Another month, another Ardour3 beta! More than 130 fixes and
changes since beta1, all documented below. Download at:

 Linux x86 (32 bit) binary package:

 Linux x86_64 (64 bit) binary package:

 OS X Intel binary package:


* You **must** be using JackOSX 0.89 (the
  latest release). Earlier versions of JackOSX will cause
  strange behaviour and/or crashes. Upgrading from existing
  JackOSX versions is recommended anyway, even if you are
  using it with Ardour2 or other software.

* If you want access to any hardware MIDI ports and/or
  other MIDI software on your OS X system, you need to start
  JACK with JackPilot and ensure that the CoreMIDI bridge is
  enabled in its preferences settings.

* As with beta1 and the zero-cost prebuilt versions of
  Ardour, plugin preset saving is disabled.

My hope is that there will be two more betas before Ardour
3.0. Beta 3 will concentrate on remaining matters of
functionality that must work, and Beta 4 will focus mostly
on polish and the first time user experience. I doubt that
these boundaries will be strictly adhered to, tough.


* Completely new implementation of the audio clocks used throughout Ardour (for
    docs on using them, please see: http://ardour.org/a3_features_clocks)
* Lots of work on Ardour's handling of tempo and meter.
    *  tempo and only tempo affects the computation of frames_per_beat()
    *  allow tempo changes on any beat of a bar
    * fix lots of bugs associated with dragging and place new tempo or
meter markers
    *  provide config parameter to allow non-quarter note pulses; off
by default; no GUI to reset it at this point
* Save templates as directories with plugin state. Unfortunately breaks
    existing Ardour3 session templates. They can be fixed by
    moving the .template file into a new directory with the
    name of the template (minus the .template)
* Re-work layering in possibly debatable ways. Preliminary documation
at doc/layering.
* Add option to glue new regions to bars and beats
* On OS X, Ardour3 now uses ~/Library/Preferences/Ardour3 as its "user config
folder", rather than ~/.config/ardour3.


* Label solo iso / solo lock buttons even on narrow strips
* Make activate/deactivate all only operate on visible processors (and
also exclude the fader from its effect)
* add a signal so that if the Big Clock is closed, the edit window can
grab focus back
* Remove solo buttons from the master route in the route list
* Remove panner altogether, if necessary, when configuring the UI panning
* Tooltips for mixer strip width and hide button
* Remove ghost notes when actual notes are deleted
* Reset a mixer strip's peak display when its route is changed (notably affects
  the editor mixer strip)
* Change label of audition button in region editor to "Audition" to
indicate *how* it will be heard (via the audition bus, not in-place)
* Fix use of GTK Dialog windows, by (a) adding buttons to all actual
Dialogs (b) using Windows for all non-dialog windows. Fixes
     problems for users of GNOME 3 where Dialogs do not have the usual
window manager decoration, and so could not be closed.
* Fix mute display on session load
* Fix for AFL/PFL button misbehaviour
* Start autoscroll in from the right-hand edge of the screen if the
editor list is not in view, so that autoscroll kind-of works in this
* Display underscores in plugin names correctly
* Fix autoscroll fudge calculations
* Remove code to zoom on up/down mouse movement when dragging the playhead
* Save location UI clock mode in Session instant.xml
* Make fader belts wider to take up maximum space and line up with things nicely
* Shift-ctrl-click on a mixer width button toggles width of all strips
* Fix partial visibility of piano roll when changing MIDI track height
in various way
* Set up piano roll and scroomer objects before the MidiTimeAxisView
height gets set up, so that their visibility can be initialised
* New zoom button icons
* Set ellipsizing behaviour for mixer strip name button
* Add full name tooltip to name button
* Fix a number of fundamental issues with Gtkmm2ext::Prompter, mostly
centered on bad behaviour when Enter/Return is pressed
* Allow Cancel button on route rename dialog to actually cancel
* Rename new send options to be more clear on the difference;
* Relabel "sends" button to say "Aux Sends" to be clearer on what it does
* Restore the functionality of the join-play-range button,
* Desensitize make-mono-regions as appropriate
* Add tooltips to editor region list column headers
* Add tooltips to the editor track/bus list column headers
* Add tooltips to the editor route group list column headers
* Fix column expansion behaviour of editor region list
* New configuration variable to control display of periodic MIDI
messages (MIDI Clock, MTC)
* Gradient-ized waveforms
* Fix somewhat unlikely crash on doing add note; start drag to resize
note; undo; finish drag to resize note.
* Do not show panner GUI in external send UI, to avoid confusion
* Consistent colors for selected treeview rows
* Fix scroll wheel handling on both gain faders and parameter controls
in automation track headers
* Add monitoring column to route group list;
* Make click in blank area of route list and route group list cancel
selection and/or name editing
* Add color editor button to editor route groups list
* Add "enabled" column to editor route groups list
* Clarify meaning of route group tab context menu items
* Remove visible "sound notes" button,add Config parameter to control this
* Fix setup of gain envelope visible menu item.
* Use same modifiers with the mouse wheel in the summary as in the editor
* Fix scroll-wheel direction in summary
* Fix, or at least improve, management of the editor toolbar when
maximising editing space
* Fix reversed scroll in timeline rulers wrt editor pane
* Add middle-clock-on-range/marker-clock to locate there
* Tweak constants that affect whether/where trimming cursors are shown
for MIDI notes, to avoid making it so hard to drag relatively small
* Make a few region/track context menu actions able to use the mouse
location where the context click occured
   (insert-patch-change, paste )
* Fix comparison of beats to frames when deciding whether to show a patch change
* Improve layout and display of CD range info in location display
* Make the export ranges view expand with the export dialogue.
* Show generic plugin UI toolbar (for presets etc.) on LV2 UIs (except
* Show panner drag information tool-tip style, and also show it when
the button is pressed to start a drag
* Make the MidiRegionSelection notice when its MidiRegionViews go
away; fixes one source of memory corruption during MIDI edits
* Add select all / deselect all to timespan section of export dialogue
* Tweak up size+spacing of main menu bar info box
* Make sure that create drags make notes with a minimum length of 1 tick
* Use a Drag class for midi note selection, so that it gets autoscroll
* Remove OS X specific code for key editor binding displays
* Use the correct display for key accelerators (key "label" not key "name")
* Show pulse note type in tempo markers (optionally)


