void all_notes_off

(

)

This function sends a 'Note Off' event for all the notes that may be sounding.

int has_accompaniment	(	Link *	links,
		int	delta_time
	)

This function checks if there is any note between the delta time of the current position of each track and new delta time. It returns 1 if there is and 0 if there is not.

void update_clocks

(

)

This function updates all the global variables that store the clocks values.

long int get_current_time

(

)

This function gets the current computer time and returns its value in milliseconds.

void after_match	(	Link	link,
		Link *	links
	)

This function handles the execution of the program after a match has been detected.

void matching

(

)

This function is the kernel of this program. We can divide it into four parts: (1) first, it handles the musician input in real time; (2) compares it with the score using the LCS problem algorithm; (3) updates the virtual clock according to the musician's tempo; (4) plays the accompaniment given the evolution of the virtual clock.
