Description

  The present invention relates to a musical tone signal in an electronic musical instrument for percussion instrument performance that, when a percussion signal is input from a percussion input source, causes the sound generation processing device to generate a sound so that the musical tone signal of the percussion instrument is localized at a position set in the percussion instrument. The present invention relates to a control device.

For electronic musical instruments that generate multiple types of instrument sounds from stereo speakers common to each instrument sound, sound image localization control is performed by allocating the volume of each instrument sound to the left and right speakers according to the position of each instrument on the display The thing is known (refer patent document 1).
Even in an electronic musical instrument for percussion instrument performance, if the sound image localization control of each percussion instrument sound is performed, the performer can perform with a sense of presence.

FIG. 8 is a layout diagram of pad operators in a conventional electronic drum set (electronic percussion instrument system) (see Non-Patent Document 1).
In the figure, reference numerals 101 to 110 (105 and 108 are missing numbers) denote pads (hitting operation elements). 101 is a Snare Pad, 102 is a Hi-Tom Pad, 103 is a Lo-Tom Pad, 104 is a Floor Tom Pad, and 106 is a Ride Cymbal Pad. 107 is a crash cymbal pad, 109 is a hi-hat pad, and 110 is a kick pad.

The pads 101 to 110 are arranged around the performer using support columns and joints. Many of the pads 101 to 110 are provided with a plurality of trigger input sources (batting input sources) according to the place where the pad is struck and the playing style. For example, the snare pad 101 includes a rim shot, a head shot, and the like.
Reference numeral 111 denotes an electronic musical instrument for percussion instrument performance, which is a main body of the illustrated electronic drum set. Each of the plurality of input terminals (the total number of input terminals is 15 for example) and each of the pads 101 to 110 are connected by a cable. Although the terminal numbers are shown in FIG. 8, there are also input terminals to which pads are not connected.
On the other hand, the stereo output terminal of the percussion instrument playing electronic musical instrument 111 is connected to the left speaker 112 and the right speaker 113 via a power amplifier (power amplifier) (not shown).

For example, when a player strikes the kick pad 110, a batting signal is output from the trigger input source of the kick pad 110 to the terminal number 10. When there are a plurality of trigger input sources on one pad, it is possible to identify which trigger input source the trigger signal is from.
The electronic musical instrument 111 for playing a percussion instrument generates a hit sound signal of a kick drum assigned to the kick pad 110, and performs sound image localization control on the hit sound signal. In this way, the electronic musical instrument 111 for percussion instrument performance is made to sound as if the percussion sound signal of the kick drum is sounding at the sound generation position (localization position) set on the kick drum.

  On the other hand, when a performer plays an actual drum set of an acoustic drum instead of an electronic drum set, when a percussion instrument is struck, the percussion sound generated from this percussion instrument passes through the air or the support to another percussion instrument. And other percussion instruments resonate. For example, when the performer strikes a kick drum, a snare drum or a tom generates a resonance sound. In the drum kit of an acoustic drum, this resonance sound gives the drum kit a sense of unity.

However, the sound source of the electronic musical instrument 111 for percussion instrument performance described above does not have such a resonance sound waveform as a sound source waveform, or uses a percussion sound mixed with a resonance sound as a sound source waveform.
In the latter case, the resonance sound is also generated, but it sounds as if the resonance sound and the striking sound are generated from the same localization position.
The reason is that when the kick drum is struck, the resonance sound of other percussion instruments is sampled and recorded as part of the sound of the kick drum and stored as a monaural sound source waveform.
As a result, when the kick pad 110 is struck, resonance sounds of other percussion instruments such as a snare drum and a tom can be heard from the localization position of the kick drum that generates the percussion sound. For this reason, there is a problem that the localization position becomes unnatural even if the resonance sound is generated.

