Submitted by rncbc on

ImageImageHi again!

Qtractor 1.6.3 (late-summer'26) is out!

Change-log:

  • Fix incorrect audio clip offset after tempo change and Automatic time-stretching is in effect.
  • VST3 Plug-ins: make sure initialization and setup are done in correct order; add IDataExchangeHandler and refactor IRunLoop interfaces as singleton instances; connect processor/controller via ConnectionProxy wrappers.
  • Updated to VST3 SDK v3.8.1.build.84
  • Possible fix to incorrect audio clips offsets when undo/redoing tempo changes.
  • Plugin latency/delay compensation is now opted in to audio buses (cf. View/Buses... /Input, Output Plugins/Latency compensation).
  • Plugins are now added/inserted *after* the current selected one and appended to the list if none is actually selected as before.
  • Fixed an ugly old bug manifesting in MIDI instrument plug-in's dedicated audio outputs distorted sound (probably since v0.9.30).
  • Updated to CLAP v1.2.10
  • Fixed audio clip waveform display sudden cutoff, under certain circumstances, while recording is engaged.
  • LV2 plug-in Patch parameters/properties of the Path type, may now filter on given supported file-types.
  • Almost complete rewrite to LV2 Plug-in Worker/Schedule extension regarding multi-instance operation.
  • Mitigate an annoyance when drag-and-dropping items across plugin list-views/boxes that are shorter enough in height to overlap the default auto-scrolling margins or are showing less than a couple of items.

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.
