Les 17 outils

• add_version≈ 852 tokens

  Saves a melody as the version of an existing song for one box (a song can have one version per box: 15, 20, 30 notes or freestyle). Replaces that box's version if it exists. Works on the signed-in person's songs, or on a song saved without an account if you pass its claim_token. The melody must have no errors.

  Paramètres

  • box · string · requis · 15 | 20 | 30 | freestyle
    Music box type: "15", "20", "30" (notes) or "freestyle" (digital only). See list_music_boxes.
  • bpm · number · requis
    Tempo in beats per minute (30-300).
  • notes · array · requis
    Notes in any order, at most 2000. Only onsets matter: music boxes have no note durations.
  • song_id · string · requis
  • claim_token · string · optionnel
    Only for songs saved without an account.
  • illegal_threshold_ticks · integer · optionnel
    Minimum gap between two identical notes, in ticks (default 384 = 2 beats).

• create_song≈ 1162 tokens

  Saves a melody as a new private song. The melody must have no errors (run validate_melody or fit_melody_to_box first); warnings such as notes repeated too quickly are saved and marked, as in the composer. If the person is signed in, the song goes to their account and you get a link to open it in the composer. Without an account the song is saved anonymously and you get a claim link: give it to the person so they can keep it (valid 30 days). Set save_to_my_account to true to ask the person to sign in first (apps that cannot sign in mid-conversation should save without an account and give the claim link instead). Limits: 5 songs a day without an account, 15 a day with one.
