[0016]
The display 13 is composed of a liquid crystal display, a CRT, or the like, and displays characters, numbers, figures, and the like. The display content of the display 13 is controlled by a display control circuit 17 connected to the bus 20. The tone signal generation circuit 14 is connected to the bus 20 and generates a tone signal based on performance data supplied under the control of a CPU 31 described later. The generated musical sound signal includes a melody sound signal and accompaniment sound signals such as a chord signal and an arpeggio sound signal. The tone color and volume of these tone signals are also controlled by tone control data supplied from the CPU 31.

It is what is done.
[0019]
As shown in FIG. 4, the arpeggio data includes a plurality of types of sound pattern data 1 to N corresponding to a plurality of types 1 to N, respectively, and a header. Each sounding pattern data includes a series of sounding event data for controlling the sounding of arpeggio sounds, as shown in FIGS. 5 (A) and 6 (A). Each sounding event data includes timing data, gate time data, key data (pitch name designation data), octave data, and velocity data.
[0020]
The timing data represents the time from the start of the performance based on the pronunciation pattern data. This time is represented by the number of clocks in which one beat (quarter note length) is 480 clocks. The gate time data represents the gate time of the arpeggio sound (corresponding to the key-on time) by the same number of clocks as described above. The key data designates a specific sound among a plurality of performance sounds. In the case of this embodiment, the key data represents the order of the performance sounds from the low sound side. Instead of this, the order of the performance sound from the high sound side may be represented. Octave data represents the octave change of the specified specific sound. Specifically, “+0” indicates that the performance sound itself is an arpeggio sound, “+1” and “+2” indicate that the performance sound is raised by one octave and two octaves, respectively, and becomes an arpeggio sound. "-1" and "-2" indicate that the performance sound is lowered by 1 octave and 2 octaves, respectively, to be an arpeggio sound. Velocity represents the volume of the arpeggio sound.
[0021]
The header represents the correspondence between the tone color of the arpeggio sound and the pronunciation pattern data 1 to N. For example, sound pattern data 1 to 10 correspond to tone color A, and sound pattern data 11 to 20 correspond to sound color B.
[0022]
As shown in FIG. 7, the switching control data includes a plurality of switching timing data respectively corresponding to a plurality of timbres of an arpeggio sound. The switching timing data is used to end the generation of the arpeggio sound signal in response to the instruction to end the generation of the arpeggio sound and the timing to change from the currently used sounding pattern to the new sounding pattern in response to the instruction to change the sounding pattern. Represents timing. This switching timing data is, for example, data specifying the end of every predetermined number of bars (for example, the end of every 1 or 2 bars), the end of every predetermined number of beats (for example, the end of every 1, 2 or 3 beats) ). In addition, this switching timing data may indicate that the timing of the switching and generation end is not specified, that is, that the switching of the sound generation pattern and the end of generation of the arpeggio sound are allowed at any time (in FIG. ").
[0023]
The communication interface circuit 36 can be connected to an external device 41 such as another electronic musical instrument or a personal computer, and the electronic musical instrument can communicate various programs and data with the external device 41. A performance device such as a keyboard may be adopted as the external device 41, and performance information may be input from the external device 41 instead of or in addition to the performance by the performance operator group 11. Further, the communication interface circuit 36 can be connected to the outside via a communication network 42 such as the Internet, so that the electronic musical instrument can receive various programs and data from the outside, or can transmit to the outside. ing.
[0024]
Next, the operation of the embodiment configured as described above will be described. First, the general operation of the electronic musical instrument will be described. First, the performer sets the operation mode of the electronic musical instrument by operating the panel operator group 12 in accordance with the display content of the display 13. Specifically, for example, the tone color and volume of performance sounds such as melody sounds and accompaniment sounds, effects added to performance sounds, and the like. In this case, the CPU 31 supplies the musical tone signal generation circuit 14 with musical tone control data representing the set tone color, volume, and effect by executing a program (not shown).
