Ardour 5.11 released

We are pleased to announce the availability of Ardour 5.11. Like 5.10, this is primarily a bug-fix release, though it also includes VCA automation graphical editing, a new template management dialog and various other useful new features.

Release notes for other older versions are linked in the list below.


New Features

  • VCA automation can now be graphically edited.
  • VCAs can now be selected (e.g. from control surfaces).
  • Allow VCA renaming in the editor window.
  • Bindable buttons for VCA solo and mute.
  • Add select-all-tracks shortcut in the mixer window.
  • Template management dialog (both session and track templates).
  • Allow control surfaces to hide/show plugin GUIs.
  • Realtime export now allows listening to channels being exported.
  • Non-layered MIDI recording now works (MIDI regions will be trimmed at the end of recording to avoid overlaps).
  • Add an LTC generator to the Dummy backend.
  • Update colors for the "Caineville" theme.
  • Expose Off/Play states for MIDI CC "automation".
  • Allow touch automation to be done via Ardour's own knobs (e.g. trim control).

  • Fix undo being invoked from a non-GUI thread.
  • Fix crash when rapidly switching snapshots.
  • Show region name correctly in a context menu.
  • Reintroduce a command to toggle editor/mixer windows when they are tabbed.
  • Retain plugins order for copy/cut/paste + Drag-n-Drop.
  • Correctly adjust gain when selection spans multiple track/bus groups.
  • Honor groups when selecting in the mixer.

  • Fix loading bundle definitions.
  • Changing type of track/bus in the add track/bus dialog no longer resets the name, if edited.

  • Correct note length setting and display in the note edit dialog.
  • Time info box updates its length display correctly across a tempo change.
  • Indicate region positional lock style with various UTF-8 glyphs (Beamed 1/8th notes => music position lock).
