DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument capable of executing a performance support function such as a so-called key press guide for each part, a performance support function switching method for efficiently switching the parts, and a performance support function. The present invention relates to a medium storing a switching program.

[0002]

2. Description of the Related Art Electronic musical instruments having a performance support function such as a key press guide have been put to practical use so that even beginners can play music. The key press guide function reads the song data stored in the internal memory or cartridge and determines which key to turn on to play this song by using the LED provided for each key. This is a function that lights up and gives instructions to the player. The music data is stored by being divided into a right hand part, a left hand part, and other parts, and the electronic musical instrument can perform a key pressing guide for only the right hand part or the left hand part, or for both hand parts. In this case, the part that does not guide the key press is automatically played. Normally, the key press guide and the automatic performance are executed alternatively, so in the key press guide mode, the automatic performance is turned off when the key press guide of the right hand (left hand) part is turned on, and the automatic performance is turned off when the key press guide is turned off. The performance is turned on.

[0003]

In a conventional electronic musical instrument,
In the key press guide mode, the key press guide is executed by turning off the automatic performance of the part that the user wants to practice. Therefore, a switch operation for selecting a part is required in addition to a switch operation for entering the key press guide mode. Further, even if the key-depressing guide mode is turned off, the part for which the automatic performance is turned off remains as it is, so that there is a drawback that the original setting is not returned unless the automatic performance of this part is turned on again.

If the on / off of the key press guide and the on / off of the automatic performance are completely linked, the automatic performance is forcibly turned on when the key press guide is turned off. Intermediate players who want to practice some parts without a key press guide or automatic performance have a disadvantage that it is rather inconvenient.

[0005] The present invention provides an electronic musical instrument, a method for switching performance support functions, and a medium storing the program for switching performance support functions, which facilitate the setting operation of performance support functions such as a key press guide function for beginners and intermediate level players. The purpose is to provide.

When the right-hand part switch 18c and the left-hand part switch 18d are operated during the automatic performance without key-depression guide, the automatic performance of the right-hand part and the left-hand part is turned on / off. When the button 18d is operated, the key press guide is turned on / off simultaneously with turning on / off the automatic performance of the right hand part and the left hand part. Either the automatic performance or the key pressing guide is selectively turned on.

FIGS. 2 and 3 show the guide switch 18.
b, right hand part switch 18c, left hand part switch 1
It is a flowchart for explaining how the automatic performance part and the key press guide part are switched when 8d is turned on. This operation is the same whether the automatic performance (key pressing guide) is being executed or stopped by the play / stop switch 18a.

FIG. 2 is a flowchart showing the operation when the guide switch 18b is turned on. First, it is determined whether the key press guide function is currently on or off (s1). If the key press guide function is currently off, it is determined that the switch operation is for turning on this function, the key press guide of the right hand part is turned on (s2), and the automatic performance of the left hand part is turned on. To turn off the automatic performance of the right hand part (s3). In this state, you can practice the most basic right hand part. That is, the beginner can practice the music only by turning on the guide switch 18b. After this, a part change flag PARTCH for storing that the part of the key press guide has been switched is stored.
G is reset (0) (s4), and the operation ends.

On the other hand, if the key press guide function is on when the guide switch is turned off, it is determined that the switch operation is to turn off this function, and the key press guide function is turned off (s5). PARTCHG is further checked (s6). If PARTCHG is 0, it is determined that the user is a beginner who is practicing only the right hand part, so that the setting of the automatic performance part is restored to the original state (s7), and the operation is terminated. On the other hand, PARTCHG is 1
In the case of, it is determined that the intermediate participant has practiced by switching the guide part from the right-hand part to the left-hand part while the key-depression guide function is on, so that the user can practice with the key-depression guide turned off. Thus, the operation is terminated only by turning off the guide function.

The operation of returning the setting of the automatic performance part in s7 to the original state is usually an operation of turning on the automatic performance of the left and right parts. If the switch is turned off, it may return to the turned off state.

FIG. 3 is a flowchart showing the operation when the right hand part switch 18c or the left hand part switch 18d is turned on. In the following description, a case where the right hand part switch 18c is turned on will be described. When the right hand part switch 18c is turned on, it is determined whether the automatic performance of the right hand part is currently on or off (s10). As described above, the initial setting at the time of turning on the power of the electronic keyboard instrument is such that the automatic performance is on for both the right hand part and the left hand part. When the automatic performance of the right hand part is on, the process proceeds from s10 to s11, and the automatic performance of the right hand part is turned off (s11). On the other hand, if the automatic performance of the right hand part has already been turned off, s
The process proceeds from step 10 to s12 to turn on the automatic performance of the right hand part (s12). After this automatic performance on / off operation,
Proceeding to s13, it is determined whether the key press guide function is currently on (s13). The key press guide function is turned on / off in the operation of FIG. 2 based on the operation of the guide switch 18c.

