Auto-connect is handled in a background thread, so newly created
tracks are not immediately connected.
This causes a race-condition when fan-out directly disconnects
and re-connects ports after track/bus creation.
Track name is implicit, so instead of "meter-<name>", showing a
translatable label "Meter" is sufficient and consistent with "Fader".
Under the hood, for introspection, the processor name remains as is.
This is intended to prevent crashes when unregister_port() modifies the contents of these
two members at the same time that something else is iterating over them.
This removes various duplicate code-paths leading to midi-model
updates, and expensive context-menu rebuilds. This significantly
speeds up MIDI track creation.
This exposes custom plugin model/mode. It can be useful for
the GUI to detect if effective settings have changed, and
context-menus have to be re-build.
This reverts commit fac8d84786.
This fixes fan-out. The track should be created before any tracks or
busses are created that are fed by the MIDI track.
The apparent motivation for fac8d847 was MIDNAM related
(there was code in the GUI that needed the instrument, which was
called from within ::add_routes).
This should no longer be the case, the GUI needs to pick up
instrument changes after track creation via processors changed;
besides MIDI busses were still created before the instrument.
The previous version had various issues, in particular
when creating Tracks with an instrument, the RouteUI was not
available when the signal was emitted (likely caused by recent
ee-work of Audio+MIDI and Tape track removal).
However as side-effect fanned-out tracks/busses may now
be ordered before the new instrument route.
This also fixes an edge case of multiple fan-out in case
there is more than one RouteUI instance (mixer, editor-mixer,
meter-bridge).
* Signals use camelcase.
* use a static signal, independent of the route
Previously the signal was handled by RouteUI, which
caused various issues:
* the RouteUI may not yet be available
* There may be many RouteUIs for a single Route
(mixer, editor-mixer, meter-bridge strips)
This reverts 05c77db773 (revert necessary due to 4637c49838)
Since 4637c49838 we no longer emit Located() in ::backend_sync_callback().
Therefore we must emit Located() in ::locate() even if we are
synced_to_engine().
Otherwise the playhead is not updated when synced_to_engine() in some
circumstances.
When we create a new session and are using a template from an old version of
Ardour, we should not issue the VersionMismatch dialog and not make a copy of
the session file for the old version.
We need to extend the signature of Session::load_state() to tell it if we are
creating a session from a template. Session::_is_new cannot be used for it
because it has a the semantics if to auto connect the the master bus.