According to a third aspect of the present invention, in the musical tone signal control apparatus according to the second aspect, the setting data storage means has a resonance sound of at least one other percussion instrument with respect to the volume of the percussion sound signal of the percussion instrument. Relative volume data defining the volume of the signal is stored, and the hitting sound signal control means obtains volume data corresponding to the hitting force of the hitting signal, and the volume data is used as the volume of the hitting sound signal. The resonance signal control means obtains volume data corresponding to the striking force of the percussion signal, and refers to the setting data storage means so as to instruct the other sound output processing device Relative volume data defining the volume of the resonance signal of at least one percussion instrument is acquired, and the other small volume data is acquired based on the acquired volume data and the acquired relative volume data. Kutomo one percussion, and outputs the volume data of the resonance sound signal to the sound processing apparatus.
Therefore, by using the stored setting data, it is possible to easily acquire the volume data of the resonance signal of other percussion instruments set to resonate with the percussion instrument assigned to the percussion input source.

  In the musical tone signal control apparatus according to claims 1 to 3, the function of the hitting sound signal control means and the function of the resonance sound signal control means are respectively set as a hitting sound signal control step and a resonance sound signal control step. It can be realized by a musical sound signal control program to be executed by a computer.

FIG. 1 is a block diagram showing a functional configuration of an embodiment of the present invention.
In the figure, reference numerals 1 to 10 denote a plurality of batting operators, which correspond to the pads 101 to 110 in FIG. 8 and include at least one batting input source. The illustrated batting operator 1 includes two batting input sources 1-1 and 1-2. The illustrated batting operators 2 to 10 are provided with one batting input source, and therefore, the batting input source is also given the same reference numerals 2 to 10 as the batting operation device.
A percussion instrument is assigned to each of the plurality of percussion input sources 1-1, 1-2, 2-10. Normally, one acoustic percussion instrument is assigned to one percussion operator.

When a trigger signal (blow signal) is input from a certain hit input source, the hit signal detection unit 11 specifies data for specifying the hit input source that has output this hit signal, for example, the hit input source number (1-1, 1 -2, 2 to 10) and a striking signal with sound volume data representing the striking force is output to the tone signal control unit 12.
The musical sound signal control unit 12 receives the percussion signal described above, and refers to percussion instrument system setting data stored in the percussion instrument system setting data storage unit 13 when a percussion signal is input from a certain percussion input source.
The tone signal control unit 12 causes the tone generation processing unit 14 to generate a tone signal of a percussion instrument, and based on the localization position data of the percussion instrument, the tone signal of the percussion instrument is localized at a position corresponding to the percussion instrument. Let me pronounce it.
The stored contents of the percussion instrument system setting data storage unit 13 will be described later with reference to FIG.

The illustrated sound generation processing unit 14 includes a plurality of tone signal generation units 23 ₁ to 23 _n , a plurality of sound image localization control units 24 _{1 to} 24 _n , and an audio mixer 25.
The musical tone signal generators 23 ₁ to 23 _n use the musical tone signal of the percussion instrument instructed by the musical tone signal controller 12 based on the sound source waveform stored in the sound source waveform storage unit 15 and the volume corresponding to the designated volume data. And output to the corresponding sound image localization control units 24 _{1 to} 24 _n of the same subscript.
The tone signal generators 23 ₁ to 23 _n shown in the drawing generate monaural tone signals. The sound image localization control units 24 _{1 to} 24 _n cause the generated musical tone signal of the percussion instrument to be localized and sounded at the position set in the percussion instrument designated by the musical tone signal control unit 12. Specifically, the sound image localization control units 24 _{1 to} 24 _n distribute the monaural musical sound signal to the left and right output channels at different volumes according to the localization position data, thereby determining the left and right sound image localization (pan) of the musical sound signal. Control.

The audio mixer 25 mixes (mixes) the stereo signals of the sound image localization control units 24 _{1 to} 24 _n for the left and right channels, and mixes the left channel signal and the right channel signal with a power amplifier (not shown). To the left speaker 16 and the right speaker 17, respectively.

The subscripts (positive integers) in the tone signal generators 23 ₁ to 23 _n and the sound image localization controllers 24 _{1 to} 24 _n described above represent the numbers of the sound channels that are simultaneously sounded. The total number of channels that simultaneously perform sound generation processing (simultaneous sound generation number) changes every moment depending on the proximity of a plurality of hit signals, the number of resonance sounds, and the like.
The sound generation processing unit 14 has a capability of simultaneously processing sound channels having a maximum simultaneous sound number N or less, and the simultaneous sound number is limited to the maximum simultaneous sound number N or less.

