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
Editor::mouse_frame only works within the track canvas. If a zoom drag is
initiated and the mouse cursor goes outside of the track canvas the zoom
position should still based on the current x position of the cursor.
- 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.
This is necessary when pango has been built without all modules included as
bundle_env_mingw.cc uses a function from the pango module and results a linker
error:
bundle_env_mingw.cc:114: undefined reference to `pango_ft2_font_map_get_type'
Minimum pango version is taken from the official build scripts.
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.
Add a clock to show the position of the edit, to remove ambiguity
If a Range is selected, pre-fill the position and length clocks
Clock format should default to the editor's secondary clock mode