The key depression guide is turned on / off so as to be opposite to the off state (s15 to s17). That is, if the automatic performance of the right hand part is turned off in the above operation, the key press guide of the right hand part is turned on (s15 → s16), and if the automatic performance of the right hand part is turned on, the key press guide of the right hand part is turned off. (S15 → s17). Since the guide part was switched while the key press guide function was turned on, it was determined that the participant was not a beginner who practiced only the right hand part,
HG is set to 1 (s14), and the routine returns. Thereby, even if the key press guide function is turned off in the operation of FIG.
The automatic performance function does not return for this part. In this description, only the case where the right-hand part switch 18c is turned on is described. However, when the left-hand part switch 18d is turned on, exactly the same operation is executed except that the left and right parts are different.

In the above operation, even if the part to be automatically played is changed by the right-hand part switch 18c or the left-hand part switch 18d before the key-depression guide function is turned on, the key-depression guide function is turned on. If the part is not changed, it is determined that the user is a beginner, and the automatic performance of both hands is turned on at the same time as turning off the key press guide function, but before the key press guide function is turned on, If the right-hand part switch 18c or the left-hand part switch 18d is operated, that is, even if the automatic performance part is changed, it is determined that the user is not a beginner, and the key press guide that respects this part selection is turned on / off, and the automatic performance is performed. May be turned on / off. In this case, the operation corresponding to the turning on of the right hand part switch 18c and the left hand part switch 18d may be the one shown in FIG. 3, but when the guide switch 18b is turned on, it operates as shown in FIG.

In FIG. 4, when the guide switch 18b is turned on, it is first determined whether or not the key depression guide function is currently on or off (s20). If the key depressing guide function is currently off, it is determined that the switch has been operated to turn it on, and the following operation is performed to turn on the key depressing guide for the part desired by the player. First, it is determined whether there is a part for which automatic performance is currently turned off (s21). Since the initial setting of this electronic keyboard instrument is automatic performance on both parts, if the automatic performance of some parts is off, it is determined that the user is an intermediate player and the process proceeds to s25. On the other hand, if the automatic performance of all the parts has been turned on, it is determined that the user is a beginner and the process proceeds to s22. s
In the case of 22 or less, the key press guide of the right hand part is turned on (s2
2) The automatic performance of the left hand part is turned on and the automatic performance of the right hand part is turned off (s23). In this state, you can practice the most basic right hand part. That is, the beginner can practice the music only by turning on the guide switch 18b. Then, after that, the part change flag PARTCHG, which stores that the part of the key press guide is switched, is reset (0) (s24), and the operation ends. On the other hand, in s25, the key press guide of the part for which the automatic performance is turned off is turned on, PARTCHG is set to 1 (s26), and the routine returns. This allows you to select a part before turning on the key press guide function,
A manual operation that allows only the key press guide of that part to be executed has been enabled.

On the other hand, if the key press guide function is on when the guide switch is turned off, it is determined that the switch operation is for turning off this function, and the key press guide function is turned off (s27). PARTCHG is further checked (s28). If PARTCHG is 0, it is determined that the user is a beginner who is practicing only the right hand part, so that the setting of the automatic performance part is returned to the original state (s29), and the operation is terminated. On the other hand, when PARTCHG is 1, the practice is performed by switching the guide part from the right-hand part to the left-hand part while the key-depression guide function is turned on, or a desired part is switched before the key-depression guide function is turned on. Is judged to be an intermediate person who has practiced with the automatic performance turned off, so that the operation is ended only by turning off the guide function so that the player can practice with the key pressing guide turned off. The operation of returning the setting of the automatic performance part in s29 to the original state is an operation of turning on the automatic performance of the left and right parts, or one of the left and right parts is turned off before the key pressing guide function is turned on. In this case, any operation of returning to the turned-off state may be used.

In the above-described embodiment, as a performance support function, an LED 19a is provided for each key of the keyboard 16, and a key press guide function for turning on an LED corresponding to a key to be turned on as the music progresses is used.
