  • Filter out zero-duration note events when importing MIDI files.
  • Fixed step input on offsetted MIDI clips.
  • Fixed audio Aux-Sends inserted on audio input buses to not affect output buses processing order anymore.
  • Clip/Merge, Export... now allowed on simple highlighted clips.
  • Make sure to ask whether to replace already existing files on Clip/Merge, Export...
  • Make sure all LV2 plug-in state paths are stored as relative.

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.

QjackCtl 1.0.5 - A Mid-Winter'26 Release

Submitted by rncbc on

Hi everyone!

QjackCtl 1.0.5 (mid-winter'26) is out!

QjackCtl is an aged yet modern, not so simple anymore, Qt application to control the JACK sound server, for the Linux Audio infrastructure.

Change-log:

  • Graph: Save node positions as soon as they are taken or moved around, avoiding accidental re-positioning to the previous or original state.
  • Get rid of CONFIG_WAYLAND build config option; add underlying platform name (eg. xcb, wayland) to Qt version string.
