QLab 4.0.4

QLab provides live show control for your Mac. Create media designs for theatre, dance, composition, installation, and more. Play back audio, video, and MIDI from a single workspace.


Version 4.0.4:

  • When updating the "lock playhead to selection" general setting (via GUI or OSC), ensure that the selection is set to the playhead if they are supposed to be locked together.
  • QLab will now log current FPS playback rate for each running surface at log level 2.
  • A decoding issue that could in some cases substantially lower video playback performance compared to version 3.
  • Video playback is now much more forgiving in cases when video buffers are not staying full; the best-available video frame will be rendered in lieu of halting updates entirely.
  • Certain specific cases where Video cues would be reloaded unnecessarily, causing playback to be delayed.
  • The integrated fade envelope on Audio cues now works again.
  • Display of integrated fade curves on MIDI and Network cues (although actual output was correct).
  • Prevent several windows from going full screen that should not be able to do so.
  • Several memory leaks


OS X 10.10 or later, 64-bit processor
