Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical tone generating device for generating a musical tone having reverberation in an electronic musical instrument or the like.

[0002]

2. Description of the Related Art A musical tone generator used in electronic musical instruments such as electronic organs, electronic pianos, single keyboards and synthesizers has a plurality of digital control oscillators (hereinafter referred to as "DCO") as sound sources. By producing a sound by combining these DCOs, for example, a musical tone signal corresponding to a tone color designated by an operation panel or a tone range designated by a keyboard is generated (see, for example, Japanese Patent Laid-Open No. 2-66597). ).

For example, an electronic piano is provided with three oscillators DCO1 to DCO3 for generating three kinds of tone component signals in order to generate a tone corresponding to one key. Then, when one key is pressed, each of the oscillators DCO1 to DCO3 generates a musical tone component signal, and these are combined into one to become a final musical tone signal for one key.

The tone component signals generated by each of the above-mentioned oscillators are a weak striking component signal (for example, DCO1), a strong striking component signal (for example, DCO2), and a striking component signal (for example, DCO3).

Here, the weak tap component is a musical tone component of one musical tone whose frequency changes substantially in proportion to the pitch and has a relatively long sounding time. The strong stroke component is a musical tone component of one musical tone whose frequency changes substantially in proportion to the pitch and has a relatively short sounding time. The striking component is a component of one musical sound, which is not necessarily proportional to the pitch frequency and has a shorter sounding time. This striking component is, for example, a noise component in a piano attack.

As described above, the oscillator prepared for each musical tone component generates the musical tone signal of each musical tone component, and synthesizes these to generate one musical tone. Has occurred.

An electronic piano is usually provided with as many tone signal generation circuits as one set of three oscillators, as many as the polyphonic number (the number of simultaneous sounds).

By the way, an actual acoustic piano is not provided with a damper in the high tone range. Therefore, when a high-pitched tone is tapped, a resonance sound of strings and frames is generated and reverberation occurs.

Therefore, it has been attempted to simulate a state in which such reverberation occurs in an electronic piano and generate a musical sound closer to that of an acoustic piano. For example,
A reverberation adding device that adds reverberation only to a musical sound in a specific high range has been considered.

However, the circuit of such a reverberation adding device is complicated and large-scaled, and there is a problem that the cost of the musical tone generating device and eventually the electronic musical instrument becomes high.

[0011]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and produces a musical tone capable of producing reverberation close to that of a natural musical instrument with a simple and inexpensive structure without using a reverberation adding device. The purpose is to provide a device.

[0012]

A tone generating apparatus of the present invention reads out waveform data of a plurality of tone components stored in advance, reproduces tone component signals, and synthesizes these to generate a tone signal. In the musical tone generating device, for at least one specific musical tone component among the plurality of musical tone components, a storage means in which waveform data having no reverberation and waveform data having reverberation are stored, and a pitch to be pronounced are indicated. Instructing means and waveform data having no reverberation of a specific musical tone component is read from the storage means when a pitch in a predetermined tone range is instructed by the instructing means, and the storage is performed when a pitch in another tone range is instructed. A musical tone component signal generating means for reading waveform data having reverberation of the specific musical tone component from the means to generate a musical tone component signal of the specific musical tone component; and a specification generated by the musical tone component signal generating means. It is characterized by comprising a tone component signal of a tone component and a tone signal generating means for generating a tone signal by synthesizing a tone component signal generated according to waveform data of a tone component other than the specific tone component. .

[0013]

According to the present invention, for waveform data of a specific musical tone component, waveform data having reverberation and waveform data having no reverberation are prepared in advance in the storage means, and the tone range to be reverberated is designated by the instructing means. At this time, the waveform data of the specific musical sound component having the reverberation is read out and sounded.

Accordingly, even if a reverberation adding device is not provided,
Since the waveform data having reverberation is stored in advance and is read out according to the musical range, it is possible to generate a musical tone with reverberation, so that a musical tone closer to a natural musical instrument can be generated. It is possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an outline of a musical sound generating apparatus according to the present invention will be described with reference to FIG.

In the figure, DCO1 is a weak component, DCO
Reference numeral 2 is a digital control oscillator for generating a musical tone component signal of a striking component and DCO 3 is a striking component. These three DCO1～3, constitute the musical tone signal generating circuit 50 ₁ to 50 _l for generating one tone. And
The musical tone component signals generated by the DCOs 1 to 3 are added to form one musical tone signal, which is emitted through the sound system.

