Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an electronic musical instrument capable of performing automatic rhythm play and manual rhythm play.

[Prior art and its problems] Conventionally, there has been known an electronic musical instrument which is provided with a pad switch on an electronic musical instrument and which can perform a manual rhythm by pressing the pad switch. In such an electronic musical instrument, when a manual rhythm performance is performed during an automatic rhythm performance, the rhythm sound related to the manual rhythm performance is merely superimposed on the rhythm sound related to the automatic performance, and the manual rhythm performance is not performed. It didn't sound too much. It is also conceivable to start the manual rhythm performance and stop all the rhythm sounds related to the automatic rhythm performance and to emit only the rhythm sounds related to the manual rhythm performance. Is very difficult.

In view of the above circumstances, the applicant has filed Japanese Patent Application No. 60-2331.
No.02 proposed a new electronic musical instrument. When the new electronic musical instrument performs a manual rhythm performance during an automatic rhythm performance, a specific rhythm sound (for example, bass drum) generated in a basic rhythm is excluded from rhythm sounds related to the automatic rhythm performance. All the rhythm sounds are stopped, the rhythm sound relating to the manual rhythm performance and the specific rhythm sound are controlled so as to generate only the manual rhythm sound, and the specific rhythm sound is left. This facilitates the rhythm keeping of the manual rhythm performance.

Here, as described above, by the start of the manual rhythm performance during the automatic rhythm performance, the timing for returning from the state where only the rhythm sound and the specific rhythm sound are generated to the original state is, for example, Musically well-defined timing, such as bar division, can be considered.

However, it is anticipated that there may be cases in which the user performs a manual rhythm performance that causes the return operation to be performed at the above-mentioned timing.

[Purpose of the Invention] The purpose of the invention is to perform the return operation at a timing that is musically well-defined and that has the least possibility of going against the intention of the person performing the manual rhythm performance.

[Gist of the Invention] In order to achieve the above object, the present invention provides a method for performing a manual rhythm performance when an operator related to a manual rhythm performance is operated immediately before a predetermined timing at which the return operation is performed. The point is that it is considered that the performer has continued to indicate that he wants to continue the manual rhythm performance, and the return operation is deferred once.

[Configuration of Embodiment] An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows the overall circuit configuration of an electronic musical instrument. In FIG. 1, reference numeral 1 denotes a switch unit. The switch unit 1 is provided with a cancel switch 2, a start / stop switch 3, a fill-in switch 4, and an accompaniment mode switch 5. ing.

The cancel switch 2 is for stopping the emission of the rhythm sound for each rhythm sound source of the automatic rhythm performance, of which the BD cancel switch 2a is for bass drum sound, and the SN / RIM cancel switch 2b is for snare drum sound. HB / LB / CLP cancel switch 2
c is the hibongo sound, lowbongo sound and clap sound, CY
The HH cancel switch 2d stops the cymbal sound and the hi-hat sound, respectively, and the switches 2a to 2d stop when turned on and emit sound when turned off.

The start / stop switch 3 starts and stops an automatic rhythm performance, and the fill-in switch 4 performs a fill-in performance that changes the contents of the automatic rhythm performance. The accompaniment mode switch 5 switches the accompaniment mode. Of these, the off switch 5a automatically switches all keys to the normal manual mode, and the fingered switch 5b automatically switches all chords while holding down the entire chord configuration. The one-finger switch 5c designates the mode for performing the accompaniment, and the mode for automatically performing the chord accompaniment while holding down one finger.

When each of the pad switches 6a to 6h of the rhythm pad section 6 is pressed, a switching operation is performed, and rhythm sound input information indicating an instruction to emit a single rhythm sound is input. Drum), SN (Snare Drum), RIM (Rim Shot), CLP (Clap), HB (Hi Bongo), LB (Lo Bongo), CY (Cymbal), HH
A sound emission instruction is given for each rhythm sound of (hi-hat). The rhythm performance by the rhythm pad section 6 is possible regardless of whether the cancel switch 2 is on or off. However, a rhythm sound different from the rhythm sound turned off by the cancel switch 2 is produced by the rhythm pad section 6. In this case, in principle, all the automatic rhythm performances other than the bass drum sound and the automatic accompaniment of the bass and chord are stopped, and the rhythm pad section 6 enters the manual fill-in mode in which all the rhythm performances other than the bass drum sound are performed. . In this case, only the bass drum sound is emitted because the bass drum sound is a fundamental sound of all rhythm performances, and is also for understanding the performance tempo.

In the rhythm performance of the manual fill-in mode, when the rhythm pad section 6 is operated after the fourth beat of the bar of this performance, the manual fill-in mode is further continued for one bar, and after the fourth beat. When the rhythm pad section 6 has not been operated, the manual fill-in mode is released at the beginning of the next measure, which is a new measure after this mode is set, and the automatic rhythm performance is resumed.

