Qtractor 0.9.31 - A Winter'23 Release

Hello again,

Qtractor 0.9.31 (winter'23) is out!


  • Fixed a off-by-one rounding error on MIDI clip offset and lengths that were leaving some clips unlinked on load.
  • LXVST_PATH environment variable now accrues to VST_PATH for Linux-native VST2 plug-ins search path and not taking over in precedence anymore.
  • Fixed an old mistake on custom aliased CLAP and VST3 plugin paths.


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.
