- a jump in tempo by more than 1 ntpm results in a red
tempo mark pointer.
- ignore UIConfiguration::get_allow_non_quarter_pulse()
when displaying note type in the marker text (only display
note type if we are non-quarter).
- 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.
- stretch drag (using shift on the curve) operates on
the true meaning of constant. in other words,
the only way you can make a tempo ramped is by adjusting the end
tempo (shift drag on the *next* mark). from this point onwards.
shift-drag the curve will change the start tempo and ctrl-drag
the curve will change the end (needs work). to reset the
curve to constant, 'make constant' should simply set the end
tempo (unimplemented).
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)
Tentative solution. Eventually the gain_adjustment should be moved
into the PixFader or SliderController and a dedicated API
should replace gain_adjustment.signal_value_changed()
Due to LevelMeterVBox : public LevelMeterBase, public Gtk::VBox;
LevelMeterBase::get_type() overloads Gtk::Widget::get_type(),
Glib::Object::get_type(), Atk::Implementor::get_type() etc..
Besides Ardour-style prefers not to use get_...()
