[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an example of a performance practice process of an electronic musical instrument according to an embodiment of the present invention. This electronic musical instrument has a minus one function. The minus one function automatically performs a part (for example, an accompaniment part) of a plurality of performance parts (tracks) excluding a practice part (for example, a melody part). For example, the melody part is not automatically played, and only the accompaniment part is automatically played. The player can practice playing the melody part by operating the keyboard in accordance with the automatic performance of the accompaniment part. At this time, if the performer performs a performance different from the performance data, a different tone is generated to notify the performer of an error. When the performer performs correctly, he or she will sound with a regular tone.
[0010]
The performance data MY1 is stored in the storage means of the electronic musical instrument and is, for example, performance data of a melody part. The performance data MY1 includes performance data 101 to 103. The note-on timing range RNG is a predetermined range including the note-on timing of the performance data MY1. Note-on corresponds to a key press operation. The performance operation information MY2 is performance operation information of a player's keyboard. The performance operation information MY2 has performance operation information 111, 112 and 113 in order.
[0011]
First, performance operation information 111 is generated by a player's operation. The performance operation information 111 has a pitch of “do”, and the corresponding performance data 101 also has a pitch of “do”. The performance operation information 111 has a pitch corresponding to the pitch of the corresponding performance data 101, and its note-on timing is within the note-on timing range RNG. The performance operation information 111 is generated with a regular first tone (for example, a piano tone) because the pitch and note-on timing are appropriate for the performance data 101.
[0012]
Next, performance operation information 112 is generated by the player's operation. The performance operation information 112 has a pitch of “do”, and the corresponding performance data 102 also has a pitch of “do”. In the performance operation information 112, the pitch matches the pitch of the corresponding performance data 102, but the note-on timing is not within the note-on timing range RNG. The performance operation information 112 has an appropriate pitch with respect to the performance data 102, but does not have an appropriate note-on timing, so that the performance operation information 112 is produced in a second tone (for example, a violin tone) different from the normal first tone. .
[0013]
Next, performance operation information 113 is generated by the player's operation. The performance operation information 113 has a pitch of “do”, and the corresponding performance data 103 has a pitch of “re”. In the performance operation information 113, the note-on timing is within the note-on timing range RNG, but the pitch does not match the pitch of the corresponding performance data 103. In the performance operation information 113, the note-on timing is appropriate for the performance data 103, but the pitch is not appropriate, so that the performance operation information 113 is generated in a second timbre different from the normal first timbre.
[0014]
FIG. 2 is an external view of the panel switch 200 of the electronic musical instrument according to the present embodiment. The panel switch 200 has a minus one performance switch 201, a checker switch 202, a start / stop switch 203, a music selection switch 204, and a timbre selection switch 205.
[0015]
The minus one performance switch 201 can switch on / off of the minus one performance. When the minus one performance is on, a part other than the practice part (for example, a melody part) of the completed performance data (song data) is reproduced as described above. When minus one performance is off, the performance data of all parts is played.
[0016]
When the checker switch 202 is ON, the performance played by the player is compared with the performance data of the practice part. If the performance data is the same, the performance is pronounced with a regular first timbre, and if different, the performance is pronounced with a second timbre. When the checker switch 202 is off, the above-described comparison is not performed, and the tone is generated in the first tone color according to the performance operation of the player. The regular first tone color is a tone color specified by performance data, for example, a piano tone color.
[0017]
The start / stop switch 203 can switch start / stop of automatic performance. The automatic performance is a process of reading and reproducing performance data. The music selection switch 204 is a switch for selecting a music to be automatically played.
The tone color selection switch 205 is a switch for selecting a tone color. The first tone color and the second tone color may be designated by the tone color selection switch 205.
[0018]
When the checker switch 202 is turned on, a check mode is set. In the check mode, note-off timing and velocity (strength) can be checked in addition to pitch and note-on timing. The note-off timing and velocity are checked in the same manner as the above-mentioned note-on timing. That is, similarly to the note-on timing range RNG of FIG. 1, a predetermined range including the note-off timing and the velocity of the performance data is set, and if the note-off timing and the velocity by the player's performance operation are within the predetermined range, the range is appropriate. Suppose there is. The note-on timing, the note-off timing, and the velocity are almost always inappropriate if a perfect match is required. Therefore, it is preferable to provide a predetermined range. The more the beginner, the wider the predetermined range needs to be. This predetermined range has a certain range before and after the value of the performance data. Note that the note-off timing need not be checked in order to avoid confusion for beginners. Further, since the note-off timing is the mute timing, when the note-off timing is out of the predetermined range, a new tone generation process is performed with a third tone different from the first and second tone colors.
