When the user operates the input operation element 11, information representing the operation content is supplied to a computer section 12 described later via the bus 19. Instead of a part or all of the controls constituted by hardware, an image simulating the controls is displayed on the display 13 and the operation of the controls is performed according to the operation of the touch panel TP. Information indicating the content may be supplied to the computer unit 12.

  The computer unit 12 includes a CPU 12a, a ROM 12b, a RAM 12c, and a timer 12d connected to a bus 19, respectively. The CPU 12a reads various programs from the ROM 12b and executes various processes. For example, the CPU 12a controls a sound source circuit 16, which will be described later, to generate a digital tone signal. Further, for example, the CPU 12a controls the effect circuit 17 to give an effect to the musical tone represented by the digital musical tone signal.

  The CPU 12 a generates display data representing display contents using graphic data, character data, and the like, and supplies the display data to the display 13.

The ROM 12b stores, in addition to the various programs, initial values of various parameters, graphic data for generating display data representing an image displayed on the display 13, character data, and the like. For example, the ROM 12b stores a plurality of tone control pattern data sets SPS _{n = 1, 2} ,. Tone control pattern data sets SPS _n, as shown in FIG. 3, consisting of the musical tone control pattern data SP x _{= 1 to 4} of a plurality (e.g., four) respectively representing the variation pattern when the parameters defining the mode of musical tones. As will be described in detail later, the electronic musical instrument 10 has an operation mode for selecting a control pattern in a musical tone mode according to the strength of pressing a key of the keyboard device KY. Each tone control pattern data SP _x corresponds to a range of key depression strength. Specifically, as shown in FIG. 4, when the key depression strength is equal to or more than “1” and less than “32”, the tone control pattern data SP _{x = 1} is selected. When the key depression strength is equal to or more than “32” and less than “64”, the tone control pattern data SP _{x = 2} is selected. When the key depression strength is equal to or more than “64” and less than “96”, the tone control pattern data SP _{x = 3} is selected. When the key depression strength is equal to or more than “96” and less than “128”, the tone control pattern data SP _{x = 4} is selected. Note that the minimum value of the key pressing strength is “1”, and the maximum value of the key pressing strength is “127”.

Musical tone control pattern data SP _x, as shown in FIG. 5, the parameter identification data SI indicates the parameter type, a plurality of musical tone control data _{SC m = 1, 2,} consists of _.... The parameter identification data SI is data (for example, a parameter name) for identifying a parameter that can be controlled by the tone generator 16 or the effect circuit 17. In the example of FIG. 3, the parameter identification data SI represents the cutoff frequency of the filter circuit of the sound source circuit 16. Each musical tone control data SC _m consists set value SV of the timing data ST and parameters representative of the change time of the value of the parameter. The timing data ST in FIG. 5 represents a measure: beat: clock number. The number of clocks for one beat is set to “480”. The length of the musical tone control pattern data SP _x shown in FIG. 5 is a four bars. In the present embodiment, the parameter identification data SI of the musical tone control pattern data SP _{x = 1 to 4} is common.

  Various data are temporarily stored in the RAM 12c when various programs are executed. The timer 12d includes a clock generator that outputs a clock signal (pulse). This clock signal is used, for example, as a reference signal when reproducing the time-varying pattern of the parameter value at the set tempo.

  The display 13 is configured by a liquid crystal display (LCD) or the like. The display 13 displays an image based on the display data supplied from the CPU 12a. For example, the name of the currently selected musical tone, the values of various parameters defining the mode of the musical tone, and the like are displayed. As described above, the display 13 may include the touch panel TP.

The storage device 14 includes a large-capacity nonvolatile recording medium such as an HDD and a DVD, and a drive unit corresponding to each recording medium. Further, the storage device 14 may be composed of a large-capacity flash memory. The above-mentioned tone control pattern data SP _x and other parameter values may be stored in the storage device 14.

  The external interface circuit 15 includes a connection terminal that enables the electronic musical instrument 10 to be connected to an external device such as another electronic musical instrument or a personal computer by a wire, a circuit that enables a wireless connection, and the like. The electronic musical instrument 10 can be connected to a communication network such as a LAN (Local Area Network) and the Internet via the external interface circuit 15.

