Qtractor 0.9.36 - An Autumn'23 Release


Qtractor 0.9.36 (autumn'23) is released!


  • Multiple audio and/or MIDI files may now appear as arguments on the command line and get immediately imported into a new session; also, any audio or MIDI file may now be promptly imported into a new session from the main File/Open... dialog.
  • New MIDI clip tool option added: Rescale/Invert.
  • Introducing brand new MIDI clip tool: Tempo ramp.
  • Disable or better hide the Add Tracks option on the MIDI tracks export dialog.
  • Fixed a yearlong bug in MIDI file import/export of tempo, time and key signatures and markers, to severely wrong locations.
  • Enable Aux-Send inserts on output buses, but list possible target buses only; audio output buses are now listed as possible targets iif they follow or succeed the source one (in internal processing order).
  • Fixed MIDI tracks latency compensation, now working as expected.
  • Show current/total plugins latency on the Track properties dialog,
  • Fixed MIDI Step-input for non-zero offset clips.


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.
