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.


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.

to me, it's just another year, like it will be for the Linux desktop grail ;)
cheers && just make it happier of a new year

I'm happy when Qtractor's impeccable. c;

you'll need a account if you don't already have one;
then I'll just add you to the authors board and you can start editing away :)

No, I don't have an account at Sorry, but I already have too many accounts all over the web. I need to reduce them instead of increasing... :(