  The tone generator 16 is connected to a waveform memory WM. The waveform memory WM stores a plurality of musical tone waveform data each representing an acoustic waveform of a musical tone such as a piano, an organ, a violin, and a trumpet. The tone generator 16 reads the tone waveform data specified by the CPU 12a from the waveform memory WM. The read musical tone waveform data is corrected in accordance with the value of the parameter supplied from the CPU 12a to generate a digital musical tone signal, which is supplied to the effect circuit 17. Note that the method of the sound source circuit 16 is not limited to the waveform memory method, and various methods such as an FM (frequency modulation) method, a physical model method, and an analog simulation method can be adopted. In addition, the digital tone signal is not limited to that constituted by dedicated hardware, but may be generated by software processing using a CPU, a DSP, or the like. In addition, a digital sound signal such as a sound or a sound effect may be generated without being limited to a musical sound.

  The effect circuit 17 adds effects such as reverb and chorus to the tone represented by the digital tone signal in accordance with the value of the parameter supplied from the CPU 12a, and supplies the tone to the sound system 18.

  The sound system 18 includes a D / A converter that converts a digital tone signal supplied from the effect circuit 17 into an analog tone signal, and an output terminal that outputs the analog tone signal. Note that the electronic musical instrument 10 does not need to include the sound system 18. In this case, the electronic musical instrument 10 preferably outputs a digital musical tone signal to an external device, and the digital musical tone signal is converted into an analog musical tone signal by a sound system provided in the external device.

Next, the operation of the electronic musical instrument 10 will be described. In particular, the tone control function will be described. When the user operates the cursor key CK, the touch panel TP, and the like to activate the tone control function, the CPU 12a executes a tone control program (not shown). Thus, the CPU 12a functions as a device including the trigger signal switching unit TS and the musical tone control pattern data reproducing unit PL, as shown in FIG. Next, the user, the cursor keys CK, by using a touch panel TP, thereby selecting a tone color and tone control pattern data sets SPS _n, to set the playback tempo of the musical tone control pattern data sets SPS _n. Incidentally, even during play, can be changed tone color, the tone control pattern data sets SPS _n and tempo. Next, the user, the cursor keys CK, by operating the touch panel TP, selects an operation mode relating to the reproduction and stop of the musical tone control pattern data SP _x (first operation mode or the second operation mode).

  In any of the operation modes, when a key of the keyboard device KY is pressed, the keyboard device KY supplies the tone generator circuit 16 with key-on information indicating the pitch and strength of the pressed key. When the pressed key is released, the keyboard device KY supplies the tone generator 16 with key-off information indicating the pitch of the released key. Further, the external interface circuit 15 supplies the key-on information and the key-off information supplied from the external device to the sound source circuit 16. The tone generator 16 starts generating a digital tone signal according to the key-on information. Further, the tone generator 16 stops generating a digital tone signal according to the key-off information. The key-on information and the key-off information correspond to the pronunciation information of the present invention.

  The trigger signal switching unit TS switches the trigger signal to be supplied to the tone control pattern data reproduction unit PL according to the operation mode, as described below. The trigger signal switching unit TS is supplied with an output signal of the start / stop switch SS, an output signal of the keyboard device KY, and key-on information and key-off information supplied from an external device. In the first operation mode, the trigger signal switching unit TS supplies the output signal of the start / stop switch SS to the musical tone control pattern data reproduction unit PL as a trigger signal. On the other hand, in the second operation mode, the trigger signal switching unit TS supplies, as a trigger signal, the output signal of the keyboard device KY and the key-on information and key-off information supplied from the external device to the musical tone control pattern data reproducing unit PL.