Also, rhythm pattern information for automatic rhythm performance is stored in the rhythm pattern ROM 7 of FIG. 1, and this rhythm pattern information is read out by the CPU 8 and given to the rhythm sound creation section 9 to give a bass drum sound or the like. Various rhythm sound signals such as a hi-hat sound are generated and output from the speaker 11 via the amplifier 10. Each operation of each of the pad switches 6a to 6h of the rhythm pad section 6 is detected by the CPU 8, and rhythm sound input information indicating an instruction to emit the corresponding rhythm sound is given to the rhythm sound creating section 9, and the rhythm sound is created and emitted. Will be done.

The chord / base pattern ROM 12 stores chord and bass automatic accompaniment pattern information, and the information corresponding to the operation keys of the keyboard 14 is read out by the CPU 8 and given to the musical tone creation section 13. Then, a tone signal of a chord sound and a bass sound is created, and is output from the speaker 11 via the amplifier 10. The operation of each key of the keyboard 14 is detected by the CPU 8, the corresponding pitch information is given to the musical tone creating section 13, and musical tones are created and emitted.

The program memory 15 stores a program for the CPU 8 to perform various control processes, and the working memory 16 stores data necessary for the various control processes.

FIG. 2 shows a specific configuration of the working memory 16. The working memory 16 includes a bar count register PCNT, an accompaniment mode register AFO, a cancel rhythm register CAN, a rhythm mode register M, and a continuation flag register CONT. Each is provided. Among them, the bar count register PCNT stores 0 to 0 at a speed corresponding to the set tempo.
Counting for one bar is performed in the range of 47, and the timing of the range from 45 to 47 after the back of the fourth beat automatically returns to 0 when the count reaches 47. The accompaniment mode register AFO stores the mode of whether the accompaniment mode set by the accompaniment mode switch 5 is fingered to one-finger, and the rhythm start and fill-in modes by operating the start / stop switch 3 and the fill-in switch 4. Is stored, and "1" is set in the corresponding bit. Cancel rhythm register CAN
Stores which rhythm sound is canceled by turning on each of the cancel switches 2, and "1" is set to the corresponding bit. The rhythm mode register M stores the content of the current rhythm performance
A distinction is stored between a manual fill-in mode (which is "1" at this time) by operating only the rhythm pad section 6 and a normal mode (which is "0" at this time) in which automatic rhythm performance is performed. A flag is set in the continuation flag register CONT when the manual fill-in mode is further continued for one bar.

[Operation of Embodiment] Next, the operation of this embodiment will be described.

<Overall Processing> The CPU 8 starts the main flow processing of FIG. 3 when the power is turned on. That is, the CPU 8 performs the initial setting of the working memory 16 and the like (step G1), scans each key of the keyboard 14 and changes the scanning key (steps G2 and G3). The melody key code or the accompaniment key code is created and given to the musical tone creating unit 13, and the tone generation or the silencing process is performed (step G4).

Next, each switch of the switch unit 1 is scanned, and if there is a change in the operation switch (steps G5 and G6), a switch process corresponding to the change of the switch is performed (step G7). Each pad switch
If there is a change after scanning 6a to 6h (steps G8 and G9), a rhythm pad process for emitting a corresponding rhythm sound or changing a rhythm performance mode is performed (step G10).

Finally, if the start / stop switch 3 is turned on and "1" is set in the MSB (most significant bit) of the accompaniment mode register AFO, rhythm performance processing for performing automatic rhythm performance and the like is performed (steps G11 and G12). Thereafter, the processing of these steps G3 to G12 is repeated.

<Automatic Rhythm Performance Process> Next, in order to start the automatic rhythm performance, the start / stop switch 3 may be turned on first. Then CPU8
In the processing of FIG. 4 which is a subroutine of the switch processing of step G7 of FIG. 3, the start / stop switch 3 is detected to be on (step B1), and the MSB (most significant bit) of the accompaniment mode register AFO is determined. Reverse the mode to the automatic rhythm performance mode (step B2). And, since none of the cancel switches 2a to 2d are turned on,
The cancel rhythm setting process of steps B9 to B16 described later is not performed.

In this case, if the fill-in switch 4, fingered switch 5b, and one-finger switch 5c are also turned on (steps B3, B5, B7), the fifth, seventh, and sixth bits of the accompaniment mode register AFO are inverted, respectively. During fill-in, one-finger and fingered modes are set (steps B4, B6, B8).

