Qtractor 1.6.0 - A Spring'26 Release

Hi all,

Qtractor 1.6.0 (spring'26) is released!

Change-log:

  • Probable fix to LV2 plug-in UIs in reflecting state/preset changes visually.
  • OSC (Open Sound Control) support has been finally introduced, similar to keyboard and MIDI controller shortcuts, it allows the discrete mapping of OSC handlers to any main menu command actions (cf. View/Options.../OSC)
  • Fixed move/copy of Audio/MIDI Insert pseudo-plugins to keep their respective send/return connections.
  • Improved main session File/Save As... requester dialogs, now taking into a better account the selected file type filters: Default session files (*.qtr), Regular session files (*.qts), Template session files (*.qtt) and Archive/zip session files (*.qtz); drop useless All files (*.*) filter.

Description:

Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt 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.

Vee One Suite 1.4.2 - A Spring'26 Release

Hi all,

The Vee One Suite, the gang-of-four old-school software instruments,

  • synthv1 as a polyphonic subtractive synthesizer;
  • samplv1 a polyphonic sampler synthesizer;
  • drumkv1 as yet another drum-kit sampler;
  • padthv1 a polyphonic additive synthesizer.

Are here updated to the (northern) Spring'26 season...

Still delivered in dual form:

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

Change-log:

  • Fixed the opening/loading sample file of an empty element, often requiring a second try to show up correctly on the LV2 Plug-in's GUI (JACK stand-alone was/is fine; applies to drumkv1 only)
  • Bumping into next development cycle (Qt >= 6.11)

qpwgraph v1.0.1 - A Spring'26 Release

Hi all,

qpwgraph v1.0.1 (spring'26) is released!

Change-log:

  • Added remote daemon name and modified state labels to the main status-bar.
  • Added command line option to connect on a remote PipeWire daemon context, by name (-r, --remote); nb. PIPEWIRE_REMOTE environment variable takes precedence though.
  • Separate the singleton/unique application instance setup logic from system-tray icon build option; add PipeWire remote-name, if any, to singleton/unique application instance identifier.
  • Settling on all boards to next development cycle (Qt >= 6.11)

Description:

qpwgraph is a graph manager dedicated to PipeWire, using the Qt C++ framework, based and pretty much like the same of QjackCtl.

Qsynth 1.0.5 - An End-of-Winter'26 Release

Hello again!

Qsynth 1.0.5 (end-of-winter'26) is out!

Qsynth is a FluidSynth GUI front-end application written in C++ around the Qt framework using Qt Designer.

Change-log:

  • Regression to the option to change the UI language translation, which was percluding the whole translations/localization effort (probably since its inception on v0.9.6).
