  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a functional block diagram showing a configuration of a main part of an electronic musical instrument to which the present invention is applied. The same reference numerals as those described above represent the same or equivalent parts.

  The CPU 1 controls the operation of each part of the electronic piano 100 according to a control program stored in the ROM 2. The ROM 2 stores a program for controlling the operation of the entire electronic piano, various fixed data used by the CPU 1, and the like. These programs and fixed data are accessed by the CPU 1 via the system bus SB.

  The RAM 3 stores device status information and provides a work area to the CPU 1. Various registers and flags for controlling the electronic piano 100 are defined in the RAM 3, and the RAM 3 is accessed by the CPU 1 via the system bus SB.

  The operation panel 5 includes a power switch, a tone color selection switch, various switches for specifying a single-person session performance and music selection, a display for displaying predetermined information, and the like. The panel scan circuit 4 checks the set / reset state of each switch provided on the operation panel 5, detects panel switch data that is in the ON state, and notifies the CPU 1 of it.

  The keyboard 7 is composed of a plurality of keyboards and a keyboard switch that opens and closes in conjunction with key depression and key release. The keyboard scan circuit 6 checks the state of the keyboard switch, generates touch data indicating the strength (speed) of the keyboard touch from a signal indicating on / off of the keyboard switch circuit, and displays on / off information and the keyboard number. Output. This on / off information, keyboard number, and touch data are sent to the CPU 1 via the system bus SB.

  The tone generator circuit 8 reads the original sound waveform data corresponding to the signal output from the CPU 1 from the original sound waveform memory 9, multiplies the original sound waveform data by the envelope, and outputs it to the DSP 10 as musical sound data. At this time, if a single session is designated, musical tone data of the performance by the performer and musical tone data of a plurality of performance parts for the session selected in relation to the music being played are output.

  The DSP 10 gives various effect effects to each piece of performance data output from the tone generator circuit 8 and outputs it to the mixer 11. The mixer 11 attenuates and synthesizes the musical sound data of at least one performance part with the musical sound data of the performance, and outputs this to the first reproduction system 31.

  The mixer 11 further attenuates and synthesizes the musical tone data of the performance and at least one musical tone data of the other performance parts with the musical tone data of the plurality of performance parts, and respectively synthesizes them. 32b, 32c...) In synchronization with the first reproduction system 31.

  Each of the reproduction systems 31 and 32 includes a D / A conversion circuit 12 that converts the musical tone data output from the mixer 11 into an analog musical tone signal, and an amplifier 13 that amplifies each musical tone signal. Then, the amplified musical sound signal is reproduced by the main body speaker 14. In the second reproduction system, the output of each amplifier 13 is connected to the external speaker terminals T1, T2, T3... And the external speakers 50a, 50b, 50b connected to the external speaker terminals T1, T2, T3 for each performance part. It is reproduced by 50c.

  According to the present embodiment, the performance sound by the performer is reproduced by the main body speaker 14, while the musical sound of each performance part for the session is reproduced by the external speakers 50a, 50b, 50c connected to the respective external speaker terminals. . Therefore, even in a single session, it is possible to reproduce the sense of presence, separation, and depth of sound as in an actual session with multiple people.

  Further, according to the present embodiment, the musical sound of at least one performance part is mixed with the performance sound reproduced by the main speaker, and the musical sound of the performance part reproduced by each external speaker is reproduced by the performance sound and other external speakers. Since at least one of the musical sounds of the performance part to be reproduced is mixed, the musical sound of each performance part and each performance part is not isolated, and the realism, separation, or depth of the sound can be reproduced more accurately.

  By the way, in an actual music session by a plurality of people, for example, the drum is often arranged at the center of the stage. Also, the drum and the base are often arranged relatively close to each other. Therefore, if the playback position of each performance part can be automatically set based on the rule even in a single session, it is possible to more realistically simulate the realism, separation, and depth of the sound as in an actual session.

  Therefore, in the present embodiment, the relative positional relationship between the external speaker 50 and the electronic piano 100 connected to each external speaker terminal T is registered in the ROM 2 in advance for each assumed audience seat position, and selected in a single session. The external speaker terminal T that outputs the musical sound is automatically selected according to the performance part.

  For example, when simulating a session of four people, the relative speaker arrangement shown in FIG. 2 is recommended in the instruction manual or Web catalog for the electronic piano 100 and the three external speakers 50a, 50b, 50c. Is done. The performer places the electronic piano 100 and each external speaker 50 relative to each other according to the recommendation.

  Here, if the performer desires a single session imitating a music session with an electronic piano, drum (Dr), bass (Ba), and guitar (Gt), and setting it to that effect, the rule is shown in FIG. As shown, drums, basses, and guitars are automatically assigned to the external speaker terminals T1, T2, and T3, respectively, and their musical sounds are reproduced by the corresponding external speakers.

  FIG. 4 is a flowchart showing a procedure in which the CPU 1 assigns each performance part to each external speaker terminal T in accordance with a control program stored in the ROM 2. Here, the upper limit of the number of external speakers connectable to the electronic piano 1 is 3 It shall be a stand.

  In step S1, all performance parts selected in the single-person session mode are recognized. In step S2, whether or not the external speaker 50 is connected to each external speaker terminal T1, T2, T3 is determined. In step S3, the allocation table shown as an example in FIG. 5 is referred to.

  In the assignment table, the priority of the performance part is set for each of the external speaker terminals T1, T2, and T3. For example, at the external speaker terminal T1, the priority of the drum Dr is the highest, followed by the bass Ba and the guitar Gt in this order. ing.

  In step S4, the performance part recognized in step S1 and the connection state of the speaker to each external speaker terminal T determined in step S2 are applied to the allocation table, so that each external speaker terminal T1, T2,. Assignment of each performance part to T3 is determined.

  For example, if three performance parts Dr, Ba, and Gt are recognized in step S1, and speaker connections to all external speaker terminals T are determined in step S2, the external speaker terminals T1, T2, and T3 are connected. Dr, Ba, and Gt are assigned respectively.

  If only the speaker connection to the external speaker terminals T1 and T2 is determined in step S2 even though the three performance parts Dr, Ba, and Gt are recognized in step S1, the external speaker terminal T1 is connected. Dr is assigned, and Ba and Gt are assigned to the external speaker terminal T2.

  Furthermore, if two performance parts Dr and Ba are recognized in step S1, and speaker connections to all external speaker terminals are recognized in step S2, Dr is assigned to the external speaker terminal T1, and the external speaker terminal Ba is assigned to T2. In this case, the speaker terminal T3 is not assigned. If only one external speaker terminal T is connected to the speaker, all performance parts are assigned to the external speaker terminal T.

  The unassigned speaker terminal T3 may be assigned a function as a foldback speaker for monitoring. In this way, you can monitor your performance and enjoy a one-person session in an environment closer to the actual session.

  When the assignment of each performance part to each external speaker terminal T is completed as described above, in step S5, connection is made so that each musical sound signal is output to the corresponding external speaker terminal T based on the assignment result. Switching is performed.

  As described above, according to the present embodiment, the musical sound signals of the performance parts constituting the session are automatically distributed to the external speakers whose relative positions with respect to the electronic piano are designated in advance. Therefore, it is possible to assign each performance part to the optimal speaker according to the combination of the selected performance parts without bothering the performer's hands. The sense of depth can be simulated more realistically.

  In addition, according to the present embodiment, the performance part assignment priority is set for each external speaker, and the musical sound signal of each performance part is assigned to each external speaker in order of priority, so that each performance part to each external speaker is assigned. Can be automatically optimized.