Subsequently, the CPU 8 reads the rhythm pattern information from the rhythm pattern ROM 7 in the process of FIG. 6 which is a subroutine of the rhythm performance process of step G12 of FIG.
If the mode is one-finger or fingered, the accompaniment pattern information is also read (step D1), BD (bass drum), SN (snare drum), RIM (rim shot), C
LP (crap), HB (hibongo), LB (lobongo,
For each rhythm sound of CY (cymbals) and HH (hi-hat), it is determined that none has been canceled and "1" is not set in the corresponding bit of the cancel rhythm register CAN (steps D2, D6, D9, D12). , D15, D18, D21,
D24), if each is the sounding timing (steps D3, D7, D10, D13, D16, D19, D22, D25), the sounding instruction data of the rhythm sound is sent to the rhythm sound creating section 9, and
Produce the rhythm sound (steps D4, D8, D11, D1
4, D17, D20, D23, D26). Next, if it is the sounding timing of each of the bass sound and the chord sound (steps D27 and D29), each key code and the like of the bass sound and the chord sound are sent to the musical sound creation unit 13, and the bass sound and the chord sound are transmitted. A chord sound is generated (steps D28 and D30).

In this case, after the sound processing of the BD (bass drum) sound in step D4, the CPU 8 determines whether or not the rhythm mode register M is "0" (step D5). Since it is "0" in the normal mode, the automatic rhythm performance processing and the automatic accompaniment processing in steps D6 to D30 described above are performed. And CPU8
Finally, the bar count register PCNT is incremented by one (step D31). The processing after step D32 will be described later.

<Rhythm pad performance processing of cancel rhythm> Next, among the above-mentioned automatic rhythm performance sounds, the operator can perform only the rhythm sound of SN (snare drum) and RIM (rim shot) by pressing the cancel switch. 2
Then, the SN / RIM cancel switch 2b may be turned on. Then, in the process of FIG. 4 which is a subroutine of the switch process in step G7 of FIG.
Determine whether the M cancel switch 2b is on (step B1
1), "1" is set to the 6th and 7th bits of the cancel rhythm register CAN, SN (snare drum) and RIM
The rhythm cancel of (rim shot) is stored (step B12).

Thereby, in the rhythm performance processing of FIG.
Only in steps D6 and D9, it is determined that the corresponding bit of the cancel rhythm register CAN is "1", and the rhythm sound generation processing in steps D7, D8, D10, and D11 is not performed, and the snare drum sound is not generated. The rim shot sound has no automatic rhythm performance. In this case, the rhythm sound of other bass drums, claps, hibongos, lobongos, cymbals, and hi-hats will continue to be played automatically. Next, the switching operation is performed by pressing the pad switch 6b or 6c of SN (snare drum) or RIM (rim shot). Then, in the process of FIG. 5, which is the rhythm pad process of step G11 of FIG. 3, the CPU 8 detects that the pad switches 6b, 6c are turned on (step C1), and turns on the turned on pad switches 6b, 6c. Is transmitted to the rhythm sound creation section 9 to cause the rhythm sound of the snare drum or the rim shot to sound (step C2).
Then, it is determined whether or not the bit corresponding to the snare drum or the rim shot of the cancel rhythm register CAN is "1" (step C3).
Since "1" is set in 2 and the state is in the cancel state, the rhythm pad processing is terminated without performing the subsequent processing.

Thus, the automatic rhythm performance is stopped only for a specific rhythm sound source among the automatic rhythm performances, and the operator can perform the rhythm performance in a free pattern.

In this case, to stop the automatic rhythm performance for other rhythm sounds and perform the manual rhythm performance, turn on the corresponding cancel switches 2a, 2c, 2d and operate the pad switches 6a, 6d to 6h. I just need. Then, when the cancel switch 2 is turned on, "1" is set in the corresponding bit of the cancel rhythm register CAN.
D13, D14, D16, D17, D19, D20, D22, D23, D25, D26)
Is not performed (steps D12, D15, D18, D21, D2
4) A manual rhythm performance of a free pattern is performed by turning on the rhythm pad section 6 (steps C1 to C3).

<Rhythm performance processing in manual fill-in mode> Further, all automatic rhythm performances other than bass drum sounds and automatic accompaniment of bass and chords are stopped, and a manual fill-in mode is performed in which all rhythm performances are performed only by the rhythm pad section 6. In this case, the pad switches 6a to 6h in which the cancel switches 2a to 2d are not turned on may be turned on.
Then, the CPU 8 performs the sound processing of the pad rhythm sound in steps C1 and C2 (steps C1 and C2), and determines whether the bit of the rhythm sound corresponding to the operation pad of the cancel rhythm register CAN is "1". (Step C
3). In this case, since the pad switches 6a to 6h in which the cancel switches 2a to 2d are not turned on have been turned on, the corresponding bit is "0", and the CPU 8 proceeds to step C4 and sets the rhythm mode register M to "0". Is determined (step C4).

Since it was "0" in normal mode as it was, CP
U8 proceeds to step C5, sets "1" in the rhythm mode register M, and sets the manual fill-in mode (step C5).