In the first operation mode, the musical tone control pattern data reproducing unit PL performs predetermined data (for example, musical tone control pattern data SP _{x = 1)} of the musical tone control pattern data SP _x of the selected musical tone control pattern data set SPS _n. ) Is played repeatedly. That is, in the first operation mode, when the start / stop switch SS is switched from the off state to the on state, the tone control pattern data reproducing unit PL reads the tone control pattern data SP _{x = 1} from the ROM 12b, the storage device 14, and the like. read out. Then, the tone control pattern data reproducing section PL calculates the timing for changing the value of the parameter based on the set tempo and the timing data ST. Then, at each of the calculated timings, the parameter identification data SI and the parameter set value SV corresponding to the calculated timing are supplied to the tone generator 16. When the musical tone control pattern data SP _x is supplied while the tone generator circuit 16 is generating a tone signal, aspects of the tone represented by said musical tone signal is varied in accordance with musical tone control pattern data SP _x.

In the first operation mode, when the start / stop switch SS is switched from the on state to the off state, the musical tone control pattern data reproducing unit PL stops reproducing the musical tone control pattern data SP _{x = 1} .

In the second operation mode, the musical tone control pattern data reproducing unit PL when the key-on information is supplied as a trigger signal, in accordance with the key depression intensity included in the key-on information, musical tone control of the musical tone control pattern data sets SPS _n play pattern data _{SP x =} 1 _~SP x = 1 single tone control pattern data SP _x of the _four. That is, when the key depression strength is equal to or more than “1” and less than “32”, the tone control pattern data reproducing unit PL reproduces the tone control pattern data SP _{x = 1} . When the key depression strength is equal to or more than “32” and less than “64”, the tone control pattern data reproducing unit PL reproduces the tone control pattern data SP _{x = 2} . When the key depression strength is equal to or greater than “64” and less than “96”, the tone control pattern data reproducing unit PL reproduces the tone control pattern data SP _{x = 3} . When the key depression strength is equal to or more than “96” and less than “128”, the tone control pattern data reproducing unit PL reproduces the tone control pattern data SP _{x = 4} . Note that the range of the key pressing strength may be fixed, or may be configured to be changeable by the user. Also, for each musical tone control pattern data SP _x, it may be different range of key depression strength. Further, the musical tone control pattern data SP _x to be reproduced in all the key depression intensity range may be present.

  In the second operation mode, the tone control pattern data reproducing unit PL has a plurality of (three types in this embodiment) retrigger modes. The user operates the cursor key CK, the touch panel TP, and the like to select one of the first retrigger mode, the second retrigger mode, and the third retrigger mode in advance.

  When the first retrigger mode is selected and new key-on information is supplied during reproduction of the musical tone control pattern data, the musical tone control pattern data reproducing section PL sets the reproduction position of the musical tone control pattern data to the beginning. And the reproduction of the tone control pattern data is continued. When all the keys are released (when all the keys are in the non-operating state), the musical tone control pattern data reproducing unit PL stops reproducing the musical tone control pattern data.

  When new key-on information is supplied during reproduction of the tone control pattern data when the second retrigger mode is selected, the tone control pattern data reproducing unit PL outputs the tone control pattern data being reproduced. Continue playing. After playing back to the end of the tone control pattern data being played back, the tone control pattern data playback unit PL returns to the beginning of the tone control pattern data and continues playing. When all the keys are released (when all the keys are in the non-operating state), the musical tone control pattern data reproducing unit PL stops reproducing the musical tone control pattern data. Thereafter, when new key-on information is supplied, the tone control pattern data reproducing unit PL starts reproduction from the beginning of the tone control pattern data corresponding to the new key-on information.

  When the third retrigger mode is selected, the musical tone control pattern data reproducing section PL starts reproduction from the beginning of musical tone control pattern data corresponding to the key-on information, using the first key-on information as a trigger, and thereafter, reproduces the musical tone. The control pattern data is repeatedly reproduced. That is, even when all keys are released (or a state equivalent to a state where all keys are released), the reproduction of the tone control pattern data is continued.

