Qtractor is an audio/MIDI multi-track sequencer application, written in C++ on top of Qt Software's Qt4 framework, having JACK and ALSA as its main infrastructures and Linux as native and exclusive platform. Specially suited to the lone-wolf composer, arranger and (re)creative music-maker personal home-studio, it still hopes to evolve as a fairly featured desktop audio/MIDI workstation or at least, a prototypical part of it ;)

Qtractor 0.2.2 (flirty ditz) is out!

Release highlights:

• Stephen Doonan joined documentation team and revised the user manual.
• Spurious MIDI events recording bug now fixed.
• Audio track monitoring and plugin loop processing slightly improved if not fixed.
• MIDI clip editor improved precision and correct snapping.
• Multiple track mute and solo one-click toggling (NEW).
• Better MIDI connection persistance across sessions.
• Record-armed tracks aren't muted on playback anymore (NEW).
• Optimized audio clip waveform caching and drawing.
• Many more or less fixes (see change-log).

Saturday, September the 6th, I was once again pleased to attend the second National openSUSE Portuguese Meeting (ENOS), in a renewed invitation from Carlos Gonçalves. This time I had a chance to talk around the current Linux Audio/MIDI scenario and, of course, my brainchild Qtractor.

Howdy! Vacation time is now gone and the rentrée is upon us, at least on this hemisphere side of the globe ;) Silly season, beloved August, summertime it is. And before it's too late, I'm proud to announce that a new alpha has summoned to the challenge:

Qtractor 0.2.1 (fainty diva) has been released!

Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt4 framework [1]. Target platform is Linux, where the a 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.

Qtractor is free open-source software, distributed under the GNU General Public License (GPL) [15].

Thanks to Pedro Lopez-Cabanillas and Guido Scholz, this Qsynth release is now a reality. Main new features are the new rotating knob style options, first full translations, German and Spanish and last but not least, there's this Windows^TM all-in-one package available (includes FluidSynth port) for your (sick:) pleasure only. Please read below the brilliant notes from Pedro about this breakthrouth release. Yes, before's too late:

Qsynth 0.3.3 (stable) is out!

For the clueless, Qsynth is a Qt GUI frontend application to the excellent FluidSynth soft-synth library implementation for the SoundFont 2 specification.
