TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electronic music apparatus that receives performance information from an electronic musical instrument having a performance operator and a sound source, transmits performance information to the electronic musical instrument, and generates musical tones by a sound source of the electronic musical instrument. And a control program for controlling transmission and reception of the performance information.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in the fields of electronic musical instruments and computer music, for example, a personal computer is connected to an electronic musical instrument, and performance information including MIDI signals is mutually transmitted and received to realize various functions related to performance.
[0003]
For example, performance information when a performance is performed on the electronic musical instrument side is transmitted to a personal computer, and the personal computer analyzes the received performance information and corrects any musically inconvenient parts, and transmits the performance information to the electronic musical instrument side. Is returned, and the electronic musical instrument generates a musical tone based on the returned information. As a result, a performance assisting function can be obtained such that a correct performance can be performed even if a performance error occurs. Also, the performance information is stored in the personal computer in advance, the musical score and the like corresponding to the performance information are viewed and played with the electronic musical instrument, and the performance information at that time is transmitted to the personal computer. Then, the performance information can be obtained by comparing the performance information with a personal computer and grading the performance.
[0004]
FIG. 8 is a diagram schematically showing the above system, in which an electronic musical instrument 20 is connected to a personal computer 10. In any of the above cases, when a performance is performed on the keyboard (performance operator) 20a of the electronic musical instrument 20, performance information corresponding to the performance operation is transmitted from the MIDI OUT to the personal computer 10. Then, the performance information from the personal computer 10 is input to the electronic musical instrument 20 from MIDI IN, and a tone is generated from a sound source 20b of the electronic musical instrument 20. Here, the electronic musical instrument 20 has a switch function called a local control function between the performance operator 20a and the internal sound source 20b, and this switch function can be turned on / off by the electronic musical instrument 20 itself, or can be used for MIDI signals. It is turned on / off by a prescribed message (local on signal / local off signal).
[0005]
When the switch function is turned on (local on state), a normal operation is performed. When the keyboard 20a is operated, a performance corresponding to the operation is performed by the internal sound source 20b. When the switch function is turned off (local off state), even if the keyboard 20a is operated, the electronic musical instrument 20 alone does not sound from the built-in sound source 20b, and the performance information from the keyboard 20a is not output from the MIDI OUT. The sound is transmitted to the personal computer 10 and is sounded by the sound source 20b using only the performance information input from MIDI IN.
[0006]
That is, particularly in the case of the performance assist, if the performance information is directly supplied to the sound source inside the electronic musical instrument, a musical tone due to a performance error is also generated, so that the local off state is set. Note that a sequencer for controlling automatic performance may be used instead of the personal computer 10.

[Problems to be solved by the invention]
Here, as described above, a system that performs performance by transmitting and receiving performance information to and from a personal computer or the like is an electronic musical instrument mainly developed in the form of electronic music such as a synthesizer or a portable keyboard, or has recently become multifunctional. It is applied to an electronic piano or the like, and an electronic organ or the like does not have the local control function. This is because electronic organs were developed mainly for live performance. Electronic organs with three keys, upper and lower keyboards and pedal keyboards, generate musical sounds based on performance information from an external personal computer. This is also because we do not assume that we do. However, it is useful for an electronic organ or the like to realize the functions of the performance assist and the performance training.
[0009]
Therefore, it is conceivable to newly provide a local control function in an electronic organ or the like. However, the number of keyboards is large, the MIDI signal processing needs to be reconstructed, and a large-scale modification is difficult.

For an electronic musical instrument without the function, the volume of the musical tone of the performance information based on the performance operation of the performance operator based on the second performance information is used. Back to.
[0013]
The electronic musical instrument according to the third aspect has no local control function, transmits performance information based on the performance operation of the performance operator to the electronic music device, and corrects the electronic music device according to a predetermined program and returns the performance information based on the returned performance information. Thus, in an electronic musical instrument that generates a musical tone from a sound source, only the volume of the musical tone of the performance information based on the performance operation of the performance operator is reduced according to the first control information received from the electronic music device.
[0014]

The communication interface (I / F) f exchanges MIDI signals and the like with the external device g. When the block diagram is the personal computer 1, the external device g corresponds to the electronic musical instrument 2 or the electronic musical instrument 20. When the block diagram is the electronic musical instrument 2, the external device g corresponds to the personal computer 1.
[0021]
In the case of the personal computer 1, specific examples of each element are as follows. The storage device d is an HDD (hard disk drive), FDD, CD-ROM (compact disk-read only memory) device, magneto-optical disk (MO) device, digital versatile disk (DVD) device, etc. A program (predetermined program) for assistance or training is stored in the storage device d. That is, the storage device d corresponds to “storage means” in the claims. The operation of the keyboard h is detected by the key press detection circuit i. The display unit j is a liquid crystal display, a CRT display, or the like, and is driven via a display circuit k. Further, the communication with the external device g and the communication network p is performed via the communication interface f.
[0022]
In the case of the electronic musical instrument 2, specific examples of each element are as follows. The keyboard h is a keyboard 2a, and a key press detection circuit i detects a keyboard playing operation. The display unit j is a liquid crystal display or the like provided on the operation panel, and is driven via a display circuit k. The tone generator circuit m is a tone generator 2b which generates a tone signal based on performance information (MIDI signal) generated internally and performance information input from the personal computer 1, and outputs the tone signal to a sound system n such as an amplifier or a speaker. Generates a musical tone.
[0023]
FIG. 4 is a diagram for explaining control information output from the personal computer 1 (PC) by the control program according to the embodiment and the function thereof. The electronic musical instrument 20 (function) having a normal local control function is used for the control information. And a function of the electronic musical instrument 2 having no local control function. As the control information, a system exclusive message (exclusive signal) of the MIDI standard is used, and the personal computer 1 uses a predetermined exclusive signal A, B, C, D signal and a normal local ON signal / Outputs local off signal. Note that the exclusive signal A corresponds to “first control information”, and the exclusive signal B corresponds to “second control information”.
[0024]
The electronic musical instrument 20 ignores or does not substantially recognize the exclusive signal C, but the electronic musical instrument 2 turns on MIDI OUT of performance information by playing the keyboard 2a. In response to the local off signal, the electronic musical instrument 20 performs the normal local control off function, and the electronic musical instrument 2 cannot interpret and ignores it. The electronic musical instrument 20 cannot interpret the exclusive signal A and ignores the exclusive signal A, and the electronic musical instrument 2 sets the volume of the performance information to be transmitted to the sound source 2b out of the performance information of the performance of the keyboard 2a to zero.
[0025]
Although the electronic musical instrument 20 ignores or does not substantially recognize the exclusive signal D, the electronic musical instrument 2 turns off the MIDI OUT of the performance information by playing the keyboard 2a. In response to the local ON signal, the electronic musical instrument 20 performs the normal local control ON function, and the electronic musical instrument 2 cannot interpret and ignores it. The electronic musical instrument 20 cannot interpret the exclusive signal B and ignores the exclusive signal B, and the electronic musical instrument 2 returns the volume of the performance information to be transmitted to the sound source 2b among the performance information of the performance of the keyboard 2a.