* Make Carbon GUI support for AU's optional at compile time
* Fixes for Windows VST support build
* Share code between native linux VST and windows/x86 VST support,
where possible
* Implement the LV2 urid extension and remove implementation of
(experimental) LV2 uri-unmap extension
* Support new URIs for LV2 presets (Old stuff continues to work for
Calf, but it'd sure be nice if it would be updated)
* Implement latest LV2 state extension (0.4)
   (Corresponding patch to LinuxSampler available here:
* Save references to external files in LV2 state as symbolic links

      With this commit it is possible to archive sessions that contain
plugins with
      complex file-containing state (e.g. Linuxsampler with a sample
bank loaded)
      with any archive tool, e.g.:

        tar -hjcf session.tar.bz2 session

      Which will give you a fully self-contained archive of everything
used in the
      session, so you can e.g. send it to a collaborator who may not
have the same
      sample banks in the same place as you and it will work.


* Slightly unpleasant fix for creation of tracks from templates
* Fix erroneous setup of order keys when tracks have children: order
keys relate to the actual tracks only, and ignore child automation
* Fill extra channels if monitor sends have more outputs than inputs
* Re-add code to support do-not-record-plugins
* Add track-solo-toggle / track-mute-toggle to make them bindable to keys
* Sort session routes before trying to do the group tabs collection
* Provide and use mechanisms for resolving translation ambiguity
* Fix mis-ordering of MIDI events when merging MidiBuffers in-place
* Patch from colinf to fix build on gtkmm versions prior to 2.28
* Don't load program 0 on initialising a VST
* Fix crash on save caused by never having shown the locations editor
* Fix confusion with midi note selection and channel selection
* Use compiler-generated _LP64 macro to detect x86_64 rather than USE_X86_64_ASM
* Made region export default to use region gain and fades
* Fix failure to find export formats in packages
* Be consistent in the way we merge environment-set search paths and
pre-defined ones
* Make Freesound support default to true
* Provide sensible default step and page sizes for
AutomationControllers based on parameter max and min values
* Fix incorrect position of a copied region
* Fix up some logic so that we don't replicate the session dir path
twice in the search path(s)
* Check that adding a port to an IO is ok with the processors in its
route, and raise an error if not
* Centralize legal-session-name-checkng and include : and ; in
characters that we disallow, because they conflict with search path
conventions on *nix and windows
* Use session_name_is_legal for snapshots too
* Remove unnecessary silencing of unused plugin inputs; unnecessary as
(LADSPA/LV2 at least) connect_and_run routines pass in silent buffers
for inputs that are not in the ChanMapping.  The explicit silencing
also failed if the plugin had more inputs than any processor on the
* Compute delta time correctly when appending events to an SMF object;
the converter must be used to convert a source time, not a delta time,
otherwise tempo / meter changes are not correctly accounted for
* Fix for most (all? we can dream ...) issues involved in #4399
(editing multiply-applies operations to playlists used more than
once), and as a side-issue, fix playlist selection which broke when we
hid Diskstreams inside Tracks by using orig_track_id() rather than
* Move note creation code into a Drag; fix snapping of note starts
when drag-created
* Keep track of MIDI region's start positions in beats, to match the
source, so that starts are not corrupted when tempos change
* Fix lack of marker/range display in marker/range list at startup,
and tweak location display quite a bit to improve things
* Clarify stop-at-session-end behaviour
* Patch from roy vegard to stop feedback from causing jumps when a
MIDI controller and ardour are out of sync
* Send sustain=off and all-notes-off when a MIDI track is muted
* Tidy up monitoring slightly so that it gets closer to matching chris
goddard's truth table for the various different states.
* Grab bag of changes correcting and improving the way MIDI note
on/off tracking is done. may/should fix a number of problem with
spurious note-offs under a variety of circumstances
* Do not write sequential same-value automation data into a
ControlList (bug fix)
* Thin AutomationList data when reloading from disk (similar code as
Ben's from Ardour 2.X & Mixbus, but without user-adjustable thinning
density at present).
* Move patch changes when inserting silence at the start of a model.
* Add configure option to raise a FP exception when a denormal is
detected (--denormal-exception)
* Create Freesound working directory a little more lazily so that a
Freesound directory doesn't appear in the user's home directory
without ever using Freesound.
* Don't round control list events when x-scaling them; prevents large
loss of accuracy with xfades when they are scaled to be small and then
expanded again
* Use the correct flag for DAZ and default to using FTZ and DAZ
denormal protection.
* Fix issues with export caused by exporting and disk butler threads
working in parallel
* Miscellaneous other crash fixes.
