and as long as the initial play-head position (after another ticket by Holger Marzen, thanks again).
A new LV2 host convention is in effect on plugins that expose multiple AtomPort’s in either direction: only the first input or output declared AtomPort is eligible to convey regular MIDI data events (introduced while trying Frank Kober’s forthcoming QmidiArp LV2 suite of plugins,thanks).
Zooming with shift/ctrl+mouse-wheel and pointing over the main tracks view or MIDI clip editor time ruler header’s now fixed.
A rare freezing loop condition has been fixed on the oldest of MIDI file save/write routines (after a ticket and solution by Tuomas Airaksinen, thanks again).
Copy/paste now preserving clip names (ticket by Holger Marzen, thanks).
Scaling of whole tempo map with a given factor has been added, through a spin-box and button in Tempo Map / Markers dialog, after a long overdue patch by Tuomas Airaksinen, thanks again.
When issued from main tracks view (ie. Clip/Tools menu) MIDI clip tools are now a bit more crash-resilient re. undo/redo-ability.
Session auto-save / crash-recovery support is now on trial as in View/Options…/General/Session/Auto-save current working session every 10 minutes (default on).
Plugin-list chain context-menu now includes MIDI instrument audio output options to existing non-dedicated output buses, any other than the previous hard-wired default (eg. Master).
Tracks export now allows for the mix-down/merge of multiple audio/MIDI output buses (Track/Export Tracks).
When adding new tracks, try preserving the last selected bus names, while not the default Master ones (after a suggestion from danboid aka. Daniel MacDonald, thanks).
More preparations for Qt5 configure build.
Brand new thumb-(over)view toolbar widget added to MIDI clip editor window (aka. piano-roll overview).
General MIDI RPN/NRPN 14-bit controller support is now being introduced on real-time MIDI input parsing, on standard MIDI file I/O, on MIDI Controller options and, of course, on MIDI clip and event list editor.
Pretty innocent nitpick on most thread cleanup routines.
