Constructor & Destructor Documentation

Alg_time_map() [1/2]

Alg_time_map::Alg_time_map ( )

inline

This value ignored until last_tempo_flag is set; nevertheless, the default tempo is 100.

Alg_time_map() [2/2]

copy constructor

Member Function Documentation

beat_to_time()

double Alg_time_map::beat_to_time

(

double

beat

)

cut()

void Alg_time_map::cut	(	double	start,
		double	len,
		bool	units_are_seconds )

dereference()

void Alg_time_map::dereference ( )

inline

get_tempo()

double Alg_time_map::get_tempo

(

double

beat

)

get the tempo starting at beat

insert_beat()

void Alg_time_map::insert_beat	(	double	time,
		double	beat )

add a point to the map

Time map manipulations: it is prefered to call the corresponding methods in Alg_seq. If you manipulate an Alg_time_map directly, you should take care to convert all tracks that use the time map to beats or seconds as appropriate: Normally if you insert a beat you want tracks to be in time units and if you insert a tempo change you want tracks to be in beat units.

insert_beats()

void Alg_time_map::insert_beats	(	double	start,
		double	len )

insert a span of beats. If start is at a tempo change, the tempo change takes effect before the inserted beats

insert_tempo()

bool Alg_time_map::insert_tempo	(	double	tempo,
		double	beat )

insert a tempo change

insert_time()

void Alg_time_map::insert_time	(	double	start,
		double	len )

insert a span of time. If start is at a tempo change, then the span of time runs at the changed tempo

length()

long Alg_time_map::length ( )

inline

locate_beat()

long Alg_time_map::locate_beat

(

double

beat

)

locate_time()

long Alg_time_map::locate_time

(

double

time

)

paste()

void Alg_time_map::paste	(	double	start,
		Alg_track *	tr )

reference()

void Alg_time_map::reference ( )

inline

set_tempo()

bool Alg_time_map::set_tempo	(	double	tempo,
		double	start_beat,
		double	end_beat )

set the tempo over a region

show()

void Alg_time_map::show

(

		double	dur )

time_to_beat()

double Alg_time_map::time_to_beat

(

double

time

)

trim()

void Alg_time_map::trim	(	double	start,
		double	end,
		bool	units_are_seconds )
