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.

  • 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.
