Note lines on a MIDI-track were able to exceed the time-axis' height
towards the top. If a MIDI track was at the top, the TAV's canvas-group
would increase the overall bounding-box of the track-area and allow
tracks to visually bleed into the time markers group.
This follows the same concept as plugin-UIs (keep a pointer in the backend)
to prevent multiple instances to be created from various TAVs
and RouteUIs (mixer, editor-mixer, meterbridge,..)
VST's effSetBypass may fail even though a plugin CanDo "bypass",
and it can be case-by-case (depending on plugin-settings).
This codepath is not yet active, pending testing.
use_group(), use_me() filters group behavior beforehand.
ControlGroup::set_group_value() lacks context to make the decision itself
and should always apply to the group (regardless of active state):
InverseGroup allows to override both: inactive predicate and inactive group.
This needs testing, particularly since RouteGroupMember::use_group()
is no longer used and was superseded by RouteGroup::push_to_groups()
Since adding an action-groups hides existing actions with the same name,
this adds a way to look up actions first.
This fixes an issue introduced in 6af51b52ff (both window_manager.cc
and ardour_ui_ed.cc use the "Window" group.
* consistent behavior (Route, VCA)
* non-modal
* a single color picker for each RouteUI/VCA at most
* fix bug: VCA picker staying around even when VCA was deleted
This fixes a bug for me:
Measure lines appear & disappear during playback, at certain zoom scales.
I think this is because the unecessary offset was causing beat_density to vary unnecessarily while rolling.
