As shown in FIG. 5, the music genre, part name, and timbre name are registered in the storage 33 in advance as a database having a tree structure.

  Hereinafter, the operation for each mode will be described.

[1] Explanation of operation in single mode

  In the single mode, the music data stored in the storage 33 can be reproduced, the sound played by the user can be output alone or superimposed with the sound being reproduced, or the sound played by the user can be stored. .

  An operation of the user and the operation of the music generating apparatus when the music generating apparatus is operated in the single mode will be described.

(1) First, the user sets the mode switch 11 to the single mode.

(2) Then, the user selects a genre and a time signature to be played.

(3) Further, the user selects a part he / she wants to play and a timbre name. Note that the part and tone name may be automatically acquired from the tone input device 39 connected to the music generating device main body 1.

(4) The music generation device selects, for each part, music data stored in the storage 33 that corresponds to the genre and time signature selected by the user. However, music data corresponding to the part that the user intends to perform is excluded. Further, when there are a plurality of pieces of music data corresponding to the genre and time selected by the user in one part, any one is selected.

  If there are a plurality of pieces of music data corresponding to the genre and time selected by the user in one part, they may be displayed so that the user can select one of them.

(5) Thereafter, when the user presses the play button 15, the music generation device plays the song data selected in (4) above. This reproduced sound is output from one or both of the headphone 37 and the speaker 44.

(6) When the user performs a performance using the musical sound input device 39 in accordance with the reproduced music data, the music generation device outputs the input performance sound superimposed on the music data being reproduced.

(7) When the user presses the recording button 14, the music generation device converts the sound input from the musical sound input device 39 into MIDI data and stores it in the storage 33 as music data. At this time, it is possible to reproduce the same performance by storing the combination of the song data corresponding to the tone input from the tone input device 39 and the song data reproduced at the same time in the song data combination table. .

  Note that the user may input a favorite music type in advance, and at the time of reproduction, the user may perform reproduction according to the favorite music type.

[2] Explanation of operation in session mode

  In the session mode, a session can be held with a person who has another music generation device.

  FIG. 6 shows a user operation and an accompanying operation of the music generation apparatus when the music generation apparatus is operated as the session mode.

  First, the user sets the mode switch 11 to the session mode (step 1).

  Then, the user selects a genre and a time signature that the user wants to session (step 2). Further, the user selects a part he / she wants to play (step 3). Note that the part may be automatically acquired from the musical sound input device 39 connected to the music generating device main body 1.

  The music generation device stores information indicating that the session mode is set, information indicating whether or not the session is in progress, a genre and a time signature selected by the user, and information on a part selected by the user that the user wants to perform. Send at time intervals.

  Note that the music generating apparatus that has already performed a session includes information indicating that the session mode is set, information indicating that the session is being performed, information indicating the genre and time signature of the performance being performed, and the like. In addition to being transmitted at time intervals, performance data and the like that are in session are transmitted.

  The user moves to find a session partner.

  The music generation device searches for another music generation device set to the session mode (step 4). This is performed by receiving information indicating that the session mode is transmitted from another music generation device.

  When the music generating device finds another music generating device set to the session mode, the other music generating device already has a session based on the information sent from the other music generating device. It is determined whether or not it is being performed (step 5).

  If the other music generation device already has a session, the music generation device acquires the performance genre and time signature of the session based on the information sent from the other music generation device. Then, it is determined whether or not the acquired genre and time signature match the genre and time signature input by the user in step 2 (step 6).

  If the genre and time signature of the performance being sessioned do not match the genre and time signature input by the user, the process returns to step 4.

  When the genre and time signature of the performance being sessioned match the genre and time signature input by the user, the music generation device receives the performance data being sessioned transmitted from the other music generation device. Are reproduced and output (step 7). When a genre and time signature of a performance in session are encountered with a plurality of sessions that match the genre and time signature input by the user, the session group is switched each time the session switching button 17 is pressed by the user. .

  The user determines whether or not to participate in this session by listening to this performance, and presses the session participation button 18 if he / she wants to participate. When the session participation button 18 is pressed (step 8), the music generation device performs a session start process (step 10).

  In step 5 above, if the other music generation device found is not in session, whether or not the genre and time signature to be played match based on the information transmitted from the other music generation device. Is determined (step 9).

  If the genre and time signature to be played do not match, the process returns to step 4. If the genre and time signature to be played match, session start processing is performed (step 11).

  FIG. 7 shows the procedure of the session start process in step 11 of FIG.

  One master terminal is selected from all music generation apparatuses participating in the session (step 11). The selection method may be random, or a priority may be set in advance for each music generation device, and the one with the highest priority may be selected as the master.

  In response to an instruction from the master, the performance of all music generating devices participating in the session is temporarily stopped (step 12).

  Next, in response to an instruction from the master, a sound effect such as a fill-in or a DJ signal ("Now, session time") is output from all music generation devices participating in the session (step 13).

  Next, the master collects music data to be accompaniment (step 14). That is, first, the parts to be played from the specified genre are listed. Remove the part that each user is going to play from the listed parts. Music data corresponding to the remaining part (corresponding to the specified genre and time signature) is collected from all the music generating devices participating in the session.

  Thereafter, the master reproduces the music data as accompaniment collected in step 14 and transmits the music data as accompaniment (step 15). At this time, the master transmits a clock for synchronization to a music generation apparatus other than the master participating in the session. The music generation apparatus other than the master participating in the session receives the music data and clock as accompaniment transmitted from the master, and reproduces and outputs the received music data based on the received clock (step 16).

  All music generation device users participating in the session perform using their musical tone input devices in accordance with the accompaniment (step 17). Each music generation device transmits the musical sound input from the musical sound input device. In addition, each music generation device superimposes the musical sound input from the musical sound input device, the accompaniment sound received from the master, and the musical sound received from the other music generation device, and either or both of the headphones 37 and the speaker 44 are overlapped. (Step 18). At this time, if a sound is output from the speaker 44, the session can be heard by another person.

  In addition, when each music generation device which is going to perform a session acquires and stores song data as an accompaniment in advance, the master does not need to collect song data as an accompaniment. That is, step 14 is not necessary. In this case, in step 15, the master does not transmit the accompaniment music data, but transmits only the clock for synchronization to the music generating apparatus other than the master participating in the session. Each music generation apparatus reproduces and outputs music data that is an accompaniment in synchronization with the clock received from the master.

  FIG. 8 shows the session synchronization processing procedure of step 10 of FIG.

  One master terminal is selected from the music generation apparatus performing the session and all the music generation apparatuses to participate in the session (step 21).

  The master transmits a clock to synchronize with the music data as accompaniment (step 22). The music generation apparatus other than the master receives the music data and clock as accompaniment transmitted from the master, and reproduces and outputs the received music data as accompaniment based on the received clock (step 23).

  All music generation device users perform using their musical tone input devices in accordance with the accompaniment (step 24). Each music generation device transmits the musical sound input from the musical sound input device. In addition, each music generation device superimposes the musical sound input from the musical sound input device, the accompaniment sound received from the master, and the musical sound received from the other music generation device, and either or both of the headphones 37 and the speaker 44 are overlapped. (Step 25). At this time, if a sound is output from the speaker 44, the session can be heard by another person.

  Note that if the music generation device that is performing the session and the music generation device that is to participate in the session have previously acquired and stored the music data that accompanies, the master does not transmit the music data that will be the accompaniment. Only the clock for synchronization can be transmitted to the music generation device other than the master. Each music generation apparatus reproduces and outputs music data that is an accompaniment in synchronization with the clock received from the master.

[3] Explanation of operation in song data transfer mode
