THe original determinant of width was:
double const width = ((at->mode() == Destructive) ? 2 : 0);
the conditional is always false now, so the width is a constant (zero)
Previously the dead-zone was too small (1/360). The mono/balance
panner GUI has a throw of 180 deg L<>R.
Also snapping to center didn't allow to smoothly move out of the
center. The accumulated_delta as directly applied. This caused
jumps by 4.5. degrees.
This commit reduces the deadzone to 1 degree of the azimuth
around the center.
Substantive comments associated with code in Session::plan_master_strategy.
Known not to work for reverse TC. Also, the JACK related code has not yet been tested
Audio+MIDI tracks were just MIDI tracks with an additional
audio input, and do not directly allow use of vocoders (an
instrument is loaded by default).
For pitch-correction or similar use-cases one would prefer an
audio-track (main data) with MIDI only being used as control-input.
Ardour 5/6 pin-connections and side-chain offer a much nicer
workflow for this setup.
Alternatively one can get those tracks-types by manually adding
an input port to an existing track, and creating a custom template.
"AddTrackBus" is a rec_sensitive and write_sensitive action.
However the mixer bypasses this and unconditionally calls
ARDOUR_UI::instance()->add_route () in various cases
(right-click on blank space or scroller, left-click on "Add" buttons
in the VCA pane, route pane, etc).
Since those are direct events, not related actions, they need
to be explicitly ignored.
Ideally the "+" buttons would be made insensitive...
The stereo-width panner is not generally useful. In order to
change the azimuth, width has to be reduced, which usually leads
to comb-filter artifacts.
Equal power stereo, also matches the default mono to stereo panner
better than the stereo-width panner.
Last but not least, control surfaces only have an azimuth control
knob, without an easy way to reduce width, this leaves
the panner insensitive.
Direct call to Session::cleanup_sources() from ARDOUR_UI::cleanup()
didn't zero initialize size. This centralizes initialization,
so cleanup_trash_sources() does not need to explicitly clear it.
Previously when loading Ardour v2, v3-5 sessions, tracks were
created with a dummy name "toBeResetFroXML".
In v6, Track::init() creates a playlist when the track name is
not empty. Later Track::set_state() calls set_name(). When a
playlist exists, the playlist's name is set to match the track's name.
When loading v6 sessions none of this happens. A previously loaded
playlist will be assigned by ID.
Older versions identified Playlists by name and by the time the
playlist is assigned, there may be ambiguities. With the default
(track-name = playlist-name) two playlists with the same name exist:
(1) the playlist loaded from the session file
(2) the playlist created by Track::init()
Playlists are stored in an ordered std::set<shared_ptr<Playlist>>,
and name-lookup iterates over the set.
When loading an old session after starting Ardour, it is very
likely to always lookup the playlist (1), because new, later
allocations from (2) are on top of the heap and ordered last.
The session seemingly loads correctly, except for lingering,
unused empty playlists "toBeResetFroXML" renamed to "Track name"
that were never deleted.
However when loading an old session from a running instance,
ordering is mostly random, and many tracks end up with using
the empty playlist (2) instead of the correct playlist (1).