[0025]
Thereafter, when the performer starts playing the music piece by operating the performance operator group 11, the CPU 31 inputs performance data corresponding to the performance from the detection circuit 15 by executing a program (not shown). Are processed or supplied to the musical tone signal generation circuit 14 as performance data for melody and accompaniment sounds. The tone signal generation circuit 14 generates tone signals such as a melody tone signal and an accompaniment tone signal in accordance with the supplied performance data. In this case, the tone color, volume and effect of the tone signal are controlled based on the tone control data previously supplied to the tone signal generation circuit 14. The generated musical sound signal is emitted as a musical sound through the sound system 18.
[0026]
Next, the arpeggio function directly related to the present invention will be described. First, a case will be described in which the player operates an arpeggio-related operator in the panel operator group 12 in a state where the electronic musical instrument is not set to an edit mode for editing data relating to the arpeggio sound. In this case, the CPU 31 starts execution of the arpeggio sound setting program in step S10 of FIG. 2, determines “No” in step S12, executes the processes of steps S14 to S20, and in step S24. Terminates the execution of the arpeggio sound setting program. When the timbre selection operator for selecting the timbre of the arpeggio sound is operated, timbre selection data representing the timbre of the arpeggio sound is set according to the timbre selection operator operated in step S14, and the same setting is made. The timbre selection data is supplied to the tone signal generation circuit 14. After the timbre selection data is set, in step S16, the switching control data is referred to, and timing data representing the sound generation pattern switching timing corresponding to the selected timbre is obtained.
[0027]
When the performer operates the pattern selection operator, the CPU 31 sets pattern selection data for selecting an arpeggio sound generation pattern in accordance with the operated pattern selection operator in step S18. This pattern selection data is specified by the header in the arpeggio data, and designates one of the pronunciation pattern data associated with the selected tone color. For example, when the timbre A is selected, any one of the pronunciation pattern data 1 to 10 is designated. When the timbre B is selected, any one of the pronunciation pattern data 11 to 20 is designated.
[0028]
When the performer operates an arpeggio operator for instructing the start and stop of the automatic arpeggio or an accompaniment operator for instructing the start and stop of the automatic accompaniment including the automatic arpeggio, the CPU 31 executes the process of step S20. In the process of step S20, when the accompaniment operation is instructed to start automatic accompaniment and the arpeggio operation is instructed to start automatic arpeggio operation, the arpeggio sound generation start is instructed. At this time, the operation flag RUN indicating the operation state of the automatic arpeggio is set to “1”. On the other hand, when the automatic accompaniment operation is instructed by the accompaniment operator or the automatic arpeggio operation is instructed by the arpeggio operation unit, the end of generation of the arpeggio sound is instructed. However, the operation flag RUN is not changed at this time.
[0029]
If the electronic musical instrument is set in the edit mode, “Yes” is determined in step S12, and the process of step S22 is executed. In this step S22, arpeggio data (header indicating the correspondence between the sound pattern data and the arpeggio tone) and switching control according to the operation of the panel operator group 12 by the performer according to the display content of the display unit 13 Data is controlled to change. If the player does not perform such editing work, pre-stored arpeggio data and switching control data are maintained.
[0030]
On the other hand, the arpeggio tone generation control program of FIG. 3 is repeatedly executed every predetermined short time (for example, 1/480 of the time corresponding to the above-mentioned quarter note length, that is, one clock cycle). The execution of the arpeggio sound generation control program is started in step S30. If the arpeggio operation state flag RUN is set to “0”, it is determined as “No” in step S32, and in step S66. The execution of the arpeggio sound generation control program is once terminated. As described above, when the start of automatic accompaniment and automatic arpeggio is instructed and the operation state flag RUN is set to “1”, “Yes” is determined in step S32, and the processing from step S34 is performed. Execute.
