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

The QStuff* Winter'20 Release batch #1

Season greetings y'all,

The news are about this first batch of so called QStuff*, now being rolled out, seriously: QjackCtl, Qsynth, Qsampler, QXGEdit, QmidiCtl and QmidiNet, are all jumping straight and gloriously to version 0.9.0 for the (northern) Winter'20 Holiday season.

A more definitive and compelling tutorial

I just finished up a video tutorial covering the big topics related to Qtractor usage. I tried to make the case for Qtractor as a serious (perhaps best) choice for audio production on Linux. "THE Qtractor Tutorial" tracks a user through the process of choosing Qtractor in the first place, to downloading, through customization, routing and template making, through audio and midi recording, effects plugins and a wide variety of other important details that can get one more than merely 'started' on the software.


Qtractor 0.9.18 - A Fall'20 Release

Hi everyone,...

Qtractor 0.9.18 (fall'20) is out!


  • When under NSM, all top-level windows, main, mixer and connections, will always start hidden.
  • Plugin editors (GUIs) that are currently open on a track are now brought up as top-level windows immediately when a track is made current or highlighted (and Track / Auto Monitor is in effect).
  • MIDI clip editor mouse hovering effect extended to whole current note line on main view (piano-roll eye-candy++); also, the white keys on MIDI clip editor's virtual piano keyboard, are now fully highlighted.
  • Plugin search paths (View > Options... > Plugins > Paths) now lists all the default and actual existing paths, instead of a blank list.
  • Undimmed octave divider lines on the piano-roll.
  • Fixed potential crash on changing audio output buses channel count.
  • Note names display (inside note rectangles) are now an option on the MIDI clip editor (aka. piano-roll; menu View > Note Names).

Vee One Suite 0.9.18 - A Fall'20 Release

Avast ye lads, boring news ahead...

Once again, the Vee One Suite of old-school software instruments, synthv1, as a polyphonic subtractive synthesizer, samplv1, a polyphonic sampler synthesizer, drumkv1 as yet another drum-kit sampler and padthv1 as a polyphonic additive synthesizer, are here released onto the wild, just for the (Northern) Fall/Autumn'20 season...

Boring as hell, they still feature the same two kinds of deliverables:

  • 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.


  • Upstream package naming for the JACK standalone and LV2 plugin deliverables are suffixed to '-jack' and '-lv2', respectively.
  • Fixed note-off effectiveness when DCA is disabled (idle). (applies to samplv1 and drumkv1 only)
  • White keys on the virtual piano keyboard are now fully highlighted.

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

Qtractor 0.9.17 - An End-of-Summer'20 Release

So long Summer'20,

Qtractor 0.9.17 (end-of-summer'20) is released!


  • Early fixing to build for Qt >= 6.0.0 and the C++17 standard.
  • Fixed crash when changing an auto-monitored audio track's number of channels due on switching its audio output bus.
  • Avoid a complete track re-open when changing properties, unless either input or output buses are changed.
  • Fixed custom track icon selection when none is currently set.
