9674b15358 more documentation in tempo.cc, fix constant bug in pulse_at_tempo_locked() 2016-11-11 03:37:08 +11:00

1fa7c0d829 remove remaining frame api from TempoSection. 2016-11-11 03:37:08 +11:00

594137f5cc remove public pulse methods from TempoMap. 
- the only object whose musical position is not expressed in
	  quarter notes is MetricSection.
	  there is now no need to expose this.

3db68b4f9e add some documentation for TempoMap. 2016-11-11 03:37:08 +11:00

0e867b544b Refactor tempo api, include quarter-note distance in frames method. 
- 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.

715b178130 Improve bbt ruler drawing performance for large time ranges. 
- when the timeline displays many bars, zoom/autoscroll
	  speed is improved by calculating the bbt ruler scale first
	  then requesting a suitably scaled grid.

3a0a628a75 Rework duration clock and TempoMap::insert_time to include meter at offset. 
- should fix 7072

	- also fixes scroll behavior over multiple tempi.

2f72b42385 TempoSection methods deal in beats rather than pulses per minute. 
- removes note type from curve function for a slightly more
	  accurate result.

af289cab62 Remove unused methods, add tests to ensure meter divisors don't mess with Beats. 
- TempoMap::framepos_minus_beats() was only used by its test,
	  so don't build the test.

74a604d261 Fix the tempo note-type hallucination. 
- after reports that a tempo with non-4.0 note type
	  would produce a ramp in the preceding section, an incorrect
	  assumption was made leading to a bogus 'fix' that redefined
	  Tempo's pulses_per_minute().
	  the real fix was simple:
	  the ramp's function constant was calculated using the note type
	  of the proceding tempo rather than the current one.

	- this patch reverts e82482e8e9 and a4d67279e0
	  and maintains the old definition of Tempo::pulses_per_minute()

46858a2925 Consolidate the meaning of beat divisions. 
- bar and beat snapping is BBT beat based while other
	  music divisions are quarter note based. Reflect this in
	  the way exact_beat/qn is calculated.

f77d1e0a36 Don't call any Transmitter from realtime context 
This fixes a crash when TempoMap::bbt_at_frame_rt() is called
for a latent effect at position 00:00:00:00 and frame is < 0.

5c2ccc4f3e Allow negative return in TempoMap::beat_at_frame() and its exact_ variant. 
- audio-locked midi regions can be start-trimmed properly
	  when close to 1|1|0
	- a midi region placed before the first meter
	  will continue the tempo curve and first meter.

Only a couple of callers require change, as bbt_at_beat() already
deals with this.

4ddb6b74f5 Allow -ve framepos handling in TempoMap::framepos_plus_beats() 
- also handles frame positions previous to the initial
	  meter (beat_at_frame() would return 0 in this case).

140258d8ab remove reference "const int32_t&" -> const int32_t" 
this simplifies lua-bindings and also let's the compiler worry about
constant primitive types.

	  trimming are supported.
