This fixes an issue with some soundcards e.g. "AxeFx III".
Device configuration fails unless set_hwpar() is performed
for the capture device before configuring the playack
device (half duplex is fine, too).
Resolve ambiguity between Dialog::add_button() and add_button member,
also use clicked signal for ArdourButton.
signal_button_press_event() only works with
ArdourButton::set_fallthrough_to_parent
When a route's output is connected to multiple busses, re-establishing
port-connections on session-load calls Route::output_change_handler
multiple times.
Implicit solo counts are saved and restored by the route's SoloControl,
however the output_change_handler invalidated it on session load.
Since connections are restored iteratively, counting soloed downstream
routes will yield an incorrect result until all connections are
established.
This fixes the issue that implicit solo is lost on session-reload
in case a route has multiple connections with different up/downstream
solo states.
This restores using the distinct colors for cursor and edited text,
which was lost in the theme overhaul in 7f80883eb1.
Since delta-clocks are not editable, the same color is used for
delta display and the edit cursor (orange in the default theme).
* Include main-out channel-count when bouncing the output
* Do not de-activate disk-reader and mains-out when freezing a track
* Ignore meter when counting channels
When copying a plugin via drag/drop or copying plugin state, use
the main instance only. Plugins will later be replicated as
needed when configuring processors.
TMM ports cannot exist without a backend.
This fixes crashes where the PortEngine is re-initialized
(backend change):
Previously, TMM ports were only dropped (and recreated)
in TMM::restart() called from ARDOUR::init_post_engine().
When starting a new backend the old one is already destroyed,
but TM still held reference to Ports owned by that backend.
Calling the port's d'tor caused a memory corruption trying to
acquire the backend's port_callback_mutex:
e.g. When creating new session with a different backend
from a running instance, or unit-test after call to
AudioEngine::destroy(): https://pastebin.com/4D6pLA5s
