Ardour 9.10 Released: Live Waveform Gain Preview, Multi-Lane Automation and WallClock Sync
The open-source digital audio workstation now shows gain envelope edits directly in the waveform, lets you move automation points across lanes in one gesture, and adds a transport master that follows the system clock.
See your edits as you make them
Ardour 9.10 is a workflow release. Most of the new behaviour is about shaving seconds off everyday edits in the timeline and the MIDI editor, plus one new synchronisation option for studios and installations.
Live gain preview
Waveforms update while you drag envelope points. It is off by default.
Faster automation
Select and move points across several lanes at once, or move automation with the region.
WallClock sync
A new transport master follows the time of day for LTC and MTC timecode.

Waveform and gain envelopes
Until now, dragging a region’s gain envelope changed the sound but not the picture. The waveform stayed the same, so you judged the result by ear or by trial and error. In 9.10 the waveform follows the envelope as you move its control points, which makes it easy to see where a boost will clip or where a fade will bury a transient.
The option is disabled by default. To try it, open Preferences → Appearance → Waveform and turn on Apply region gain. Leave it off if you work with very large sessions and want to keep redraw cost low, then enable it for editing passes.
Automation and region editing
Multi-lane automation
Automation lanes are often edited one at a time, which is slow when volume, pan and plugin parameters all need the same time shift. Ardour 9.10 lets you select points across several lanes and move them together. A separate option makes region automation and gain envelopes travel with the audio regions you move, so the moves stay in sync with the audio. This second behaviour is off by default, which protects existing habits.
Trimming and fades
- ✓Trim Front and Trim Back now act on the region under the mouse pointer when nothing is selected, so you no longer need to click first.
- ✓Removing fades with keyboard commands is easier because fade lengths can shrink to their minimum without precise pointer placement.
MIDI editing
The MIDI editor gets a set of small fixes that add up for anyone who programs drums or edits velocities by hand:
- ✓Rubber-band selection of velocity markers, and dragging them in Draw mode.
- ✓Adding to an existing note selection with
Ctrl+drag, middle-click dragging for several control points, and deleting notes and points withShift+right-click. - ✓The context menu gains actions that were missing: Quantize, Legatize, Transform and Remove Overlap.
- ✓Quantizing a whole MIDI region now applies to the entire region instead of only the selected notes. Check any scripts or habits that relied on the old behaviour.
- ✓Better interface scaling for note labels and the piano keyboard.
WallClock transport master
Ardour can follow an external transport master for synchronisation. Version 9.10 adds WallClock, a master that follows the system clock. Generated LTC (linear timecode) and MTC (MIDI timecode) can therefore match the current time of day, so a session can run or be recorded against real-world timestamps.
Linux, macOS and control surfaces
| Platform or device | What changed |
|---|---|
| Linux (X11) | Fixes for resizing VST3 plugin windows. Ardour now sends corrected parameter values and timestamps at the end of processing blocks, which addresses problems reported with some VST3 plugins, including products from FabFilter. |
| macOS | The GUI is drawn through an intermediate off-screen image, which the developers say improves performance. The direct OpenGL rendering option was removed, and some redraw problems remain on certain hardware. |
| Mackie Control | Banking now works correctly and a crash when closing the surface from the GUI is fixed. |
| Steinberg CC121 | Support improvements. |
| OSC | Additional recording commands. |
| Lua scripting | More bindings, and scripts can now change GUI selections. |
Track naming is also quicker. Giving a track a name written as a numbered range, such as “Stem 1..8”, names that track and the following tracks in sequence. The same approach works when you create several tracks or buses at once. Other fixes cover MIDI notes that kept sounding after the playhead was moved, automation playback while looping, multichannel cue recording and MIDI Clock position reporting.
Should you upgrade?
For most users, yes, with the usual caution. The new editing options are opt-in or low risk, and the VST3 and control-surface fixes remove real annoyances. Use this short checklist before you update a studio machine:
- ✓Back up your session folders and the Ardour configuration before upgrading.
- ✓Open one non-critical session first and check your VST3 plugins, especially after the processing-block timing change.
- ✓If you quantize whole MIDI regions, re-test the result because the behaviour changed.
- ✓On macOS, test redraw on your hardware and note that the direct OpenGL option is gone.
- ✓Enable Apply region gain and the region-automation option only when you want them, then judge the performance on large sessions.
- ✓Check where your distribution or download source stands: the version you can install depends on your package source.
For context, 9.10 follows a run of releases this year: 9.5 in May focused on MIDI editing, and 9.8 in late August added initial support for keys and scales. The official Ardour news page lists every release.
Frequently asked questions
Is Ardour 9.10 free?
Ardour is open-source software. Check the official site for the download and support options that apply to your platform.
Do I have to turn on the new waveform behaviour?
No. Live waveform updates are disabled by default and are enabled in the Appearance preferences.
Does 9.10 change how I quantize MIDI?
Quantizing an entire MIDI region now applies to the whole region, instead of only the selected notes, so review any workflow that depended on the old result.
What is WallClock used for?
It lets timecode follow the system time of day, which helps when sessions must be tied to real-world timestamps.
Conclusion
Ardour 9.10 is not about a headline feature that changes what the DAW is. It makes everyday editing more transparent and less repetitive, adds a useful synchronisation option and fixes plugin and control-surface problems that affect real studios. If you produce music on Linux, it is an easy update to test, as long as you back up first.
