Description

[Detailed description of the invention] This invention relates to an automatic performance device suitable for use in performance practice, etc. By recording different music information related to a given song on separate recording media and playing it back as appropriate, the device can provide a variety of information for each song. This allows for automatic performance.

2. Description of the Related Art Conventionally, an automatic performance device has been proposed in which different musical information such as a melody, obbligato, and auto-bass chord regarding a predetermined musical piece is magnetically recorded on a single score sheet and then played back as appropriate.

However, for such devices, 1
Because there is a limit to the recording capacity of the magnetic tape attached to a sheet of musical score, if a song becomes long or has many parts, it may not be possible to record all the necessary musical information. Notes (pitch/note length), not as information (chord name)
There were drawbacks such as the inability to record information.

The purpose of this invention is to provide a new automatic performance device that eliminates these drawbacks.

The automatic performance device according to this invention is compatible with (a) a plurality of N recording media each recording different music information related to a predetermined song, and (b) a recording capacity of a plurality of M minutes, which is less than the total number N of these recording media. (c) reading means for reading music information from M or less recording media arbitrarily selected from the plurality of N recording media and storing it in the storage device; d) Automatic performance means for performing automatic performance based on the music information stored in the storage device.

According to the structure of this invention, even if the types of music information to be recorded increase, the number of recording media can be increased accordingly, thereby preventing a situation where the recording capacity becomes insufficient. I can do it.

In addition, as a storage device, one having a storage capacity corresponding to a recording capacity of a plurality of M, which is less than the total number of N recording media, is used, and the number of recording media that is arbitrarily selected from among the plurality of N recording media is within M. Since the music information read from the computer is stored in the storage device for automatic performance, even with a small storage capacity, you can change the selection combination of recording media or increase the number of recording media to create a wide variety of automatic performances. It becomes possible to perform.

This invention will be described in detail below with reference to embodiments shown in the accompanying drawings.

FIG. 1 shows a musical score sheet as a recording medium used in an automatic performance device according to an embodiment of this invention, where 10A, 10B, 10C, etc. are a melody musical score sheet and an obbligato musical sheet for the same song, respectively. , bass music sheet...
...is... These musical score sheets 10A, 10B,
10C... is generally indicated by the reference numeral 10. Each musical score sheet 10 has a musical score printed on its surface, and a magnetic tape 12 is attached near the lower end of the surface, and the magnetic tape 12 has part type identification information. data, timbre/effect control data, and musical note (pitch and note length) data are recorded. That is,
On the score sheet 10A, data corresponding to the melody score on the front side is recorded as data ~, on the score sheet 10B, data corresponding to the obbligato score on the front side is recorded as data ~, and on the score sheet 10C, data ~ is recorded as data ~. The sheet music corresponding to the bass sheet music on the front side is recorded, and the same is true for other sheet music sheets.

Different music information regarding one song is as follows:
In addition to recording by part, you can also record melody variations, the same melody but with different tones, etc. For example, musical score sheets 10A, 10
B, 10C... for normal melody, respectively.
For normal obbligato, for normal base...
Then, the corresponding musical score sheets 10A′,
10B', 10C'... for melody variations and obbligato variations, respectively.
It is a good idea to prepare a base variation... so that you can select and use any one for each part.

FIG. 2 shows an example of the configuration of an automatic performance device, in which musical score sheets 10 are placed one by one by a data reading device 1.
4, and the recorded data is read. The read data is then supplied to the data discrimination circuit 16.

Assuming that the data on the melody score sheet 10A is read first, the data discrimination circuit 16 discriminates that it is melody data based on the part type discrimination data, and transfers the melody tone/effect control data to the control data register 18. Write to melody register. Further, upon receiving the melody note data, the data discrimination circuit 16 causes the data write control circuit 20 to start a data write operation. That is, the data write control circuit 20 puts the melody counter of the address counter 22 and the note data memory 24 consisting of RAM (random access memory) into the write mode, so that the memory 24
Melody note data from the data discrimination circuit 16 is written into. At this time, the first address memory 26
In the melody storage section, head address data indicating the first write address of melody note data is written.

Next, assuming that the data of the obbligato score sheet 10B is read, the obbligato register of the control register 18 stores the obbligato tone/effect control data, and the memory 24 stores the obbligato note data in the same manner as described above. Head address data regarding obbligato note data is written in the obbligato storage section of the memory 26, respectively.