In the electronic musical instrument, the musical tone signal generating circuits are prepared for the number of simultaneous sound generations defined in the specifications of the electronic musical instrument, that is, the polyphonic number n. This allows
For example, a plurality of tones such as chords can be simultaneously pronounced.

In the following description, the case where the polyphonic number is "32" will be described.

Here, as described above, the weak tap component generated by the DCO 1 is a musical tone component of which the frequency is changed substantially in proportion to the pitch of one musical tone and the tone generation time is relatively long. The strong hit component generated by the DCO 2 is a musical tone component of one musical tone, the frequency of which changes substantially in proportion to the pitch, and the tone generation time is relatively short.

The striking component generated by the DCO 3 is a component of one musical tone, which is not necessarily proportional to the pitch frequency and has a shorter sounding time. This striking component is, for example, a noise component in a piano attack.

FIG. 2 shows the relationship between the pitch and frequency of each tone component. FIG. 2 shows that the frequency of the striking component DCO3 is not necessarily proportional to the pitch.

FIG. 3 is a block diagram showing the construction of the essential parts of an electronic musical instrument to which the musical tone generating apparatus according to the present invention is applied.

In the figure, the keyboard unit 1 is composed of a keyboard having a plurality of keys, and includes a key scan circuit for detecting the pressed state of each key. The touch sensor 1a detects the strength (speed) of key touch according to a signal from the keyboard unit 1. The data indicating the pressed state of each key and the touch data indicating the strength of the key touch are sent to the CPU 3.

The panel section 2 is provided with various switches such as a mode designation switch, a melody selection switch, and a rhythm selection switch.

The central processing unit (CPU) 3 controls each section of the electronic musical instrument in accordance with a control program stored in a program memory section 41 of a read only memory (hereinafter referred to as "ROM") 4.

The ROM 4 is the program memory section 41.
In addition, it has a tone color data memory section 42. The tone color data memory section 42 stores frequency numbers, waveform numbers, envelope waveform numbers, mode data, etc., which are data for generating a tone signal. Each of these data is designated by the tone color pointer.

The tone color pointer is changed according to a panel operation or keyboard operation, and the respective data designated by the changed tone color pointer are read from the ROM 4. Then, it is supplied to the musical sound generating device by performing a predetermined calculation.

Random access memory (hereinafter "RAM")
Say. ) 5 corresponds to the state of each key and switch of the keyboard section 1, the touch sensor 1a and the panel section 2, a data area for transferring and storing necessary data stored in the ROM 4 under the control of the CPU 3. It includes a plurality of registers in which data necessary for sound emission is set, an assigner memory A, B, C, etc. for storing data for allocating a tone signal generating circuit described later to an unused channel.

The musical tone generating section 6 generates a musical tone signal. The musical tone generating section 6 is a weak tap component musical tone signal generating section 1 for generating a sound that is always produced from a weak tap to a strong tap.
1, for example, a strong component sound signal generation unit 12 that generates a strong sound that becomes a loud sound, a component sound signal generation unit 13 that generates a striking sound at the time of keystroke, and signals of these musical components are added. It is composed of an adder 15.

The above-mentioned weak tap component tone signal generation section 11, strong tap component tone signal generation section 12, and hit component musical tone signal generation section 13
Is 3 so that 32 sounds can be pronounced at the same time.
It has two identical circuits. Details of these will be described later.

The tone generator 6 is connected to a waveform memory 21 for storing waveform data and an envelope waveform memory 29 for storing envelope data.
The details of these will be described later.

The digital tone signal output by the tone generator 6 is supplied to the D / A converter 7. D / A converter 7
Converts an input digital musical tone signal into an analog musical tone signal, and the analog musical tone signal output from the D / A converter is supplied to the sound system 8.

The sound system 8 is composed of, for example, a speaker or a headphone, and is a well-known one which emits sound according to an inputted musical sound signal.

The touch sensor 1a (keyboard section 1), the panel section 2, the CPU 3, the ROM 4, the RAM described above are used.
The system 5 and the musical tone generator 6 are connected to each other.

FIG. 4 shows a detailed configuration of the tone signal generating circuit, which is the above-mentioned weak-tone component tone signal generating section 1
1. The high-strength component musical sound signal generation unit 12 and the striking component musical sound signal generation unit 13 are all configured by the same circuit, and generate musical tone component signals of weak striking, strong striking, and striking components, respectively, under the control of the CPU 3.

In the figure, the waveform upper address register 2
0 stores the upper waveform address sent from the CPU 3. This waveform upper address register 20
Is supplied to the waveform memory 21 and is used to select a waveform corresponding to the tone color or range stored in the waveform memory 21.