The musical sound signal control unit 12 includes an impact sound signal control unit 21 and a resonance sound signal control unit 22.
When the batting sound signal control unit 21 inputs the batting signal accompanied by the batting input source number and the volume data via the batting signal detection unit 11, the batting sound signal assigned to the batting input source is the above-described batting sound signal. The sound generation processing unit 14 is controlled so that the sound is localized at the position set for the percussion instrument at a sound volume corresponding to the sound volume data.

More specifically, the percussion sound signal control unit 21 described above refers to the percussion instrument assigned to the percussion input source by referring to the percussion instrument system setting data storage unit 13 and the localization position data ( PAN).
The percussion sound signal control unit 21 instructs the tone signal generation units 23 ₁ to 23 _n of the sound generation processing unit 14 to generate the percussion instrument's acquired percussion sound signal, and uses the above-described volume data as the sound level of the percussion sound signal. Instruct.
The percussion sound signal control unit 21 also performs the above-described musical sound signal generation units 23 ₁ to 23 ₁ so that the generated percussion sound signal is localized and sounded at the position set in the percussion instrument in accordance with the acquired localization position data. one of 23 _n (e.g., 23 ₁₎ the sound image localization control unit 24 ₁ to 24 _n of the sound processing section 14 corresponding to the (e.g., 24 ₁₎ for controlling.
The localization position set for the percussion instrument is adjusted to the position where the assumed acoustic percussion instrument is arranged. Usually, however, the positions where the pads (percussion operators) 101 to 110 are actually arranged as shown in FIG. To match.

On the other hand, the resonance sound signal control unit 22 inputs a batting signal accompanied by the batting input source number and volume data via the batting signal detection unit 11 in the same manner as the batting sound signal control unit 21 described above.
The resonance signal control unit 22 is configured so that the resonance sound signal of at least one other percussion instrument set to resonate with the percussion instrument assigned to the percussion input source is the volume of the resonance sound signal of each other percussion instrument. The sound generation processing unit 14 is controlled so as to sound at a position set for each other percussion instrument at a volume corresponding to the data.

More specifically, the above-described resonance signal control unit 22 refers to the percussion instrument system setting data storage unit 13, so that the other percussion instrument assigned to the percussion input source is set to resonate. Defines the volume of the resonance signal of each other percussion instrument relative to the volume of the percussion sound signal assigned to the percussion instrument assigned to the percussion instrument and at least one percussion instrument, the localization position data set for each other percussion instrument Get relative volume data.
The resonant sound signal control unit 22 applies at least one of the musical tone signal generation units 23 ₁ to 23 _n (for example, 23 ₂ , 23 ₃ , 23 ₄ ) with respect to the resonance signal of the acquired at least one other percussion instrument. The generation is instructed, and the volume data of the resonance signal of at least one other percussion instrument described above is output based on the acquired volume data and the acquired relative volume data.
The resonance signal control unit 22 also generates a tone signal generation unit 23 so that the generated resonance sound signal is localized at a position set in the percussion instrument according to the acquired localization position data of other percussion instruments. The sound image localization control units 24 ₂ , 24 ₃ , and 24 ₄ of the same subscript corresponding to the musical sound signal generation units 23 ₂ , 23 ₃ , and 23 ₄ that are at least one of ₁ to 23 _n are controlled.

  The percussion instrument system setting data storage unit 13 described above correlates the plurality of percussion input sources 1-1, 1-2, 2-10 with the percussion instrument assigned to the percussion input source, and the percussion instrument and the percussion instrument. The at least one other percussion instrument set to resonate with each other, the correspondence between the percussion instrument and the localization position data set on the percussion instrument, and the volume of the percussion sound signal. Relative volume data defining the volume of the resonance signal of two percussion instruments is stored.