Next, assuming that the data of the bass score sheet 10C is read, the bass register of the control register 18 stores the bass tone/effect control data, and the memory 24 stores the bass note data, in the same manner as described above. Head address data regarding the base note data is written in the base storage section of the memory 26, respectively. Note that even when music information regarding other parts is read, the data writing operation for each part is performed in the same manner as described above.

As a result of the above, note data is written into the memory 24 in the order of melody, obbligato, bass, etc. However, it is not necessarily necessary to write the data of all parts to the memory 24, and it is not necessary to write the data of all parts to the memory 24. Data can also be selectively loaded into memory 24. In addition, as mentioned above, the normal score sheets 10A, 10B, 10
C...In addition to this, there are 10 sheet music sheets for variations.
When A', 10B', 10C'... are prepared,
10A or 10A', 10B or 10B', 10C
Or 10C'...The recorded data of one score sheet selected for each part is stored in the memory 24.
can be loaded into. That is, memory 2
4 has a storage capacity corresponding to the recording capacity of five magnetic tapes (five parts) as shown in FIG. Recorded data of musical score sheets can be loaded.

Thereafter, to start automatic performance, the mode selection switch included in the mode selection switch circuit 28 is operated to designate the part to be played.

For example, if a melody part is specified, the melody readout control section of the readout control circuit 30 and the melody sound formation section of the musical tone formation circuit 32 start their respective operations in response to the melody part specification signal from the mode selection switch circuit 28. do. That is,
The melody read control section of the read control circuit 30 reads out the start address data related to the melody from the start address memory 26 and loads it into the melody counter of the address counter 22, so that the pitch data corresponding to the first melody sound is read from the memory 24. is read out and supplied to the melody tone forming section of the musical tone forming circuit 32. Therefore, the melody sound forming section generates the first melody sound signal according to the first pitch data and the melody tone/effect control data from the control data register 18, and this melody sound signal is sent to the output amplifier 34. The signal is supplied to the speaker 36 via the signal. Therefore, the first melody sound is produced from the speaker 36.

Further, since the first pitch data from the memory 24 is supplied to the pressed key display device 38, the pressed key display device 38 visually displays the key to be pressed first.

Upon reading out the first pitch data from the memory 24, the melody counter of the address counter 22 receives a read command signal from the melody read control section of the read control circuit 30 and increments by one count. Therefore, the first note length data is read from the memory 24 and supplied to the melody read control section.

The melody read control unit counts the tempo clock signal TCL from the tempo oscillator 40 and supplies a read command signal for the next melody sound to the address counter 22 when the time point corresponding to the note length indicated by the first note length data is reached. do. Therefore, the melody counter of the address counter 22 increments by one count, and the pitch data corresponding to the second melody tone is read out from the memory 24. As a result, the second melody tone is played and the second key press is displayed as in the previous time. The above-described melody note data reading operation is repeated in the same manner, thereby automatically performing the melody and displaying the pressed keys.

The above is the operation when the melody part is selected, but the memory 2
4, the note data of the selected part is read out, and automatic performance and automatic key press display are performed based on the read data. In addition, when two or more parts of melody, obbligato, and bass are selected at the same time, the note data of the selected multiple parts are read out in parallel from the memory 24, and the musical tone forming circuit 32 reads out the note data of the selected parts. Since the musical tone forming sections of the plurality of parts each form a musical tone signal, the musical tones of different parts are produced from the speaker 36 at the same time.

Note that since the autorhythm device 42 automatically generates a rhythm sound signal based on the tempo clock signal TCL and supplies it to the output amplifier 34, the autorhythm sound is also produced from the speaker 36.

As described above, according to this invention, different music information regarding one song is recorded on a plurality of recording media and played back as appropriate, so that the following excellent effects can be obtained.

(1) Long songs or songs with many parts can be easily handled by increasing the number of recording media.

(2) Base information can be recorded as note information.

(3) You can select the part you want to practice and load it into memory.

(3) Even if a memory 24 with a small storage capacity is used, it is possible to enjoy a wide variety of automatic performances by changing the selected combination of recording media or increasing the number of recording media. For example, as mentioned above, the storage capacity of the memory 24 is made to correspond to the recording capacity of 5 parts, and the musical score sheet 10 is a normal sheet 10A.
~10E and variation 10
If a total of 6 pieces of A' are used, 10
In addition to automatic performance using the recorded data of A to 10E, automatic performance using the recorded data of 10A' and 10B to 10E is possible.
By increasing the variations like B' to 10E', even more diverse automatic performances are possible.
