Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument that automatically performs a performance based on performance data stored in a memory.

[0002]

2. Description of the Related Art Conventionally, as an electronic musical instrument as described above, there is an electronic musical instrument having a built-in sequencer, for example. In this type of electronic musical instrument, performance data composed of musical tone information such as key code as pitch information and tone color number as tone color information is used, and such performance data is used by, for example, keyboard performance or panel switch operation. Input and store in the memory, this performance data is read sequentially by the operation of the sequencer,
An automatic performance is performed by sending a musical tone to the sound source section.

Among the electronic musical instruments having such an automatic performance function, MIDI (Musical In Musical Instrument) is one of the electronic musical instruments.
(Strument Digital Interface) In some cases, different tones are set for each channel, so that an ensemble automatic performance with multiple parts can be performed.

[0004]

In an electronic musical instrument that performs automatic performance in this way, of the characteristics of the generated musical sounds,
For example, timbres are coded numerically as timbre program numbers, pitches are coded numerically as key codes, and performance intensity information such as touches are also coded numerically.These codes are communicated or recorded as performance data. Or played. Depending on the type of electronic musical instrument such as an electronic organ, an electronic piano, a synthesizer, a portable keyboard, etc., the same program number does not show the same tone color, the same key code does not have the same pitch, and the same touch value does not affect the sensitivity. Due to the difference, the volume may not be the same.

[0005] For this reason, different types of electronic musical instruments are connected using MIDI, and the roles of the sequencer and the sound source are shared so that automatic performances can be performed. Performance data created by other electronic musical instruments or computers can be used. When performing an automatic performance using such an instrument, the tone and volume pitch were different from the original ones.

In other words, a bass tone is supposed to be played with a piano tone, and in a worst case, a saxophone tone is supposed to play a beautiful melody, and a drum tone is apt to be played. Also, even if they are luckily played with the same tone, the performance that should gradually crescend broadly is not so broadly crescendoed and does not become dynamic. As a result, the melody became inconspicuous and caused problems.

An object of the present invention is to obtain an electronic musical instrument having high compatibility with performance data created by different types of electronic musical instruments and the like.

When performing this automatic performance, first a sequencer switch (not shown) is turned on, and then a music number is input. Then, when the start switch 13 is turned on, the automatic performance is started.

The sequencer start process shown in FIG. 18 is started when an ON event of the start switch 13 occurs. First, in step S81, the music number of the currently set sequencer is stored in the register SN.
To prepare for reading the header of the music number SN, and then proceed to step S83.

In step S83, the header of the music number SN is read, the read address of the performance data, the initial tempo, the number of beats, etc. are set, and the config number recorded in the header is stored in the register CN to start reproduction. Preparations are made, and the configuration number CN is set in step S84.
Is determined.

If CN = 4 in step S84, the process proceeds to step S86. If CN = 4, the configuration table is read from the beginning of the performance data in step S85 and RA
The data is written in the area of the configuration table 4 of M7 and the process proceeds to step S86.

At step S86, the timbre number PM _CN (SPi) is read out to the register TC (i) based on the program change number SPCi of the channel number i at the start of the automatic performance and the configuration table corresponding to the configuration number CN. Set, each MID of channel number i
Set the tone for the I channel. When CN = 1 to 3, the configuration tables 1 to 3 of the ROM 6 are used, and when CN = 4, the configuration table 4 of the RAM 7 is used.

When the above process is completed, the flag RUN is set to "1" in a step S87, and the process returns to the main routine.

By the sequencer start processing described above, the RU
Since N = 1, the automatic performance of the music number SN is started by the sequencer processing in step S7 of the main routine.
In the sequencer process of step S7, the performance data is converted by the currently selected configuration table in the same manner as in the MIDI buffer process, and the automatic performance is performed.

Although the automatic performance device of the above embodiment is incorporated in an electronic musical instrument having a keyboard, it may be incorporated in an electronic musical instrument having other performance operators, or a sound source having no performance operators. It may be incorporated in the device.

Further, in the above embodiment, when the performance data is input from the MIDI interface, the config number is input from the panel switch. However, for example, the determination process of the event contents of the MIDI buffer process of FIG. If the processing such as reading the config number from the MIDI buffer is performed in other processing, the electronic musical instrument connected to the MIDI interface can be used to transmit the config number in advance.

In such a case, if the configuration table corresponding to the received configuration number is not stored in the ROM, the data of the configuration table is transmitted from the electronic musical instrument connected to the MIDI interface, and the configuration number is set to “4”. And setting the received configuration table in the configuration table area of the RAM.
