Now finally making the QStuff* third batch of the blooming season...

Qtractor 0.9.90 (spring'24 aka. v1.0.0-rc1) is released!


  • Prepping the unthinkable (aka. v1.0.0-rc1)

  • Custom color themes are now file based (*.conf); legacy still preserved ntl.
  • Add default GM, GS and XG standard instruments definition file.

  • Up and Down arrow-keys may now be used to change event values on the MIDI clip editor current selection (eg. note velocities).
  • MIDI clip editor now featuring lollipops for all kind of candy event values ;).
  • Make the minimum width of events on the MIDI clip editor larger, depending on screen resolution and horizontal zoom setting.
  • Avoid issuing equivalent MIDI track channel volume and panning via GM standard controllers (CC#7 and CC#10 resp.) to mitigate recursive or positive feedback loops.
  • Refined mouse-wheel control step size on the sliders of mixer strips and generic/stock plugin editor dialogs.
  • Fixed the build checks on whether to use old or newer style of LV2 include headers.
  • Introducing colored strips on the time ruler headers for loop and punch recording ranges.
  • Fixed an off-by-one(-pixel) mispositioning of selected events, while on the MIDI clip editor (aka piano-roll).
