There is a DisplaySuspender in MidiRegionView::init(), and another invoked
during the addition of a RegionView to a StreamView. Before this change, both
suspenders were created to invoke a full "model-changed" redisplay. Since every
RegionView must be added to a StreamView to be visible, we only need the second
suspender to invoke the model-change. The first one can be just a view
change (and probably isn't necessary at all, but I did not want to change that
much at this point in time).
VelocityGhostRegion used the visibility of the "parent" note canvas item of a
lollipop canvas item to determine the lolli's visibility. But during the
construction of the MidiRegionView, the note's container is not yet visible, so
this fails.
In addition this logic would hide lollis for notes that are outside the current
visible note range of the track (because the parent note item was not visible).
This change adds a method to MidiRegionView to decide if a note is within the
region's time range, and if so, we show the lollipop item. This means that
lollis for notes outside the note-range will still be visible, which seems more
correct. In addition, the nascent condition of the parent note's container no
longer affects lolli visibility.
This prevents overlap of successive hits.
Ardour 7 added a new duration select drop-down menu,
which defaults to "Auto" (musical grid) and removed
the special case when drawing percussive notes.
It was possible to accidentally create overlapping notes,
without the user being aware of doing so.
This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
There already is a shaded coverage frame indicating
if a layer is audible. This leads to a more consistent view.
In addition changing layered mode now has to update the
colors (set_frame_color).
This fixes rendering of opaque MIDI regions (previously
MIDI regions were always transparent). This change provides a
way to "flatten" layered MIDI regions, while still allowing
to show the note-line and grid behind the regions.
In the presence of tempo-changes distinguishing between offsets and
absolute positions is signficant. It is only valid to convert absolute
times using the tempo-map
Furthermore since GUI zoom-factor is time-invariant (samples per pixel),
all GUI operations must explictly use samples (or timecnt). It is not
valid (and problematic) to use use a location dependent timepos.
1. leave tertiary-scroll for navigation and primary scroll for session timeline zoom
2. unmodified scroll in edit mode scrolls contents
3. secondary-scroll zooms in and out on contents (i.e. vertical zoom for MIDI)
4. primary-secondary scroll has the just-one-edge behavior previously provided
This also fixes Menu > Edit Delete "delete MIDI" operation.
Pressing backspace/delete calls "Delete Selection" which is
unrelated to MRV::cut_copy_clear.
Note position in samples must be calculated using absolute position
on the timeline. Otherwise the tempo-map is not applied correctly.
Previously this caused issues since the position was first
offset back by _region->position() - time relative to region left
edge - and then the tempo-map was applied.
Another solution identically would be:
(note_start + session_source_start).samples() - _region->position().samples()
