Used structures

Special structures have been created for the Virtual Music Teacher package and the detector object to store data from the score. They are:

- Structure for notes:

typedef struct _scorenote_ /*------------------- */
{
  int *pitch;          /* pitch of the note, between 0 and 127  */
  int *value_n;        /* upper number of the duration fraction */
  int *value_d;        /* lower number of the duration fraction */
  int *accent;         /* 1 if the note should be accentuated   */
  measure_t *position; /* musical time of current note          */

} scorenote_t;

- Structure for controlers:

typedef struct _scorecontroler_ /*----------------- */
{
  int *type;           /* controler type: tempo, time signature, dynamics...*/
  int *value;          /* value of the controler */
  int *value2;         /* only for controlers that need 2 values */
  measure_t *position; /* musical time of current controler */

} scorecontroler_t;

- In both, the data type measure_t has the following definition:

typedef struct _measure_t_ /*------------------- */
{
  int measure_number; /* begins with 1 and not 0 */
  int beat_number;    /* according to the time signature */
  int beat_fraction;  /* value between 0 and 95 */

} measure_t;

The main structure contains a pointer to a scorenote_t array and to a scorecontroler_t array, in which are stored all the event got from the score text file.
