Show-off my open-source stuff, mostly of the Linux Audio/MIDI genre

Qtractor 0.6.4 - The Baryon Throne beta release!

Aw, snap!

Wait, there's no big deal (nor chromium's) cosmic (mis)alignment being announced here now. Rest calm. Sorry to delude some of you :)

But, there's one (notable) leap on this tiny side and part of the universe... (or is it a multiverse? move along...) What I really want to tell is all about this happening and none else's freaking business:

Qtractor 0.6.4 (baryon throne beta) is released!

Release highlights:

  • Punch-in/out over loop-recording/take modes (NEW)
  • Latch/momentary MIDI Controllers toggle mode (NEW)
  • JACK client/port pretty-name (metadata) support (NEW)
  • Custom style and color themes (NEW)
  • Mixer strip multi-row layout (NEW)
  • Muted audio tracks monitoring on playback (FIX)
  • Clip fade-in/out resize on time-stretch (FIX)

Well, although this being yet another milestone--if one may call it that way--it also makes it official (yes, deeply engraved in stone) and definitive as a migration to Git can be, as for source-code control and management (it's a dirty job I know, but someone has to do it, right?). Nevermind. It's done.

Meanwhile, please, don't ever hesitate to ask whether any of the above does affect you some way or another. Or maybe anything else, yay? Indeed, the puzzled you feel, the better :)

This old donkey's learning new languages...

Gitpretty slowly...

that is to say we're (gosh! I mean) I am (one has to be honest, ain't we? never mind, I say), moving all our (dang, my) projects source code control to Git.

Yeah, finally. Never is too late, somehow.

And the time is now, or is it?

Anyway, in the meanwhile, the official Subversion (SVN) repositories are moving no matter what,

the old paths,

are from this moment now being migrated to:

and that's it.

Or in some old dead and wrong latin: ego dixit*, whatever ;)

nuff said.

* ps. the ego particle is the wrong one: in (old) latin, verbs don't get pronouns pre-pended, whatever again x)

[UPDATE:] the new respective Git repositories will be from now on referred as follows:

pps. regarding post caption: it's a literal translation to an old saying around here (pt_PT)--many should reckon it vaguely related to old dogs and new tricks ;)

QjackCtl 0.3.12 released, feat. JACK Pretty-names aliasing

Again, a classic needs no introduction...

QjackCtl 0.3.12 is now released!


  • JACK client/port pretty-name (metadata) support is being introduced and seamlessly integrated with old Connections client/port aliases editing (rename) (refactored from an original patch by Paul Davis, thanks). (EXPERIMENTAL)
  • Application close confirm warning is now raising the main window as visible and active for due top level display, especially applicable when minimized to the system tray.
  • Messages standard output capture has been slightly improved as for non-blocking i/o, whenever available.
  • Translations install directory change.
  • Allow the build system to include an user specified LDFLAGS.
  • Missing input/output-latency parameter settings now settled for the D-BUS controlled JACK server and firewire back-end driver.

Qtractor 0.6.3 - The Armed Hadron beta release!

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:

Qtractor 0.6.3 (armed hadron beta) is now released!

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.

Vee One Suite 0.5.1 - One second official beta release!


The gang of three aka. the Vee One Suite of old-school software instruments, featuring synthv1, as a polyphonic synthesizer, samplv1, a polyphonic sampler and drumkv1, as a drum-kit sampler, are once again released in beta phase though.

The changes for this one second beta release are the following:

  • Fixed LV2 plugin relative/absolute file path state resolution. (drumkv1 only).
  • One decimal digit added to all scalar parameters and knobs.
  • Stand-alone JACK client ports outrageously renamed from a zero based numbering scheme into a plus one natural one.
  • Experimental LV2 Time/position atom-event support (Delay BPM).

Please, don't hesitate to ask whether any of the above esoteric babbles doesn't get you on to update as soon as you can. One special note goes for all the users out there of drumkv1 LV2 genre: the update is not just interesting but a must, seriously ;).

As usual, all is available in dual form:

  • a pure stand-alone JACK client with JACK-session, NSM (Non Session management) and both JACK MIDI and ALSA MIDI input support;
  • a LV2 instrument plug-in.

The Vee One Suite are free and open-source Linux Audio software, distributed under the terms of the GNU General Public License (GPL) version 2 or later.

The gore details are as follows ;)
