The Ardour project is pleased to announce the release of 4.4. Like 4.2,
this is primarily a bug fix release, but the list of fixes is long.
Stability and correctness with MIDI is much improved, and most users will
benefit in some way from the long list of fixes.
The significant GUI changes we planned to include in this release will now
be in a soon-to-appear future version (or in the nightly builds in the very
GCC 5 Compatibility on Linux
Linux distributions built with the latest version of the GNU C Compiler
(gcc5) have recently started to become available. There are no issues for
most users but if you use plugins written in the C++ language then they
must be compiled with the same version of gcc used to build Ardour (or any
other plugin host). Robin Gareus has already done the required work to
create gcc5-built versions of Ardour, but for now they are available only
on the nightly site <http://nightly.ardour.org/>. A future release will see
them available via the official release site. If you do not use these
plugins, then any version of Ardour will work on your Linux system,
regardless of which version of gcc it was built with.
- Fixed solo logic in deep ways. Most notably this prevents various
"stuck solo" problems, but also a number of other issues with solo when
using complex routing between tracks and busses.
- Fixed loop recording (inadvertently broken for several releases).
- Added support for RF64 and MBWF audio file formats. These are both 64
bit file formats, capable of recording impossibly large amounts of audio.
MBWF is the 64 bit version of Broadcast WAV. .
- When using either format, if recorded files are smaller than the RIFF
(WAV) size limit, convert the header to RIFF so as to be compatible with
normal WAV-handling software.
- "Save As" will refuse to write to an existing folder/directory.
- "Save As" now defaults to the current session name as the name of the
new session, making it easier to add suffixes or otherwise tweak the name.
- Allow export of loop range without actually looping.
- Improve CPU AVX support detection.
- Fixed locating to current wallclock time for large time values.
- Fixed an issue where if an audio region was locked and locked to
video, the audio-region always stayed put and the video could only be moved
- Fixed various potential issues at session closing.
- Improve error reporting from AudioEngine when trying to configure
- Provide more details if a sessions fails to be created.
- Improve loading speed for large sessions (1000 tracks).
- Fixed a deadlock when removing tracks/busses and using JACK1.
- Prevent importing files with names like "Master" or "Click" from
causing session breakage. This also applies to attempts to name tracks or
busses with similar names.
- Ensure that correct audio is heard when region layering is changed.
- Use a single consistent method for computing DSP load on all
platforms, with all backends.
- Avoid creating excessively short regions during Strip Silence
- Avoid possible endless loop while detecting silence.
- Reduce chances of a bug in the OS X locale libraries from causing
- Fixed duplication of multiple selected regions.
- Correctly and consistently initialize track/bus group properties.
- Fixed crash during session region cleanup.
- Ensure identical XML in session files if the session does not change,
thus allowing tracking state changes in a revision control system (e.g.
- Bring Ardour's Broadcast WAVE USID value into compliance with EBU-R99.
- Fixed install on systems where using su(1) changes directories.
- Fixed broken onset analysis.
- Refuse to load LV2 plugins if their buffer size requirements cannot be
- Do not list LV2 plugins that cannot be used because they require a
- Generally improve handling of missing plugins so that sessions are not
damaged by the temporary unavailability of a plugin.
- Fixed the position of cut/copy-and-pasted plugins.
- Fixed AudioUnit port count, which allows loading various Native
Instrument plugins such as Reaktor 5.
- Added command line option to completely disable plugins.
- Fixed handling of VST audioMasterPinConnected callback.
- Allow loading of huge (10MB) VST plugin state.
* When describing keybindings below, "Primary" is used to describe Control
on Linux and Windows, and Command on OS X *
- Fixed waveform display issues when changing waveform shape from
rectified to normal or vice versa.
- Added a reset option to the context menu for the shuttle control.
- Allow creation of new points on a region envelope by clicking on the
- Added column titles in the list of "Recent Sessions".
- Alter "Stop" button in the Audio/MIDI setup dialog to function as a
"Start/Stop" button, and remove the "Apply" button.
- Fixed issues where waveform display used the wrong data.
- Cancel button for Import dialog is now a Close button.
- Change OK button on Import dialog to "Import".
- Correctly display plugin parameter values when dragging automation
- Fixed log-scaled automation parameter display.
- Visually indicate regions waiting for their audio peak data to be
- Fixed inconsistent text sizing in the editing canvas.
- Added avoiding GPU rendering to preferences dialog. This is helpful on
some Linux systems with buggy video device drivers. See Edit >
Preferences > GUI > Disable Graphics Hardware Acceleration.
- Allow overriding lock-to-video when moving video or audio.
- Fixed drawing of short cross fades.
- Sort "Recent Sessions" by modification time.
- Don't try to split a region when dragging.
- Update Import dialog options when/if track selection changes.
- Fixed marker display after a marker is removed.
- When editing a clock display, swallow illlegal keys rather than
passing them onto the main window where they might have some unintended
- Primary-Shift-click on the solo lock button now applies to all
tracks/busses, consistent with Primary-Shift-click on other buttons.
- Avoid a case where the color of selected text was the same as the
background, making it invisible.
- Correctly set waveform height when switching between stacked and
overlaid view modes.
- Make all entries in the track list context menu actually work.
- Fixed incorrect setting for "Import to Region List" on first use of
the import dialog.
- Avoid duplicate shortcut folders in file browsers.
- Drop the use of C++ fstreams to reduce issues with non-Latin
characters in filenames on Windows.
- Option to install without WASAPI support, which helps startup on
- Close all files before Session > Cleanup, so that it can work on
- Fixed MIDI Sysex I/O on Windows.
- Fixed issues with onset analysis on Windows.
- Added "Refresh Devices" button to the Audio/MIDI setup dialog on
Windows to pick up new
- Added a "None" device to the PortAudio backend, allowing disabling
either input or output, but not both. devices or external ASIO buffer
- Added an easy way to reset the click sound(s) to their defaults.
- The click sounds are now normalized to -6dBFS.
- Allow enabling/disabling of the click "emphasis" sound.
- MIDI Tracer window now shows MSB of appropriate messages.
- Fixed a subtle bug in ordering of MIDI events that caused missing
- Highlight notes based on mouse position on track header keyboard.
- Exclude MIDI CC parameters with no data from being displayed when
"Show Existing Automation" is chosen.
- Fixed issues with linked (cloned) MIDI regions on different tracks.
- Fixed issues with de-selecting MIDI notes.
- Handle a missing MIDI file without crashing.
MIDI/Mackie Control Surfaces
- Save/restore generic MIDI control surface "motorized" setting.
- New Mackie Control device files for configurations with 3 surfaces.
- A substantial amount of work has been done on Mackie Control support.
There is no simple summary that would describe all the changes, but suffice
it to say that (1) it works much better (2) it is easier to get started (3)
has been tested on an even wider range of equipment.