As described above, in the first operation mode, is reproduced musical tone control pattern data SP _x from the middle generation of tone signal, it is possible to vary the manner of the musical tone. In the first operation mode, in the course generates musical tone signals, to stop the reproduction of the musical tone control pattern data SP _x, it is possible to stop the fluctuations of the aspects of the musical tone. In the second mode of operation, it can be synchronized to the key-on information to start the reproduction of the musical tone control pattern data SP _x. That is, only by supplying the key-on information, the generation of the musical tone signal is started, and the form of the musical tone represented by the musical tone signal starts to fluctuate according to the musical tone control pattern data. Further, the user can select one of the first to third retrigger modes in the second operation mode. As described above, the electronic musical instrument 10 includes a plurality of units for controlling the reproduction and stop of the musical tone control pattern data, and the user can select an optimal unit according to the application. It should be noted that only one or two of the three types of retrigger modes described above may be provided. Further, another retrigger mode may be provided.

In the second operation mode, among the musical tone control pattern data SP x _{= 1} to the musical tone control pattern data SP x _{= 4,} the musical tone control pattern data SP _x corresponding to the key depression intensity is selected. Thus, the performance mode of the user is reflected in the control pattern of the mode of the musical sound.

  Therefore, according to the electronic musical instrument 10, a richer performance expression can be realized than the conventional electronic musical instrument.

(2nd Embodiment)
Next, an electronic musical instrument 20 according to a second embodiment of the present invention will be described. The configuration of the electronic musical instrument 20 is almost the same as the configuration of the electronic musical instrument 10. However, as shown in FIG. 7, the musical tone control pattern data sets SPS _n consists of one musical tone control pattern data SP.

  The operation of the electronic musical instrument 20 in the first operation mode is the same as the operation of the electronic musical instrument 10 in the first operation mode.

In the second operation mode, the musical tone control pattern data reproducing unit PL when the key-on information is supplied, the key-on in accordance with the key depression intensity included in the information, the musical tone control pattern data SP of the tone control pattern data sets SPS _n And reproduces the corrected tone control pattern data. For example, when the key depression strength is equal to or more than “1” and less than “32”, the tone control pattern data reproducing unit PL multiplies each set value SV of the tone control pattern data SP by “0.25” as a coefficient. The reproduced tone control pattern data is reproduced. When the key depression strength is “32” or more and less than “64”, the tone control pattern data reproducing unit PL is obtained by multiplying each set value SV of the tone control pattern data SP by “0.5” as a coefficient. Play the tone control pattern data. When the key depression strength is equal to or greater than "64" and less than "96", the musical tone control pattern data reproducing unit PL reproduces the musical tone control pattern data SP as it is. When the key depression strength is not less than “95” and not more than “127”, the tone control pattern data reproducing unit PL is obtained by multiplying each set value SV of the tone control pattern data SP by “1.25” as a coefficient. Play the tone control pattern data. The operation related to the retrigger is the same as in the first embodiment. Further, the configuration related to the range of the key pressing strength may be modified in the same manner as the modification of the first embodiment.

  As described above, in the second operation mode of the second embodiment, the tone control pattern data SP is modified according to the key depression strength. Thus, the performance mode of the user is reflected in the control pattern of the mode of the musical sound. Therefore, according to the electronic musical instrument 20, a richer performance expression can be realized than the conventional electronic musical instrument.

  Furthermore, the implementation of the present invention is not limited to the above embodiment, and various changes can be made without departing from the purpose of the present invention.

For example, in the first embodiment, the parameter identification data SI of the tone control pattern data SP _{x = 1 to 4} is common, but the parameter identification data SI of each tone control pattern data SP _x may be different.

Further, in the first embodiment, the musical tone control pattern data SP _{x = 1 to 4} are respectively assigned to the ranges of the key pressing strength, but are set so that the ranges of the key pressing strengths do not overlap with each other. ing. However, the present invention is not limited to this, and the ranges of the key pressing strength may overlap. For example, it may be set so that the tone control pattern data SP _{x = 1} and the tone control pattern data SP _{x = 2} are selected when the key depression strength is equal to or more than “1” and less than “64”. In this case, it is preferable that the parameter identification data SI of the tone control pattern data SP _{x = 1 and} the parameter identification data SI of the tone control pattern data SP _{x = 2 be} different. According to this, the values of the two parameters can be changed simultaneously.