The waveform memory 21 is a ROM that stores waveform data, and the waveform upper address register 20 is used.
Waveform upper address and the mode selector 2 described later
The waveform data selected by the waveform lower address from 5 is output.

The storage state of the waveform data of each tone component in the waveform memory 21 is shown in the image of FIG. That is, with respect to the weak hit component DCO1 and the strong hit component DCO2, the waveform data to be read is changed every 6 keys from the lowest key. This is because the musical tone of a piano has a remarkably different waveform depending on the musical range, and it is necessary to use a waveform suitable for the musical range.

On the other hand, the striking component DCO3 has a waveform that is not so different depending on the tone range, and its frequency is not necessarily proportional to the pitch. Therefore, a common waveform is used in the tone range with a damper. Then, the waveform data of the striking component to which reverberation is added in advance in a high frequency without a damper is read.

FIG. 6 shows the waveform data stored in the waveform memory 2.
It is a figure which shows an example of the state memorize | stored in 1. The storage format is not limited to the illustrated example.

The reading of the waveform data from the waveform memory 21 is performed at a speed (frequency) corresponding to the frequency number generated corresponding to the key number.

The frequency number register 22 is the CPU 3
It stores the frequency number sent from. Here, the frequency number is used to control the speed of reading the waveform data from the waveform memory 21, and actually represents the increment of the read address of the waveform memory 21.

As a result, when the frequency number is small, the waveform data is read at a small pitch (address interval), so that a tone signal of a low frequency is generated, and when the frequency number is large, the waveform data is generated at a large pitch (address interval). Is read to generate a high-frequency tone signal. The output of the frequency number register 22 is supplied to one input of the adder 23.

The adder 23 uses the output of the frequency number register 22 as one input, and receives the address register 24.
Is used as the other input to perform addition, and the result is output again to the address register 24.

The address register 24 stores the output of the adder 23 described above, and the address register 24 and the adder 23 constitute an accumulator. The contents of the address register 24 are supplied to the waveform memory 21 via the mode selector 25 as the lower waveform address.

The mode selector 25 controls the method of reading from the waveform memory 21. For example, the area specified by the waveform upper address of the waveform memory 21 is sequentially read in the direction of increasing addresses, and when the end is reached, the operation is returned to the beginning and the above operation is repeated, or if the end of the area specified by the waveform upper address is read. Next, various reading methods such as whether to read in the address decreasing direction (reverse direction) are controlled according to a control signal (not shown) from the CPU 3. The output of the mode selector 25 is supplied to the waveform memory 21 as a waveform lower address.

The touch data conversion circuit 26 converts the touch data of a predetermined format sent from the CPU 3 into a format that can be handled by the tone signal generation circuit. Here, the touch data is data obtained by detecting the strength of key depression of the key with the touch sensor 1a. The output of the touch data conversion circuit 26 is supplied to the envelope generator 27.

The musical tone component selection register 28 is a register for storing data for selecting the types of musical tone components such as weakly striking components, strong striking components, striking components without reverberation, striking components with reverberation, etc. sent from the CPU 3. . The output of the tone component selection register 28 is the envelope waveform memory 2
9 is supplied.

The envelope waveform memory 29 stores various envelope data corresponding to musical tone components.
The predetermined envelope data is selected by using the contents of the tone component selection register 28 as an address.

The envelope generator 27 sequentially reads the envelope data selected by the tone component selection register 28 from the envelope waveform memory 29, and generates an envelope signal having a size (amplitude) according to the touch data from the touch data conversion circuit 26. And sends it to the multiplier 30.

The multiplier 30 adds an envelope to the waveform data by multiplying the waveform data read from the waveform memory 21 and the envelope signal supplied from the envelope generator 27 to generate a digital tone component signal. The output of the multiplier 30 is supplied to the adder 15 (see FIG. 3) as one tone component signal.

The waveform memory 21 and the envelope waveform memory 29 shown in FIG. 4 are memories commonly used in each tone signal generating circuit, and the other portions are hardware individually provided in each tone signal generating circuit. It is wear.

The plurality of tone signal generating circuits described above may be configured to be used in a time division manner. In this case,
There is an effect that the amount of hardware constituting the tone signal generation circuit can be reduced.

FIG. 7 shows the configuration of the above-mentioned weak tap component tone signal generation section 11, strong tap component tone signal generation section 12, hit component musical tone signal generation section 13 and its control system. In the figure, adders 15a, 15b and 15c correspond to the adder 15 shown in FIG.

