It was assumed that the drag takes place within an area of musical time.
This is not true for the space before any non-initial
meter-locked tempo.
In the case of the initial tempo, there is no previous section
to perform an end-drag on.
If we've clicked on a tempo bar before the initial tempo,
don't allow anything to happen.
If it was just a click, ensure the tempo curve colour is restored.
* If the use-time-rulers-to-zoom option is enabled, -all- cursor drags can zoom.
* Behavior has been tweaked so it is easy to scroll without zooming, if you want to.
This multiplier really should be based on the "responsiveness" of the
canvas..or something. I think this is an improvement for more complex sessions
with many regions.
- a tempo marker may now be set to always continue (clamped)
this means that the end tempo of the previous section will
track the start tempo during tempo ops.
it mimics the behaviour in 5.8, with the gui indicating
the curves to be changed.
- holding down shift before initiating a tempo mark drag
alters the end tempo of the previous one as before, but
this is now a separate drag.
- restore vertical dragging of the tempo mark to alter start/
end tempo. shift during the makrker drag alters start tempo.
xontrol + shift during the drag alters end tempo.
- this implements in the intention behind the previous commit.
a tempo mark is constant until its end has been changed by a
shift-drag on the next marker.
most changes are due to a new design where tempo discontinuities at the
beginning of a ramped section may be set.
this allows easier mapping of live performance, especially in
the common case of a ramped ritard before the beginning of a new section.
feature summary:
holding constraint modifier (shift) while dragging the BBT ruler area
drags the tempo lines by changing the start tempo (as before)
holding copy modifier (control) while dragging the BBT ruler area
drags the tempo lines by changing the end tempo (ahem. not quite there)
dragging a tempo mark while holding constraint (shift) will change the
previous end tempo to match the marker position *worth trying*.
holding constraint and copy modifier (control + shift) while dragging
the BBT ruler area attempts to'pinch' or twist the surrounding tempi
sp that later ones are not repositioned (currently suffereng from
rounding errors)
- wysiwyg (during drag) when dragging more than one note across
a tempo change.
- introduces a muscal equivalent of snap_delta (only used for
note drags atm)
- split earliest note in selection into a separate function
- MRV::copy_selection() returns the equivalent _primary note
to avoid offset hell.
- RV::snap_frame_to_frame returns a MusicFrame
- prevent note drag moving before region start.
- its still a fake event, but we can at least get the snap correct.
- playlist->add_region() parameters were whacky
(for Playlist::add_region_internal()?)
snap now fills in a struct (MusicFrame) which contins a snapped frame
along with a music divisor.
this gives useful information wrt magnetic snap which may or may not
have rounded to an exact musical position.
region position may now be set musically (using quarter notes for now).
this patch fixes several problems in the current code:
- dragging a list of music-locked regions now maintains correct
musical offsets within the list.
- splitting regions using magnetic snap works correctly (#7192)
- cut drag should now work correctly with magnetic snap.
- musical length of split midi regions is no longer frame based.
If a track is selected during the drag (by moving the mouse pointer into a new track), but it was not
selected at the start, and is then de-selected (by moving the mouse back out of it), then remove
it from the selection.
* "Follow Edits" button had several behaviors that confused users.
* "Follow Range" only has 2 behaviors:
** Click anywhere in Range mode (or Smart mode) to locate the playhead.
** When you select a Range, "Play" will play the selected range.
- music-locked regions are moved by drag beat distance
(will conform to tempo changes over the drag distance)
audio-locked regions are moved by frame distance.
Currently implemented for Region and Range selections.
The new option is false/off by default to maintain existing behaviour. I'm not
sure it should require another option, perhaps Zoom to Selection should be the
default and accessing the region properties dialog can be via Modifier+double
click, but further changes can be made on user feedback etc.
Related: #7112
- this allows a midi region drag to update the visible notes
correctly while crossing MIDI streamviews with a differing
note range.
as a side effect, fixes a bug where changing
note range on a track did not draw some notes
(apply_note_range redisplays the model).
This is a common operation used for zooming in other DAWs like Ableton Live and
Cubase. To support such a usage pattern without changing the existing behaviour
of the ruler area I've made it an option that is false by default.
The behaviour of RulerDragZoom is intentionally different than a CursorDrag
that occurs in the rest of the ruler area in that it doesn't follow the snap to
grid setting and no locate related stuff occurs until button release.
There are some issues with responsiveness with more than a few hundred regions
or a large amount of MIDI events/notes.
Implements feature #6768
- adds quarter_notes_per_minute(), note_divisions_per_minute (double)
pulses_per_minute() and frames_per_quarter_note()
- this should be a no-op except for the use of tempo by
the vst callback which definitely uses quarter notes per minute.
- the XML node for TempoSection named 'beats-per-minute'
has been renamed.
- add more debugging output detecting regions whose
beat and frame position do not align on a playlist.
this is required as a check as we have never used
frame rounding on constant tempi before 8884a5723dc
- moves frame rounding up to TempoMap, which is needed
in order to calculate pulse distance without frame rounding.
- the time unit for tempo is still minute, but this now also
applies to meter sections. (new audio locked meter sections no
longer require a frame position).
- there is no longer a discontinuity
in the pulse for audio-locked meter/tempi.
- temporarily add debugging output in Region::set_position()
to test for region beat not matching region frame.
selecting regions on multiple tracks which share playlists and
dragging them has various odd side-effects. This prevents the worst
of such edge-cases.
A cleaner solution would be to not allow selecting the same region
on multiple tracks at the same time in the first place.
Comments are welcome.
- hide ghost note when add dragging.
- new note length snaps as per ghost note start (shifted snap).
- prevent ghost note from appearing before region start.
- Evoral::Beats operator!= would prevent an increment
of start_beats by intervals of less than a tick,
so its possible that other subtle problems
existed due to this kind of thing.
There were two issues:
The first is that TrimDrag::aborted was calling TrimDrag::finished with a null
GdkEvent which caused a segfault when dereferencing. So avoid that by passing
in a dummy event as we are just going to undo the operation in the next step
anyway so it shouldn't matter if it is valid(AFAICT).
The other is that TrimDrag:aborted was calling Editor::undo() which was in turn
calling TrimDrag::aborted leading to infinite recursion and stack overflow.
Calling Session::undo() directly seems to avoid that issue.
This fix feels like a bit of a hack...but it seems to work and is better than a
crash.
- Holding the constraint modifier at the time of grab gives constrained x.
- Holding the constraint modifier after the grab but before the first motion
constrains to the direction of first movement.