Each correspondence described above is preset as percussion instrument set setting data in advance.
When the performer connects the plurality of percussion input sources 1-1, 1-2, 2 to 10 and the plurality of input terminals of the percussion signal detection unit 11 with a signal cable, a preset percussion instrument set is used. In the setting data, connection is made so as to be consistent with the correspondence relationship between the percussion input sources 1-1, 1-2, 2-10 and the percussion instrument assigned to the percussion input source.
It is also possible for the performer to freely change the correspondence relationship described above instead of the preset correspondence relationship, and to make a connection so as to match the changed correspondence relationship.

FIG. 2 is an explanatory diagram showing an example of percussion instrument system setting data stored in the percussion instrument system setting data storage unit 13 of FIG.
Each correspondence described above can be stored individually. However, in the illustrated example, all correspondences are stored in a two-dimensional table format in relation to the percussion instrument assigned to each impact input source. The percussion instrument system setting data shown in the drawing does not directly indicate the allocation of the storage area in the storage device.
The first column shows the impact input sources. In the illustrated example, impact input sources 1-1, 1-2, 2-10 are prepared and arranged in numerical order.
FIG. 2 is for explanation, and does not necessarily match the actual product impact input source. For example, a real snare pad has six striking input sources, but only two striking input sources are shown.

The second column is a percussion instrument assigned to each percussion input source. In the illustrated example, the percussion instrument is specified by the instrument name, but may be specified by the percussion instrument number. Based on the description specifying the percussion instrument, the tone color of the hitting sound and the address of the hitting sound waveform in the sound source waveform storage unit 15 are designated.
When the batting operation elements 1 are common, such as the batting input sources 1-1 and 1-2, a description (rim shot, head shot, etc.) for identifying the hit portion is attached to the second row of percussion instruments. .
If no percussion instrument is assigned to a percussion input source, the second column of percussion instrument items is empty. Also, percussion instruments that are not assigned to any percussion input source have empty percussion input source items in the first column.
The third column is the localization position data (PAN) of the percussion instrument in the second column. The numerical values shown in the figure are the same as PAN used for sound image localization control in the MIDI standard, and the range is from 0 to 127, with 0 corresponding to the left, 64 corresponding to the center, and 127 corresponding to the right localization. .
In the case of the batting input sources 1-1 and 1-2, since the batting operator is a common snare pad, the localization position data takes the same value.

The fourth column is another percussion instrument set to resonate with each percussion instrument in the second column, and when there is at least one such other percussion instrument, a percussion instrument name or percussion instrument for identifying these percussion instruments It is described with numbers. When there is no percussion instrument that resonates with respect to the second row of percussion instruments, the items of other percussion instruments that resonate in the fourth row are empty.
Based on the description specifying the resonating percussion instrument, the tone color of the resonance sound and the address of the resonance sound waveform in the sound source waveform storage unit 15 are designated.
The fifth column is relative volume data defining the volume of the resonance sound signal of at least one other percussion instrument set to resonate in the fourth column with respect to the volume of the percussion sound signal of the second column. .

The fourth row of resonating percussion instruments “kick” for the second row of percussion instruments “floor tom”, and the fourth row of resonating percussion instruments for the second row of percussion instruments “kick” for the relative volume “20” of the fifth row. The relative volume of the fifth column of “floor tom” is “35”, and the relative volume value when the percussion instrument and the percussion instrument resonating with each other are replaced does not match. However, even if the percussion instrument resonating with the percussion instrument is replaced, the relative volume may be set to be the same, and the relative volume may be set symmetrically.
In addition, when a percussion instrument that resonates with a percussion instrument that generates a percussion sound is now a percussion instrument that generates a percussion sound, the percussion instrument that generates the percussion sound is a percussion instrument that generates a resonance sound. . However, a setting that does not occur in this way is also possible.

In the illustrated example, the relative volume of the percussion instrument that resonates is determined by the combination of the percussion instrument that generates the percussion sound and the percussion instrument that resonates. However, the performer can change the relative volume setting according to the actual arrangement of the pads or the arrangement of the acoustic percussion instrument system.
Note that the localization position data for the percussion instrument that resonates in the fourth column is acquired from the localization position data in the third column because the resonance sound and the percussion sound of the percussion instrument are localized at the same position. For example, the localization position data of the resonating percussion instrument “kick” is equal to the localization position data “100” in the third column for the percussion instrument “kick” in the second column.
The percussion sound of the percussion instrument changes according to the position where it is struck, but the percussion instrument resonates as a whole. Therefore, the percussion instrument in the second column is limited to the part to be hit, but is described as a parameter that can also identify the percussion instrument itself.
On the other hand, the percussion instrument description in the second column may not be able to identify the percussion instrument itself as long as the corresponding relationship between the resonating percussion instrument and its localization position is also stored in the percussion instrument system setting data storage unit 13.