[0031]
In step S34, when a performance operator related to a chord performance in the performance operator group 11 is operated, performance data representing the performance operator being operated (for example, a key number representing a key being depressed) is input. To do. When the same kind of performance data as described above is obtained from the external device 41 via the communication interface circuit 36, the performance data from the external device 41 is input. These performance data are stored in a performance data storage area provided in the RAM 34, and are erased from the performance data recording area when input is stopped. That is, the performance data relating to the performance operator being operated (for example, the key being pressed) is stored in the performance data storage area. However, in this performance data storage, performance data input within a short predetermined time is considered that the performance operator is operated at the same time, and performance data whose input has been stopped (for example, The performance data relating to the key that has been keyed off) is also stored for a predetermined short period of time for the processing of step S58 described later.
[0032]
Next, when new performance data is stored from the state in which no performance data is stored in the performance data storage area in the RAM 34 by the processing of steps S36 to S40, that is, all performance operators are operated. When a new performance manipulator is operated for the first time from a state where there is not, the timing count value TCNT which is controlled by the timer 32 and counted up at a rate corresponding to the performance tempo is reset to “0”. This timing count value TCNT counts up by “1” at every clock timing (1 / 480th of the 4th note), and starts counting up from “0” by the reset. Further, the type switching flag TCF indicating the switching of the sound generation pattern is set to “0” by “1”.
[0033]
First, the performance operator is continuously operated for arpeggio performance, or performance data indicating that performance is being performed is continuously input from the external device 41, and the arpeggio is based on the performance data stored in the performance data storage area. An operation of automatically playing a sound will be described. In this case, both “No” is determined in steps S42 and S44, and the type switching flag TCF is set to “0” by the processing in step S40 described above, so the determination of “No” in step S48. Then, the process of step S56 is executed.
[0034]
In step S56, the sound generation pattern data designated by the timbre selection data and the pattern selection data is referred to, and it is checked whether sound generation event data having timing data matching the timing count value TCNT exists. If there is no corresponding sounding event data, the process of step S56 is terminated, and the execution of the arpeggio sound sounding control program is terminated in step S66. If there is corresponding sound event data, performance data (data representing the pitch) that matches the key data in the sound event data is extracted from the performance data in the performance data storage area, The octave portion is processed using the octave data in the pronunciation event data.
[0035]
The performance data extraction and processing will be specifically described. For example, when performance data relating to the pitches C3, E3, and G3 is stored in the performance data storage area, the key data “1”, “2”, “3” are generated according to the pronunciation pattern data shown in FIG. The performance data representing the pitches C3, E3, and G3 are extracted. These pieces of performance data are maintained as they are by the octave data “+0”, and are increased by one octave by the octave data “+1”. The processed performance data is shown as a pitch in FIG. FIGS. 6A and 6B show examples of different tone generation pattern data with the performance data being the same as the above example.
[0036]
The CPU 31 adds the volume control velocity data and the key-on data for instructing the start of generation of the musical sound to the performance data processed as described above, and outputs the result to the musical sound signal generating circuit 14. In step S56, the performance data supplied to the musical tone signal generation circuit 14 as described above is processed using the timing count value TCNT and the gate time data in the sound generation event data related to the performance data. Thus, the sounding stop timing of the arpeggio sound controlled by the performance data is detected, and sounding stop instruction data (ie, key-off data) for instructing the sounding stop of the arpeggio sound is also output.
[0037]
The musical tone signal generation circuit 14 generates an arpeggio sound signal based on the supplied performance data and the aforementioned musical tone control data (tone color selection data representing the tone color of the arpeggio sound). Therefore, the generated arpeggio sound signal has a pitch and a volume specified by the performance data, and a tone color specified by the arpeggio tone color control data. The arpeggio sound signal is emitted through the sound system 18. The generation and sound emission of the arpeggio sound signal are terminated by the sound generation stop instruction data described above. As a result, the electronic musical instrument automatically follows the performance data from the performance operator group 11 and / or the external device 41, and automatically generates the arpeggio sound according to the sound pattern specified by the selected tone color and pattern selection data of the arpeggio sound. I play.
