  • the music playback unit 120 can play music in parallel on two decks of the DJ controller 200.
  • the music audio data 121 includes a song that includes multiple acoustically separable parts. Audioally separable parts are parts such as vocals and instrument sounds that are separated within a song by, for example, frequency bands. For example, a single instrument sound may be separated into multiple parts, such as the bass drum, hi-hat, and snare sounds of a drum sound.
  • the music audio data 121 may include audio data of multiple parts separated using, for example, a known music separation engine, or may include audio data of multiple parts that have been recorded for each part from the beginning. Alternatively, audio data of multiple parts of a song being played in real time may be input as the music audio data 121.
  • the cue point setting unit 140 records the position of the cue point in the song set in response to the user's operation acquired by the operation unit 110, and the part of the multiple parts of the song to be played from the cue point as cue point information 141.
  • a cue point is a point recorded to play a song from a specific position in the song in response to the user's operation.
  • the position of the cue point in the song is recorded, for example, by a timestamp.
  • the part to be played from the cue point is set, for example, by using an ID given to each of the multiple parts of the song audio data 121.
  • cue point information such as "play only vocals from 1 minute 12 seconds (chorus)", “play only drums from 0 seconds (intro)", or “play only parts other than bass from 3 minutes 12 seconds (outro)”. Note that it is not necessary for only some parts of the song to be instructed to be played by the cue point information 141, and at least some of the cue point information may instruct to play all parts of the song.
  • the cue point setting unit 140 may set multiple types of cue points that differ in the way they are recorded and in the way they behave in response to user operations. Specifically, for example, hot cues may be set that are assigned to and recorded on a cue button, which will be described later, and that immediately start playback from the cue point when the user operates it, or memory cues may be set that are automatically sorted and recorded in chronological order, and that go into playback standby mode when the user operates it, and then start playback from the cue point when the next operation is performed.
  • hot cues may be set that are assigned to and recorded on a cue button, which will be described later, and that immediately start playback from the cue point when the user operates it
  • memory cues may be set that are automatically sorted and recorded in chronological order, and that go into playback standby mode when the user operates it, and then start playback from the cue point when the next operation is performed.
  • the cue point setting unit 140 sets a cue point in response to an operation performed by the user on the operation unit 110 while listening to the sound of the music being output by, for example, the music playback unit 120 and the audio output unit 130.
  • Either the position of the cue point or the part to be played may be set first.
  • the user may perform an operation to set the position of the cue point and then an operation to select the part to be played from the set cue point, or may perform an operation to select the part to be played first and then an operation to set the position of the cue point.
  • the cue point setting unit 140 may set the part to be played from the cue point once and record the cue point information 141, and then update the cue point information 141 in accordance with the user's operation to change the part to be played from the cue point.
  • the playback position control unit 150 plays the song from a cue point in the song in response to the user's operation acquired by the operation unit 110 and the cue point information 141.
  • the cue point information 141 may be set by the cue point setting unit 140 of the PC 100, or may be set by an external device and transmitted to the PC 100.
  • the playback position control unit 150 controls the music playback unit 120 so that playback of the song begins from the playback position indicated by the cue point information 141 at the timing specified by the user's operation.
  • the playback part control unit 160 plays only some of the multiple parts of the song when the song is played from the cue point, in response to the user's operation acquired by the operation unit 110 and the cue point information 141. Specifically, the playback part control unit 160 controls the song playback unit 120 to play only some of the multiple parts of the song by activating some of the audio data of the multiple parts included in the song audio data 121 and deactivating the rest. This allows, for example, a song that was played with all parts to be played with only some parts, or a song that was played with one part to be played with another part, when playback of the song starts from the cue point. Separately, the playback part control unit 160 may be able to play a song that was played with only some parts with all parts when playback of the song starts from the cue point.
  • the cue point setting unit 140 sets one of the two parts as the part to be played from the cue point. Also, if a song contains three or more parts, the cue point setting unit 140 may set only one part as the part to be played from the cue point, or may set two or more parts.

  • a screen 500 is displayed as a GUI (Graphical User Interface) on the display 101 of the PC 100 shown in FIG. 1.
  • the screen 500 includes a currently playing waveform 510, an editing waveform 520, a track selection button 530, and a cue point assignment button 540.
  • the currently playing waveform 510 displays the waveform of the song being played by the song playback unit 120.
  • the editing waveform 520 displays the waveform of the song used to set a cue point by the cue point setting unit 140.
  • a user sets a cue point that plays a part selected by the track selection button 530 from a position in the song indicated by the playback head of the editing waveform, and assigns it to the cue point assignment button 540.
  • track selection buttons 530 include buttons 531-534 for selecting one or more of up to four parts contained in a song, and button 535 for selecting all parts.
  • cue point assignment buttons 540 include buttons 541-548 to which up to eight cue points can be assigned. Note that, because it is already known that song parts can be selected and song playback positions can be set individually using cue points, the settings are not limited to the illustrated example, and various known GUIs can be used.
  • step S101 when the music playback unit 120 is playing a song (step S101), a cue point setting operation is performed. Specifically, the cue point setting unit 140 sets the position of the cue point (step S102) and sets the part to be played from the cue point (step S103) according to the user's operation acquired by the operation unit 110. Note that steps S102 and S103 may be performed almost simultaneously or with a time difference, and either may be performed first.
  • the cue point setting unit 140 records cue point information 141 including the position of the set cue point and information on the part to be played (step S104).
  • step S105 The above processing is repeated until the user performs an end operation (step S105), and multiple cue points may be set for one song, for example.
  • a procedure may be performed in which the user listens to the song by playing it at the playback position and part set before recording the cue point information.
  • step S201 when the music playback unit 120 is playing music (step S201), an instruction to play music from a cue point is given according to a user operation acquired by the operation unit 110 (step S202).
  • step S203 the playback position control unit 150 sets the playback start position of the music (step S203)
  • step S204 the playback part control unit 160 sets the part of the music to be played (step S204)
  • the music is played from the set position with the set part (step S201).
  • steps S203 and S204 may be executed first, or may be executed almost simultaneously, as long as they are completed before the music is played from the cue point. If playback from the cue point is not instructed, the music continues to be played until it ends (step S205). Although not shown, in addition to steps S202 to S204, the user may be able to perform an operation to play a song from a cue point without changing the part being played, or an operation to change the part being played without changing the playback position.
