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

rtirq update - 2021 second edition's here,
(a third time, fixed twice again)

In its latest (this) incarnation rtirq (init-script/systemd-service) now tries to save and restore its state the best it can, on start and stop respectively.

Qtractor 0.9.21 - An End-of-Winter'21 Release batch #3

Hello thrice!

Qtractor 0.9.21 (end-of-winter'21) is out!


  • Ignore snap while ALT key is pressed, on the main track-view and the MIDI clip editors (aka. piano-roll).

Vee One Suite 0.9.21 - An End-of-Winter'21 Release batch #2

Hello twice!

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 and now rolled out as the second batch to the so called QStuff* (northern) End-of-Winter'21 release season.

All still delivered 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.

Changes for this end-of-season are as follows:

  • Fixed an old lurker, causing slight differences to voice on-sets, due to a wrong initial LFO Volume ramping value.
  • Slightly improved eye-candyness to all graphic widgets, most especially on the EG widget handling, curved lines and gradient fills.
  • 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.