[0038]
Next, a case where the performer operates the pattern selection operator in the panel operator group 12 to switch the sound pattern of the arpeggio sound during the performance of such an arpeggio sound will be described. In this case, “Yes” is determined in step S44, and the type switching flag TCF is set to “1” in step S46. And CPU31 performs the process of step S50-S54 based on determination of "Yes" in step S48. In step S50, the switching control data shown in FIG. 7 is referred to, and switching timing data corresponding to the timbre represented by the timbre selection data is extracted. Then, the extracted switching timing data is compared with the timing count value TCNT to determine the switching timing.
[0039]
In this case, if the switching timing data does not indicate “anytime” but indicates a sound generation pattern switching (or end) timing, it is determined whether or not the timing count value TCNT matches the switching timing data. If not, it is determined as “No” in step S50, and the process of step S56 described above is executed. Therefore, in this state, an arpeggio sound according to the pronunciation pattern before switching is continuously generated.
[0040]
On the other hand, when the timing count value TCNT is counted up with the passage of time and coincides with the switching timing data, the pattern selection data is switched to data representing the sound generation pattern selected by the performer by the processing of steps S50 to S54. Further, the type switching flag TCF is changed to “0”, and the timing count value starts counting up from “0”. Since the process of step S56 described above is executed using the switched pattern selection data, the arpeggio sound generation pattern is switched to the switched sound generation pattern at this time. FIG. 8 shows a case where the selected sound pattern is switched to the type 2 sound pattern during the generation of the arpeggio sound based on the type 1 sound pattern under the condition that the switch timing data indicates a change for each measure. Two examples of the sound generation pattern switching timing are shown.
[0041]
Further, if the switching timing data represents “as needed”, when the performer switches the selection of the sound generation pattern, “Yes” is determined in step S50, and the processing from step S52 is executed. Thereby, in this case, when the performer switches the selection of the sound pattern, the sound pattern of the arpeggio sound is immediately switched to the new sound pattern that is switched.
[0042]
Next, operation of the performance operator group 11 for arpeggio performance is interrupted, input of performance data indicating that performance is being performed from the external device 41 is interrupted, or automatic arpeggio or automatic accompaniment is performed by operation of the panel operator group 12. A case where the operation stop is instructed will be described. Hereinafter, these states are referred to as arpeggio sound generation end instructions. In this case, it determines with "Yes" in step S42, and performs the process after step S58. In step S58, the performance data related to the performance operator that was being played until immediately before and / or the performance data that was input immediately before from the external device 41, that is, the performance data stored in the performance data recording area, is temporarily temporarily stored. Remember.
[0043]
After the process of step S58, in step S60, the switching control data shown in FIG. 7 is referred to, and based on the timing count value TCNT, the tone generation pattern selected before the instruction to end the arpeggio sound is ended. The same). The determination of the end timing is substantially the same as the determination process in step S50 described above. If the end timing has not been reached, the process of step S56 using the performance data temporarily stored in step S58 is executed. Thereby, the arpeggio sound by the pronunciation pattern selected before the end instruction of the arpeggio sound is continuously generated until the end timing is reached.
[0044]
On the other hand, when the end timing of the arpeggio sound is reached, in step S62, a signal instructing the end of generation of the arpeggio sound that has been continuously generated is output to the musical tone signal generation circuit 14. In step S64, the performance data stored temporarily is cleared. As a result, the arpeggio performance ends at the end timing.
[0045]
As can be understood from the above description of operation, according to the above embodiment, even if the sound generation pattern is switched by the performer during the generation of the arpeggio sound by the processing of steps S44 to S54 in FIG. Until the switching timing designated by the stored switching timing data, an arpeggio sound based on the sounding pattern data before the switching is generated, and thereafter an arpeggio sound based on the sounding pattern data after the switching is generated. In addition, even if the end of the arpeggio sound is instructed by the player during the generation of the arpeggio sound by the processing of steps S42 and S58 to S64 in FIG. 3, the end timing specified by the switching timing data stored corresponding to the tone. Until, the arpeggio sound based on the pronunciation pattern data before the end instruction is generated, and then the generation of the arpeggio sound is ended.