With reference to FIG. 2, a supplementary explanation will be given regarding the generation rule of the resonance sound.
The setting of the percussion instrument to be resonated and the setting of the relative volume data of the resonance signal are determined by the degree of correlation between the vibration frequency characteristics of the percussion instrument that generates the percussion sound and the percussion instrument that resonates with the percussion sound.
For example, the hit sound of “snare (rim shot)” assigned to the hit input source 1-1 is “high tom”, “rotum”, “floor tom”, “hi-hat”, “ It resonates with “crash cymbal” and “ride cymbal”, and in particular, the resonance sound of “high tom” is the largest, and the relative volume data is “20”.
On the other hand, when the “snare (headshot)” assigned to the strike input source 1-2 is struck, it resonates with “high tom”, “rotum”, and “floor tom”, and particularly the resonance sound at “high tom” is the largest. The relative volume data is “20”.

Here, the resonance sound signal of the resonating percussion instrument is made common regardless of the original percussion instrument that generated the percussion sound, thereby reducing the memory capacity of the sound source waveform storage unit 15.
That is, in FIG. 2, as a percussion instrument that resonates with the percussion instrument “snare (rim shot)”, the percussion instrument “snare (headshot)”, and the percussion instrument “kick” in the second row, the common “high tom” in the fourth row. Is described. As a percussion instrument that resonates, a common resonance waveform is used as a sound source waveform by instructing the sound generation processing unit 14 of the fourth column “Hytom”.
Alternatively, the resonance signal of another percussion instrument that resonates can be made different depending on the percussion instrument that generated the original percussion sound. For example, in FIG. 2, different resonance sound waveforms are used as the sound source waveform in accordance with the combination of the second row of percussion instruments and the fourth row of resonating percussion instruments.

The resonating percussion instrument “snare” in FIG. 2 is appended with “(including buzz sound)”.
An acoustic “snare drum” has a “snappy” touching the head on the back. This “snappy” vibrates freely by the performance of another acoustic percussion instrument, and the musical sound generated at this time is called “snappy buzz sound”. The “snare (including buzz sound)” refers to a resonance sound including such a “snappy buzz sound”.
This “snappy buzz sound” is affected by the “snappy” tension in an acoustic “snare drum”. Therefore, even in electronic percussion instruments, by changing the “snappy” setting operation in multiple stages from “snappy” tightly to “snappy” loosely, different resonance sound waveforms “short snappy buzz sound” ”To“ long snappy buzz ”and“ the state where the snappy is removed (off) ”may be selected.
Although explanation is omitted, even for the “snare drum” hitting sound, different hitting sound waveforms are set and different hitting sound signals are generated by the multi-step setting operation of “snappy”. .

In the sound source waveform storage unit 15, a percussion sound waveform for generating a percussion sound having the tone of a percussion instrument, instructed by the percussion sound signal control unit 21, and other resonant units instructed by the resonance sound signal control unit 22. A resonance sound waveform for generating a resonance sound having the tone of a percussion instrument is stored.
One method for creating such a striking sound waveform and a resonance sound waveform will be described below.
The acoustic percussion instrument set to be recorded is assumed to be a musical instrument arrangement similar to the pad arrangement of the electronic percussion instrument system shown in FIG. A microphone for monaural recording is set up at each position of each acoustic percussion instrument.

