Note that the part and the timbre name may be automatically acquired from the tone input
device 39 connected to the music generation device main body 1.
[0046]
(4) From the music data stored in the storage 33, the music generation apparatus selects, for
each part, one corresponding to the genre and meter selected by the user.
However, song data corresponding to the part that the user intends to play is excluded.
In addition, if there is a plurality of music data corresponding to the genre and beat selected by
the user, one arbitrary part is selected.
[0047]
If there are a plurality of music data corresponding to the genre and beat selected by the user,
they may be displayed to allow the user to select one of them.
[0048]
(5) After that, when the user presses the play button 15, the music generation device reproduces
the music data selected in (4).

The part may be automatically acquired from the tone input device 39 connected to the music
generation device main body 1.
[0057]
The music generation device has information indicating that it is set in the session mode,
information indicating whether or not it is in session, predetermined genres and beats selected
by the user, and information related to the part selected by the user. Send at time intervals.
[0058]
It should be noted that the music generation device which has already conducted the session has
predetermined information indicating that the session mode is set, information indicating that
the session is in progress, and information indicating the genre of the performance being played
and the time signature etc. While transmitting at time intervals, the performance data etc. which
are in session are transmitted.
[0059]
The user moves to find the other party in the session.
[0060]
The music generating device searches for another music generating device set in the session
mode (step 4).
This is done by receiving information indicating that it is set to the session mode transmitted
from another music generating device.
[0061]
When the music generation device finds another music generation device set in the session
mode, the other music generation device has already made a session based on the information
sent from the other music generation device. It is determined whether or not it is performed (step
5).
10-04-2019
13
[0062]
If the other music generation device has already performed a session, the music generation
device acquires the genre and beat of the performance being held based on the information sent
from the other music generation device. Then, it is determined whether the acquired genre and
beat match the genre and beat input by the user in step 2 (step 6).
[0063]
If the genre and beat of the performance being session do not match the genre and beat input by
the user, the process returns to step 4.
[0064]
If the genre and beat of the playing performance match the genre and the beat input by the user,
the music generating device receives the playing performance data transmitted from the other
music generating device. And reproduce and output (step 7).
In addition, when the genre and beat of the performance being sessioned encounter a plurality of
sessions matching the genre and beat input by the user, the session group is switched each time
the session switching button 17 is pressed by the user. .
[0065]
The user listens to this performance to decide whether or not to participate in this session, 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).
[0066]
In step 5 above, if the other music generation device found does not perform a session, whether
the genre and the time signature to be played match based on the information transmitted from
the other music generation device. It is determined (step 9).
10-04-2019
14
[0067]
If the genre and the beat do not match, the process returns to step 4.
If the genre to be played and the time signature match, session start processing is performed
(step 11).
[0068]
FIG. 7 shows the procedure of the session start process of step 11 of FIG.
[0069]
One terminal to be a master is selected from all the music generation devices participating in the
session (step 11).
The selection method may be random, or the priority may be set in advance for each music
generation device, and the highest priority may be selected as the master.
[0070]
In response to an instruction from the master, the performance of all music generators
participating in the session is paused (step 12).
[0071]
Next, in accordance with an instruction from the master, sound effects such as fill-in or a DJ
signal ("So-session time zone") are output from all the music generation devices participating in
the session (step 13).
[0072]
10-04-2019
15
Next, the master collects song data to be an 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.
The music data (corresponding to the designated genre and meter) corresponding to the
remaining part is collected from all music generators participating in the session.
[0073]
Thereafter, the master reproduces the music data to be accompaniment collected in step 14 and
transmits the music data to be accompaniment (step 15).
At this time, the master transmits a clock for synchronization to music generators other than the
master participating in the session.
The music generation apparatus other than the master participating in the session receives music
data and a clock serving as accompaniment transmitted from the master, and reproduces and
outputs the received music data based on the received clock (step 16).
[0074]
The users of all the music generators participating in the session perform their performance
using their own musical tone input device in accordance with the accompaniment (step 17).
Each music generation device transmits musical tones input from the musical tone input device.
In addition, each music generation device superimposes the musical tone input from the musical
tone input device, the accompaniment sound received from the master, and the musical tone
10-04-2019
16
received from another music generation device, and uses one or both of the headphone 37 and
the speaker 44. Output from (step 18).
At this time, if a sound is output from the speaker 44, it is possible to let another person hear the
session.
[0075]
In the case where each music generation apparatus to perform a session acquires and stores
song data to be an accompaniment in advance, the master does not need to collect song data to
be an accompaniment.
That is, step 14 is unnecessary.
Also, in this case, in step 15, the master does not transmit song data to be an accompaniment,
but transmits only a clock for synchronization to a music generation device other than the master
participating in the session.
Each music generation device reproduces and outputs music data to be an accompaniment in
synchronization with a clock received from the master.
[0076]
FIG. 8 shows the session synchronization processing procedure of step 10 of FIG.
[0077]
One terminal to be a master is selected from the music generating device performing the session
and all the music generating devices attempting to participate in the session (step 21).
[0078]
The master transmits a clock for synchronizing with music data to be accompaniment (step 22).
10-04-2019
17
The music generation apparatus other than the master receives the music data and the
accompaniment data transmitted from the master, and reproduces and outputs the received
accompaniment music data based on the received clock (step 23).
[0079]
The users of all the music generators perform their performances using their own musical tone
input device in accordance with the accompaniment (step 24).
Each music generation device transmits musical tones input from the musical tone input device.
In addition, each music generation device superimposes the musical tone input from the musical
tone input device, the accompaniment sound received from the master, and the musical tone
received from another music generation device, and uses one or both of the headphone 37 and
the speaker 44. Output from (step 25). At this time, if a sound is output from the speaker 44, it is
possible to let another person hear the session.
[0080]
When the music generation device that is performing the session and the music generation
device that is going to participate in the session previously acquire and store song data to be
accompaniment, the master does not transmit the song data to be accompaniment , It is sufficient
to transmit only the clock for achieving synchronization to music generators other than the
master. Each music generation device reproduces and outputs music data to be an
accompaniment in synchronization with a clock received from the master.
[0081]
[3] Description of operation in music data transfer mode
[0082]
In the music data transfer mode, music data stored in another music generating device or music