The assign control section A3a is realized by the function of the CPU 3, and controls the _first to _32nd tone signal generating circuits 11 _{1 to} 11 ₃₂ . The assign control unit A3a is an assigner memory A provided in the RAM5.
Channel allocation processing is performed according to the contents of 5a.

The assign control unit B3b is also realized by the function of the CPU 3, and controls the 33rd to 64th tone signal generation circuits 12 _{1 to} 12 ₃₂ . The assign control unit B3b performs channel assignment processing according to the contents of the assigner memory B5b provided in the RAM5.

The assignment control section C3c is also realized by the function of the CPU 3, and controls the 65th to 96th tone signal generating circuits 13 _{1 to} 13 ₃₂ . The assign control unit C3c performs channel allocation processing according to the contents of the assigner memory C5c provided in the RAM5.

FIG. 8 shows an example of the assigner memory A. The assigner memory A is composed of a channel number 1, a key state ST, a key number NO and a key pressing time.

The channel number 1 indicates any one of channels 1 to 32, and the key state ST is "0" indicating that the key is released, and "1" indicates that the key is depressed. , Key number NO indicates the number of the key of the keyboard section 1 assigned to the channel 1, and the key depression time stores the time when the key is depressed.

FIG. 9 shows an example of the assigner memory B, which has the same configuration as the above-mentioned assigner memory A.

FIG. 10 shows an example of the assigner memory C, which has the same configuration as the assigner memory A.

Next, in the above configuration, the operation of this apparatus will be described with reference to the flowcharts shown in FIGS.

FIG. 11 shows a main flowchart of the electronic musical instrument. That is, first, when a power switch (not shown) is turned on, initialization processing is performed (step S1). This initialization process initializes the registers inside the CPU 3 and the registers defined inside the RAM 5, and the ROM 4
Move the specified data stored in
Further, processing such as initializing the tone color pointer to determine an initial tone color to be emitted is performed.

When this initialization process is completed, the panel unit 2
It is checked whether or not the panel switch has been turned on (step S2). When it is determined that the panel switch is turned on, the tone color pointer is changed according to the contents of the turned-on switch (step S3),
Then, it returns to step S2 and repeats the same operation again.

On the other hand, when it is determined that the panel switch is not turned on, it is checked whether or not the key of the keyboard unit 1 has been pressed (step S4). And
If it is determined that the key has been pressed, an assign process is performed (step S5).

This assigning process is a process of assigning a tone signal generating circuit to a predetermined channel and transferring data according to tone color, touch, range, etc. to the tone signal generating circuit to instruct to start sounding. Musical sounds are emitted from the sound system 8. Then, it returns to step S2 and repeats the same operation again. The details of this assigning process will be described later.

When it is determined in step S4 that there is no key depression, it is checked whether or not the key of the keyboard unit 1 has been released (step S6). When it is determined that the key has been released, the key release process is performed (step S
7).

This key release process is a process of transferring data according to the tone color, touch, and tone range to the tone signal generation circuit and instructing the tone generation end. This enables the sound system 8
The sound output from will be stopped. Then, it returns to step S2 and repeats the same operation again. Even when it is determined in step S6 that the key has not been released, the process returns to step S2 and the same operation is repeated.

As described above, by repeating the steps S2 to S7, musical tones are emitted while changing the timbre according to the operation of the panel switch of the panel section 2 and the operation of the key of the keyboard section 1. It will be.

FIG. 12 is a flowchart showing the assigning process in step S5 of FIG.

In the assign process, first, the channel number 1 is set to "1" (step S10), and then the key state ST <l of the corresponding channel number l of the assigner memory A is set.
> Is checked (step S11). If the key state ST of the key assigned to the channel number l is "1", that is, if the key is in the depressed state, it is determined that the channel cannot be used, and the channel number l is incremented (step S13), it is checked whether or not l has become "33" (step S14). Then, "3
If it is determined that it is not "3", step S1
Returning to 1, check the key state ST <l> of the next channel.

In this way, when the channel whose key state ST is "0", that is, the channel in the unused state is found, the data is sent to the channel 1 (step S1).
2). That is, a frequency signal, a waveform number, an envelope waveform number, mode data, etc. are given to the musical tone signal generating circuit of the corresponding channel, and the musical tone signal generating circuit is driven by this, and a weak-tone component musical tone is emitted. .

On the other hand, in step S14, l is "3".
When it is determined that the number of channels is "3", it is recognized that all of the "32" channels are in use, and boosting priority processing is performed (step S15). That is, the key depression time of the assigner memory A is checked, and the sound generation is assigned to the channel of the oldest time. Then, the data is sent to that channel (step S12).