As a result, the register M becomes "1" in the rhythm performance processing of FIG. 6 (step D5), so that the subsequent automatic rhythm performance processing and automatic accompaniment processing of steps D6 to D30 are not performed. Can perform all rhythm performances.

<Continuation of Manual Fill-in Mode> In order to continue the manual fill-in mode, the pad switches 6a to 6h are turned on after the fourth beat of the bar of the rhythm performance in this mode. Then, the CPU 8 performs the sound processing of the pad rhythm sound in the steps C1 to C3 (steps C1 to C3), and then determines whether or not the rhythm mode register M is "0" (step C4).

In the future, since the value is set to "1" in the manual fill-in mode, the CPU 8 proceeds to step C6, and determines whether or not the current timing at which the pad switches 6a to 6h are operated is "45" or later in the bar count register PCNT. Is determined (step C6). Since the operation timing is between "45 and 47" after the fourth beat, the CPU 8 proceeds to step C7 and sets "1" in the continuation flag register CONT (step C7).

As a result, the manual fill-in mode becomes one more.
It is stored that the measure is continued.

Even during this manual fill-in mode, the counting process of the bar count register PCNT in step D31 described above is continued, and at the beginning of the next bar that is a new bar break after the manual fill-in mode is set, the register PCNT is reset to `` Therefore, the CPU 8 determines this in step D32 (step D32), and determines whether the continuation flag register CONT is "1" (step D32).
D33). Since the flag CONT has already been set to "1" in step C7, the CPU 8 proceeds to step D35, in which the rhythm mode register is set to "1", that is, the mode is set to the manual fill-in mode. Clear CONT (step D35).

Thus, the manual fill-in mode in which all rhythm performances are performed only by the rhythm pad section 6 can be continued for one bar.

<Manual Fill-in Mode Release Processing> To release the manual fill-in mode, the pad switches 6a to 6h are not turned on after the fourth beat of the bar of the rhythm performance in this mode. Then, the process of setting “1” to the continuation flag register CONT in step C7 is not performed.

Then, when the beginning of the next measure serving as a new measure delimiter after setting the manual fill-in mode is reached and the measure count register PCNT becomes "0" (step D32), the continuation flag register also becomes "1". It is determined whether or not there is (step D33). However, since “1” is not set in the future, the CPU 8 proceeds to step D34, and sets the rhythm mode register M in which “1” is set.
To "0" to release the manual fill-in mode and return to the normal mode (steps D33, D3
Four).

In this way, it is possible to automatically return from the manual fill-in mode in which all rhythm performances are performed only by the rhythm pad section to the normal mode in which automatic rhythm performance is performed, and the pad switches 6a to 6h are operated according to the operation timing of the pad switches 6a to 6h. You can freely select the length of the rhythm performance of the manual that performs all the rhythms in only 6h.

In the present embodiment, the method of stopping the emission of the automatic rhythm performance sound is such that the rhythm pattern information is not transmitted to the rhythm sound creation unit 9 even if the rhythm pattern information is read (step D1) (steps D6, D9, etc.). ), A form that does not read the rhythm pattern information itself, or a cancel switch
For example, canceling only the rhythm sound selected in 2a to 2d and entering the manual fill-in mode, any sound emission stop mode may be used, regardless of whether the cancel switches 2a to 2d are on or off. When the pad switches 6a to 6h are operated, the sound is stopped, such as canceling immediately to enter the manual fill-in mode, or immediately turning on the cancel switches 2a to 2d to enter the manual fill-in mode. The instruction form may be of any type, and the manual rhythm performance instructing means may be a keyboard 14 in addition to the rhythm pad section 6, or may be a striking type other than a pressing type, or may be from an externally connected device. Alternatively, the rhythm pad section 6 itself may be detachable from the main body of the electronic musical instrument. The number of a to 6h may be one, and the type of rhythm sound that can be input may be made selectable by the cancel switches 2a to 2d. The input form and structure may be of any type. May be determined not only after the back of the bar but also at other timings, and the restoring means may control the timing of restoring other than a bar break. The same is true, and the present invention is not limited to the above embodiment.

[Effects of the Invention] In the present invention, in a state where only the rhythm sound related to the manual rhythm and the specific rhythm sound related to the automatic rhythm performance are generated by the start of the manual rhythm performance during the automatic rhythm performance, the state is changed. When returning to the original state, the timing for performing the return operation is changed to the timing for performing the manual rhythm performance when the operator related to the manual rhythm performance is operated immediately before the predetermined timing at which the return operation is performed. Is considered to have continued to indicate that he / she wants to continue the manual rhythm performance, and is deferred once. Therefore, the return operation is musically well-defined and the manual rhythm performance is performed. It can be performed at a timing with the least possibility of going against the will of the person.