Hit one target percussion instrument. At that time, the recording is divided into a case where the vibration plates are damped so that all of the other percussion instruments do not resonate and a case where the vibration is not resonated except for one of the other percussion instruments.
The percussion sound recorded by the microphone at the position of one target percussion instrument when all other percussion instruments do not resonate is used as the percussion sound waveform of one target percussion instrument.
Regarding the resonance sound of a certain resonating percussion instrument when a target percussion instrument is struck, first, the position of one resonating percussion instrument described above when all the percussion instruments that are not percussed do not resonate. The sound of hitting is recorded with the microphone. Further, when no resonance is made except for the one resonating percussion instrument described above, the resonance sound is recorded by the microphone at the position of the one resonating percussion instrument described above.
The latter resonance sound is mixed with striking sound. Therefore, based on the subtraction of the former percussion sound from the latter resonance sound, the resonance sound waveform of a certain resonating percussion instrument described above is created.
When the resonance sound waveform is made common without distinguishing the original percussion instrument that generated the percussion sound, the average of the resonance sound waveforms of one resonating percussion instrument created above for each percussion instrument to be percussed is used. Use it.
Note that the recording of resonance can be omitted. In this case, the percussion sound of each recorded percussion instrument is directly used as a resonance sound waveform. Further, it is more preferable that the waveform of the rising portion (attack) of the percussion sound of each recorded percussion instrument is a resonance sound waveform.

The striking sound waveform and the resonance sound waveform are normalized so that the sound volume is constant.
The relative sound volume data of the resonance signal is set based on the percussion sound before normalization and the volume level of the resonance sound.
The value of the localization position data (PAN) is set so that the percussion sound can be heard from the position where the acoustic percussion instrument is arranged.

The sound system 52 is realized by, for example, a DSP (Digital Signal Processor), and outputs a stereo signal that is subjected to sound image localization control according to the input localization position data with respect to a musical sound signal generated by the sound source 51. The stereo signal is output to a stereo speaker or stereo headphone 33.
The tone signal generators 23 ₁ to 23 _n shown in FIG. On the other hand, the functions of the sound image localization control units 24 _{1 to} 24 _n and the audio mixer 25 may be realized in the sound source 51 or the sound system 52.

The function of the tone signal control unit 12 shown in FIG. 1 is realized by the CPU 42 executing a computer program using the RAM 44, the timer 45, and the like.
FIG. 4 is an explanatory diagram of a specific example of the pronunciation table stored in the work area in the RAM 44 shown in FIG. This sound generation table represents the interrelationship of various musical tone control parameters used by the CPU 42 to realize the functions of the musical tone signal control unit 12 in FIG. 1, but does not show the allocation of the storage area in the RAM 44 as it is. Absent.
When a striking signal is input from one of the plurality of performance operators 32, the CPU 42 assigns a sounding channel to the striking input source that has output this striking signal, and sets a temporary storage area for musical tone control parameters in the sounding table. give.
The CPU 42 instructs the sound source 51 to generate the striking sound signal and the resonance sound signal by transferring the tone control parameters stored in the sound generation table, and at the same time controls the sound image 52 to control the sound image. Let

In the specific example of FIG. 4, a batting signal is input from each of batting input sources 1-1, 1-2, 10, 2, 3, and 4, and “snare (rim shot)”, “snare (head shot)”, Six striking sounds of “kick”, “high tom”, “rotam”, and “floor tom” are being generated by the sound source 51 generating musical tone signals.
Here, the relationship between the percussion input source and the percussion instrument that generates the percussion sound is acquired with reference to the percussion instrument system setting data of FIG.

When the hitting signal described above is input, the CPU 42 also assigns a sound generation channel to the resonating percussion instrument to generate a resonance sound, and gives an area for temporarily storing parameters in the sound generation table, and the sound source 51 and sound. The parameters temporarily stored in the sound generation table are transferred to the system 52 to instruct generation of a resonance signal, and at the same time, sound image localization control is performed.
The resonating percussion instrument described in relation to each percussion instrument in FIG. 4 is acquired with reference to the percussion instrument system setting data of FIG.
In the example shown in the figure, the percussion instrument “snare (rim shot)” has six percussion instruments that resonate: “high tom”, “rotum”, “floor tom”, “hi-hat”, “crash cymbal”, and “ride cymbal”. Resonance sound is being generated as a tone signal is generated by the sound source 51. Therefore, the total number of percussion instruments that resonate is 23 when all the percussion instruments being sounded are summed.