[0019]
The following two methods are conceivable for the pitch when the check determination is inappropriate. In the first method, the performance operation of the player is respected, and sound is generated at a pitch corresponding to the performance operation of the player. In this case, the determination result can be known from the timbre. The second method uses a fixed interval like a buzzer sound to make mistakes easy to understand.
[0020]
FIG. 3A shows a configuration example of performance data. The performance data includes a plurality of performance data 300 arranged in order. Each performance data 300 has time information 301 and an event 302. The time information 301 indicates the time (the number of clocks) from the previous event 302 to the own event 302. The event 302 includes a note event and the like. The note event includes a note-on event and a note-off event. The time information 301 of the note-on event and the note-off event corresponds to the note-on timing and the note-off timing.
[0021]
FIG. 3B shows a configuration example of the note event 310. The note event 310 has a note command 311, a note number 312, and a velocity 313. The note command 311 is a command indicating a note event.
The note number 312 is a pitch (pitch). The velocity 313 is a strength and corresponds to a volume. When the value of the velocity 313 is 1 to 127, the note event 310 is a note-on event, and when the value is 0, the note event 310 is a note-off event.
[0022]
FIG. 4 is a block diagram illustrating a hardware configuration example of the electronic musical instrument according to the present embodiment. To the bus 400, a CPU 401, a ROM 402, a RAM 403, a flexible disk controller 404, a key scan circuit 406, a panel scan circuit 408, and a sound source (tone generator) 410 are connected.
[0023]
The keyboard 407 has a plurality of white keys and black keys. The key scan circuit 406 outputs performance operation information to the bus 400 in response to a key press operation or a key release operation on the keyboard 407.
[0024]
The panel switch 409 corresponds to the panel switch 200 in FIG. 2, and includes the checker switch 202 and the like. The panel scan circuit 408 supplies operation information to the bus 400 according to the operation of the panel switch 409. The flexible disk drive 405 stores performance data of a plurality of music pieces. The flexible disk controller 404 supplies the performance data of the flexible disk drive 405 to the bus 400. The performance data may be stored in the ROM 402.
[0025]
When the start of the automatic performance is instructed by the start switch 203, the CPU 401 reads out the performance data and outputs the tone parameters to the sound source 410. At this time, when the minus one performance is instructed, the performance data of the parts other than the practice part is read. When the minus one performance is not instructed, the performance data of all parts is read.
[0026]
Further, the CPU 401 generates a note-on event or a note-off event in accordance with the performance operation information of the keyboard 407, compares the performance operation information with the performance data in the check mode, and outputs a predetermined tone parameter to the sound source 410. Output to If the performance operation information is appropriate, the first tone color is set, and if the performance operation information is inappropriate, the second tone color is set.
[0027]
The sound source 410 generates a tone signal based on the tone parameters and outputs the tone signal to the D / A converter 411. The D / A converter 411 converts the tone signal from a digital format to an analog format and outputs it to the amplifier 412. The amplifier 412 amplifies the tone signal and outputs it to the speaker 413. A tone is generated from the speaker 413.
[0028]
The ROM 402 stores performance data, computer programs, and the like. The CPU 401 performs processes and the like in FIGS. 5 to 8 described later according to the computer program. Further, the CPU 401 can perform timing processing according to the time information of the timer 414. The RAM 403 has a work area for the CPU 401 and the like.
[0029]
FIG. 5 is a flowchart illustrating a main routine of a process performed by the electronic musical instrument according to the present embodiment. When the power of the electronic musical instrument is turned on, the following processing is performed. First, in step S501, processing other than steps S502 to S504 described later is performed. Next, in step S502, panel switch processing corresponding to the operation of the panel switch 409 is performed. Details of this processing will be described later with reference to FIG. Next, in step S503, keyboard processing corresponding to the operation of the keyboard 407 is performed. Details of this processing will be described later with reference to FIG. Next, in step S504, a process of reproducing performance data is performed. Details of this processing will be described later with reference to FIG. Thereafter, the process returns to step S501, and the process is repeated.
[0030]
FIG. 6 is a flowchart showing details of the panel switch processing in step S502 of FIG. First, in step S601, the checker switch 202 is processed. When the checker switch 202 is turned on, a check flag is set to indicate the state in the keyboard processing in step S503 in FIG. When the checker switch 202 is turned off, the check flag is cleared. If the check flag is set, it indicates that the mode is the check mode.
[0031]
Next, in step S602, processing other than step S601 is performed. For example, the processing described above is performed according to the operation of the switches 201 and 203 to 205.
[0032]
FIG. 7 is a flowchart showing details of the keyboard processing in step S503 in FIG. First, in step S701, it is checked whether or not a note-on event has occurred due to a key pressing operation of the keyboard 407. If so, the process proceeds to step S702; otherwise, the process proceeds to step S709.
