The QStuff* Winter'21 Release batch #1

Hello everybody,

A new batch of the QStuff* is here: QjackCtl, Qsynth, Qsampler, QXGEdit, QmidiCtl and QmidiNet, all bumping a notch to version 0.9.1 for this (boreal) Winter'21 season.

rtirq update - 2021 edition

Hi there!

New year, another rtirq update:

  • Got rid of all the deprecated sysvinit stuff.
  • Created (by mxa, thanks).
  • Version bumped to 20210113.

As always, home-brew packages are available here:

Qtractor 0.9.19 - QStuff* Winter'20 Release batch #3

Season greetings, a third and last time,

Qtractor 0.9.19 (winter'20) is released!


  • Session directory auto-name option added to the session properties dialog, as convenience.
  • Loading and saving a LV2 plugin's state has been vastly improved. IMPORTANT CAVEAT: From this moment on wards, when loading any newer saved sessions into older versions of the program, all LV2 plugins won't get their state restored correctly.
  • Track colors saturation introduced as yet another eye-candy option (cf. View/Options.../Display/Track color saturation)
  • Fixed VST3 number of channels query/report.
  • Fixed immediate crash when loading untitled or unnamed Instrument Definitions files (*.ins): base file-name is now taken as default instrument definition name or title.
  • Tempo (BPM) entry may now be specified with arbitrary precision, to at most 3 decimal positions in fractional part, while integer whole values are displayed with no decimal point.
  • Added option to keep MIDI clip editor windows (aka. piano-roll) always on top of the main window (cf. View/Options.../General/Keep editor windows always on top).
  • MIDI clip editor status-bar labels are not stretched to whole text size anymore, most specially for the current file complete path.

Vee One Suite 0.9.19 - QStuff* Winter'20 Release batch #2

Season greetings, one second time!

Once more, 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 for the (Northern) Winter'20 season...

All still delivered in the two traditional forms:

  • 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 special season release are as follows:

  • Better handling of the offset and loop ranges when in presence of very long sample files (applies to samplv1 and drumkv1 only).
  • Fixed display of old knob/dial values on status-bar.
  • Reduced formant filter coefficient slew rate, aiming to a tenfold DSP performance gain.
  • Get a chance on bringing Wayland into the picture when dealing Qt static-linked deliverables.

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.
