[LAU] [ANN] 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 [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.