[0033]
In step S702, it is checked whether the mode is the check mode. As shown in FIG. 6, when the checker switch 202 is turned on, a check mode is set. If the mode is the check mode, the process proceeds to step S703. If the mode is not the check mode, the process proceeds to step S706.
[0034]
In step S703, it is checked whether or not the note-on timing of the keyboard depressing operation is within a predetermined note-on timing range RNG (FIG. 1). The note-on timing range RNG is a predetermined range including the note-on timing of the performance data MY1, and is determined in step S802 in FIG. If it is within the note-on timing range RNG, the process proceeds to step S704; otherwise, the process proceeds to step S707.
[0035]
In step S704, it is checked whether the pitch of the key press operation is the same as the regular pitch of the performance data. If they are the same, the process proceeds to step S705, and if they are different, the process proceeds to step S707.
[0036]
In step S705, it is checked whether or not the velocity (strength) of the keyboard pressing operation is within a predetermined velocity range. The predetermined velocity range is a predetermined range including the velocity of the performance data. If the velocity is within the predetermined velocity range, the process proceeds to step S706; otherwise, the process proceeds to step S707.
[0037]
In step S706, the regular first timbre is set as the pronunciation timbre. At this time, the tone color specified by the performance data is set. For example, in the case of performance data of a piano part, the tone color of the piano is set. Thereafter, the process proceeds to step S708.
[0038]
In step S707, a second timbre different from the normal first timbre is set as a sound tone. Thereafter, the process proceeds to step S708.
[0039]
In step S708, the above note-on event is sounded with the sound tone set as described above. That is, a predetermined tone is set and sounded depending on whether or not a key press operation of the keyboard is appropriate. If the performance operation of the player is proper, the sound is produced with a regular first timbre, and if incorrect, the sound is produced with a second timbre. Thereafter, the process proceeds to step S709.
[0040]
In step S709, other processing is performed. For example, if a note-off event has occurred due to a key release operation, processing of the note-off event is performed. That is, a mute process is performed. Thus, the process ends.
[0041]
In addition to the determination of the note-on timing, pitch and velocity, when the note-off timing is out of the predetermined range, a new tone may be newly generated with a third tone different from the first and second tone. .
[0042]
FIG. 8 is a flowchart showing details of the reproduction processing in step S504 in FIG. First, in step S801, it is checked whether the mode is the check mode. If the mode is the check mode, the process proceeds to step S802. If the mode is not the check mode, the process proceeds to step S803.
[0043]
In step S802, a predetermined range is set based on the note event of the practice part of the performance data. That is, the note-on timing range RNG (FIG. 1) is set based on the time information of the note-on event, and the velocity range is set based on the velocity of the note-on event. Further, a note-off timing range is set based on the time information of the note-off event. If the current time position is within the note-on timing range, a note-on timing flag indicating that is set, and if not, the note-on timing flag is cleared. Similarly, a note-off timing flag is set. Based on these flags, the processing of step S703 in FIG. 7 and the like are performed. Thereafter, the process proceeds to step S803.
[0044]
In step S803, it is checked whether the mode is the minus one mode. When the minus one performance switch 201 (FIG. 2) is turned on, the minus one mode is set. If the mode is the minus one mode, the process proceeds to step S804. If the mode is not the minus one mode, the process proceeds to step S805.
[0045]
In step S804, the performance data of all parts other than the practice part is reproduced. In this reproduction processing, the performance data is reproduced and sound generation processing is performed irrespective of the operation of the keyboard and the check result. Thereafter, the process proceeds to step S806.
[0046]
In step S805, the performance data of all parts is reproduced. Thereafter, the process proceeds to step S806.
[0047]
In step S806, other processing is performed. Thus, the process ends.
[0048]
It should be noted that performance operators other than the keyboard may be used instead of the keyboard. The performance operator is used by a player to perform a performance by specifying a pitch, a note-on timing, a velocity, a note-off timing, and the like. Further, the present invention is not limited to the case where the performance check of the melody part is performed as the practice part, and the performance check of the chord of the chord part can also be performed.
[0049]
As described above, according to this embodiment, the performance data including the pitch is stored in the storage means, and the pitch specified by the performance operator and the pitch of the performance data are compared. When both pitches match, the tone generation process is performed with the first tone color, and when they do not match, the tone generation process is performed with the second tone color different from the first tone color.
[0050]
Further, it is determined whether or not the note-on timing specified by the performance operator is within a predetermined range including the note-on timing of the performance data. When the note-on timing is within the predetermined range, the tone generation process is performed with the first tone color, and otherwise, the tone generation process is performed with the second tone color different from the first tone color. The same applies to velocity. Regarding the note-off timing, when it is out of the predetermined range, a new tone generation process is performed with a third tone color different from the first and second tone colors.
[0051]
