- 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.
- 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.
- 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.
- TempoMap initially contains a tempo and meter.
using add_tempo/meter() using the position of an
existing section does the right thing, but prints a warning.
Use replace_tempo/meter().
- note that the negative framepos in
FrameposPlusBeatsTest::singleTempoTest() will
not pass. needs some thougt as to whether it is testing
the correct thing.
The parameters to Session::new_audio_track() changed in e0ff70cf, and
Playlist::region_list() was renamed to region_list_property() in
fce6ac0e. Update calls to these functions in the test suite to match.
A couple of tests still fail after these changes.
- this helps where tempo and meter have a somewhat circular
dependency.
MetricSection now has a musical position expressed in beats (a double).
MeterSection still has a bbt, but it really isn't needed as we have
enough information to discover the number of bars at a given beat without it.
TempoSection now has a hack to enable loading of legacy sessions, which will
ultimately be a lot cleaner than the current code.
Removing bars from tempo sections also allows us to place them
at arbitrary frames (implemented here).
Rename run-session-tests.sh script to load-save-session.sh and make it operate on
only a single session and add a separate load-save-session-collection.sh script
Add --massif option to load-save-session.sh script
Rename some poorly named variables and add some documentation to the
load-save-session.sh script
There were a few other small leaks in pbd and evoral test code but I didn't
bother changing them. Perhaps this function would be better off in PBD:: so it
can be used everywhere.