[0046]
As a result, according to the above-described embodiment, it is possible to eliminate the unnaturalness of the arpeggio sound due to the change or stop of the sound generation pattern, regardless of the sound pattern switching instruction and the generation end instruction. Sound can be generated. In addition, since the timing data that specifies the timing to switch the pronunciation pattern and the end timing of the arpeggio sound is associated with each tone, it is possible to perform an arpeggio performance that is suitable for the tone of the arpeggio tone and within the same tone Since the switching timing is unified in the switching of the sound pattern in, a stable arpeggio performance can be enjoyed.
[0047]
Further, in the above embodiment, the performer can correct (add, change, delete, etc.) the arpeggio data (sounding pattern data and header) and the switching control data by the processing in steps S12 and S22 in FIG. Thereby, while a user's will is reflected in an arpeggio performance, the arpeggio performance according to a user preference is realizable.
[0048]
Furthermore, in carrying out the present invention, the present invention is not limited to the above embodiment and its modifications, and various modifications can be made without departing from the object of the present invention.
[0049]
For example, in the above embodiment, data specifying the end of every predetermined number of bars or beats is stored as the switching timing data. However, instead of this, data specifying the end of a predetermined section from the start of the pronunciation pattern, for example, data indicating the end of two measures from the start of the pronunciation pattern, the end of the pronunciation pattern, etc. may be used as the switching timing data.
[0050]
In the above-described embodiment, the timing count value TCNT is reset to “0” when the sound generation pattern is switched by the process of step S54. However, this reset is omitted and newly selected sound generation pattern data is stored. The search may be performed according to the timing count value TCNT that is continuously counted up.
[0051]
In the above embodiment, when the operation of the performance operator group 11 is interrupted and / or when the performance data input from the external device 41 is interrupted, the performance data stored in the performance data storage area is stored. I cleared it. However, instead of this, when the operation of the performance operator group 11 is interrupted last and / or when the input of performance data from the external device 41 is interrupted last, a new operation of the performance operator group 11 and The performance data before the interruption may be stored and saved in the performance data storage area until new performance data is input from the external device 41. In this case, the storage and saving process is performed in step S34 in FIG. 3, and it is not determined in the determination process in step S42 that the operation of the performance operator group 11 is interrupted and / or the performance data input from the external device 41 is not interrupted. You can do it. Thereby, even if the performance of the performance operator group 11 and / or the external device 41 is interrupted, the arpeggio performance having a so-called memory function can be performed in which the arpeggio performance is continued.

In the above embodiment, an example in which one sounding pattern data is always assigned to one tone color has been described. However, instead of this, one sounding pattern data may be assigned to a plurality of different timbres. For example, the pronunciation pattern data 2 is assigned to both timbre A and timbre B. The switching timing data regarding the timbre A indicates the end of every measure, and the switching timing data regarding the timbre B is “as needed”. In this case, when the sound pattern A 2 is switched to another sound pattern data while the timbre A is selected, the arpeggio performance based on the sound pattern data 2 is switched to the arpeggio performance based on the other sound pattern data at the end of the measure. When the sound pattern B is switched to another sound pattern data while the timbre B is selected, the arpeggio performance based on the sound pattern data 2 is immediately switched to the arpeggio performance based on the other sound pattern data.

Furthermore, in the above embodiment, an electronic musical instrument that employs a key as a performance operator has been described. However, instead of a key, a simple press switch, touch switch, or the like may be employed as a performance operator that designates a pitch. The present invention can also be applied to other devices such as a sequencer device and a personal computer as long as the device can input performance data by connecting a keyboard device and other external devices.
