Qtractor 1.5.4 - An Early Spring'25 Release

Hi everyone,

Qtractor 1.5.4 (early-spring'25) released!

Change-log:

  • Fixed non-zero clip offset conversion on tempo(BPM) time-scale changes.
  • MIDI clip step input and overdubbing now aggregated and fully undo/redo-able.
  • Allow MIDI step input to extend the clip length automatically; also avoid step input event duplicates (eg. playing chords in quick succession) leading to potential double-free segfault or crash.
  • Fixed MIDI track state when clips under record/overdubbing are simply removed.
  • Fixed all empty/void audio clips that are created when aborting an armed recording session.
  • MIDI clip editor (aka. piano-roll): simply allow a MIDI track to be a ghost of itself.
  • In addition to clips and markers, automation curves and tempo-map nodes now also contribute to the total session length and status.
  • Fixed command line parsing (QCommandLineParser/Option) to not exiting the application with a segfault when showing help and version information.

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.