Then, the channel number m is set to "1" (step S16), and the key state ST <m> of the corresponding channel number m in the assigner memory B is checked (step S17).
If the key state ST of the key assigned to the channel number m is "1", that is, if it is already in use, it is determined that the channel cannot be used, and the channel number m is incremented (step S19),
It is checked whether m has become "33" (step S2).
0). If it is determined that the value is not "33", the process returns to step S17 to check the key state ST <m> of the next channel.

In this way, when the channel whose key state ST is "0", that is, the channel in the unused state is found, the data is sent to the channel m (step S1).
8). As a result, the tone signal generating circuit of the corresponding channel is driven, and the tone of the strong-stroke component is emitted.

On the other hand, in step S20, m is "3".
If it is determined to be "3", it means that all of the "32" channels are in use, so the boost priority process is performed (step S21). That is, assigner memory B
The key depression time is checked, and the pronunciation is assigned to the channel with the oldest time. Then, the data is sent to that channel (step S18).

Then, the channel number n is set to "1" (step S22), and the key state ST <n> of the corresponding channel number n in the assigner memory C is checked (step S23).
If the key state ST of the key assigned to the channel number n is "1", that is, if the key is already in use, it is determined that the channel cannot be used, and the channel number n is incremented (step S25),
It is checked whether or not n has become "33" (step S2).
6). When it is determined that the value is not "33", the process returns to step S23 to check the key state ST <n> of the next channel.

In this way, when a channel whose key state ST is "0", that is, a channel in an unused state is found, data is sent to the channel n (step S2).
4). At this time, if the pitch designated by the keyboard unit 1 is equal to or less than a predetermined key number, the reverberation-free striking component address (“20,000 _H ” in FIGS. 5 and 6 is greater than or equal to the predetermined key number as the address of the waveform memory 21. If so, the reverberation impact component address (“21000 _H ” in FIG. 5 and FIG. 6 is given to the tone signal generating circuit as the address of the waveform memory 21. By this, the tone signal generating circuit of the corresponding channel is driven, and the reverberation is generated. Not added,
Alternatively, the musical sound of the batting component to which reverberation is added is emitted. After that, the process returns to the main routine of FIG.

On the other hand, in step S26, n is "3".
If it is determined to be "3", it means that all of the "32" channels are in use, so the boost priority processing is performed (step S27). That is, the assigner memory C
The key depression time column of is checked and the pronunciation is assigned to the channel at the old time. Then, the data is sent to that channel (step S24).

As described above, the striking component waveform data having reverberation and the striking component waveform data having no reverberation are prepared in advance in the waveform memory 21, and when the range to be reverberated is designated by the keyboard, Since the striking component waveform data having the reverberation is read and sounded, the reverberation-added musical tone can be generated without providing the reverberation adding device, so that the structure is simple and inexpensive. Instead, it is possible to generate musical sounds that are more like natural musical instruments.

In the above embodiment, the musical tone signal is generated by using the weak tapping component, the strong tapping component and the batting component as the musical tone component, but the musical tone component may be a component other than the above.

Further, in the above-described embodiment, two types of waveform data of the striking component, that is, reverberation and non-reverberation, are provided, but waveform data of reverberation and non-reverberation of other musical tone components are prepared. It may be configured.

Further, in the above embodiment, the tone signal generating circuit for generating each tone signal is provided with a polyphonic number ("32" in the embodiment) for each tone component.
The polyphonic number is not limited to “32” and may be any number.

Further, the musical tone signal generating circuit to be prepared may be configured so that the number thereof is changed according to the tone generation time of the generated musical tone component.

For example, a musical tone signal generating circuit for generating a musical tone component signal of a weak tapping component having a relatively long pronunciation time is provided with a polyphonic number "32", and a musical tone signal for generating a musical tone signal of a strong tapping component having a relatively short pronunciation time is generated. The signal generating circuit may be provided with the polyphonic number "14", and the tone signal generating circuit for generating the tone signal of the striking component having a shorter sounding time may be provided with the polyphonic number "2". The polyphonic number for each tone component is not limited to the above number.

Further, in the above embodiment, the case where the channel allocation is performed with the boost priority when all the sounding channels are in use has been described. However, the channel allocation method is not limited to this, and, for example, low-pitched sound is generated. It goes without saying that it is possible to employ a method of sequentially deallocating from the channel producing the high tone while leaving the channel producing the tone, and various other methods.