Further, in a tone control pattern data SP _x, it may be assigned a range of a plurality of key depression strength. That is, for example, when the key pressing strength is “1” or more and less than “32”, or when the key pressing strength is “96” or more and “127” or less, the tone control pattern data SP _{x = 1} is selected. May be set as follows.

  When new key-on information is supplied during reproduction of the tone control pattern data when the first retrigger mode is selected, the tone control pattern data reproduction unit PL stops reproducing the tone control pattern data. Then, the reproduction may be started from the beginning of the tone control pattern data corresponding to the new key-on information.

In the first embodiment, the musical tone control pattern data SP _x corresponding to the key depression intensity is selected. Alternatively, the musical tone control pattern data SP _x corresponding to range that contains the pitch of the key-on information may be selected. For example, it is assumed that the musical tone control pattern data set SPS _n is composed of two musical tone control pattern data SP _{x = 1} and musical tone control pattern data SP _{x = 2} . In this example, when the pitch of the key-on information is “C3” or more and less than “A5”, the tone control pattern data SP _{x = 1} is selected, and the pitch of the key-on information is less than “C3” or “A5” or more. At some point, the tone control pattern data SP _{x = 2} may be selected. The range of the pitch may be fixed, or may be configured to be changeable by the user. Further, according to the combination of the key depression strength and tone pitch, tone control pattern data SP _x may be selected.

In the second embodiment, the tone control pattern data SP is modified according to the keystroke strength. Instead, the tone control pattern data SP may be modified according to the range in which the pitch of the key-on information is included. For example, when the pitch of the key-on information is equal to or more than “C3” and less than “A5”, the musical tone control pattern data reproducing unit PL reproduces the musical tone control pattern data SP as it is. When the pitch of the key-in information is less than “C3” or more than “A5”, the tone control pattern data reproducing unit PL multiplies each set value SV of the tone control pattern data SP by “1.25” as a coefficient. The obtained tone control pattern data is reproduced. In this case, also in this case, the range of the pitch may be fixed or may be configured to be changeable by the user. Further, the coefficient may be set according to the combination of the key pressing strength and the pitch. May be selected. Also, depending on either one or both of the key depression strength and pitch, as well as select a musical tone control pattern data SP _x, it may be modified musical tone control pattern data SP.

  Further, for example, in the second embodiment, the reproduction tempo, the reproduction direction, and the like of the musical tone control pattern data may be changed according to the range in which the key depression strength or the pitch of the key-on information is included.

Further, the musical tone control pattern data reproducing unit PL may interpolation calculation tone control data in one or more of timing between the tone control data SC _m and tone control data SC m _{+ 1.} In this case, towards the musical tone control data SC m _{+ 1} of the set value SV from the set value SV of the musical tone control data SC _m, it is possible arbitrarily set the change curve of the set value. For example, from the set value SV of the musical tone control data SC _m to the tone control data SC m _{+ 1} of the set value SV, set value may be set to change linearly. Further, the type of the change curve may be selected according to a key pressing strength or a range including a pressed key.

Alternatively, you associate the musical tone control pattern data sets SPS _n and tone, when the tone color is selected, the musical tone control pattern data sets SPS _n associated with the tone may be selected (enabled).

  In the above embodiment, an example has been described in which the present invention is applied to the electronic musical instrument 10 having performance operators. However, the present invention is also applicable to a tone generator module having no performance operators. The present invention is also applicable to an electroacoustic apparatus realized by executing a performance program on a general-purpose personal computer or tablet computer. In these cases, performance information (sound generation information) may be input from an external device via the external interface circuit 15.

Also, the example shown in FIG. 5 shows an example of musical tone control data SC _m is stored in one every eighth note (total of 32), this is merely an example, more coarse timing, or fine timing, for example, musical tone control data SC _m every quarter note and 16-note or the like may be stored. Further, not limited to four measures the length of the musical tone control data SC _m. Also, the set value in the musical tone control pattern may not be used as it is as a parameter, but may be used as a parameter after processing the set value.