  Here, the resonating percussion instrument is acquired with reference to the percussion instrument system setting data storage unit 13 shown in FIGS. However, there is a case where the percussion input source corresponding to the percussion instrument that is the resonant percussion instrument is not connected to the electronic musical instrument for percussion instrument performance. Then, a batting operator that cannot be operated by the performer, that is, a percussion instrument that cannot generate a batting sound, generates only its resonance sound. Therefore, the performer may feel an unnatural musical sound.

Therefore, even if the percussion instrument resonating acquired with reference to the percussion instrument system setting data shown in FIG. 2 is not assigned as a percussion instrument that generates a percussion sound, the resonance sound is prohibited. May be.
That is, when a batting signal is input, the connection state between each performance operator (pad) 32 and the electronic musical instrument 31 for percussion instrument performance is detected. More specifically, the same percussion instrument as the resonant percussion instrument in the fourth column described in the pronunciation table shown in FIG. 4 is searched from the second column of the percussion instrument system setting data shown in FIG. If it is not assigned to one of the percussion input sources in the first column, the sounding of this resonating percussion instrument is prohibited.

Alternatively, these connection states are detected in advance, and the percussion instrument assigned to the performance operator (pad) 32 determined not to be in the connection state is excluded from the resonating percussion instruments.
More specifically, the percussion instrument that is the same as the percussion instrument in the fourth column in the percussion instrument system setting data shown in FIG. 2 is searched from the second column, and the percussion instrument is set as one of the percussion input sources in the first column. If not, remove this resonating percussion instrument from the fourth column.
In the above specific example, the operation of connecting the performance operator (pad) 32 performed by the performer to the designated input terminal of the electronic musical instrument 31 for percussion instrument performance is shown in the correspondence between the percussion instrument input source and the percussion instrument shown in FIG. Assuming that

The CPU 42 is the data of the sound source state such as the data on whether or not the musical sound signal generation processing of the percussion sound signal or the resonance sound signal in a certain sound generation channel in the sound source 51 and the current value of the amplitude envelope during the musical sound signal generation. For example, when the tone signal generation is completed, the assigned sound channel is released, and the storage area for the tone control parameters of the assigned sound channel is released from the sound generation table shown in FIG.
Alternatively, a gate time that defines a sound generation period is set for each percussion instrument, and the CPU 42 cancels the assigned sound channel as the gate time elapses without acquiring sound source state data, and stores the storage area. You may release.

The maximum simultaneous pronunciation number N is limited by the processing capability of the sound source 51. Therefore, when a new striking signal is input and a new sounding request for a striking sound and a resonance sound is received, if this sounding request is accepted, the simultaneous sounding number will exceed the maximum simultaneous sounding number N. Process. That is, the sound channel that has the least influence is selected, the sound volume of the sound channel is rapidly attenuated, the sound channel is unassigned, and the sound channel is freed. .
For example, the sounding channels are released in order from the smallest sounding amplitude value of the sounding sound signal or the resonance sound signal among the sounding sounding sound or resonance sound currently being sounded. Alternatively, the sounding channels are canceled in order from the sound of the striking sound or resonance sound that is currently being sounded, in the order of the sounding duration from the sounding start time.

The PAN described in relation to each percussion instrument in the percussion sound column, and the resonating percussion instrument and PAN described in relation to each percussion instrument in the resonance sound column are obtained by referring to the percussion instrument system setting data in FIG. Has been. As described with reference to FIG. 2, since the PAN value of the percussion sound generated by a certain percussion instrument and the PAN value of the resonance sound generated by this percussion instrument are equal, the PAN value of the resonating percussion instrument is equal to the percussion instrument. Of the percussion instruments described in the column, the PAN value corresponding to the same percussion instrument as the resonating percussion instrument is copied.
The percussion instrument volume described in relation to each percussion instrument in the percussion sound column is volume data corresponding to the percussion force acquired from the percussion signal output from the percussion input source. In the illustrated example, a numerical value of 0 to 127 is used. This value is acquired when the input interface 48 detects a hit signal.

On the other hand, the volume of the resonating percussion instrument described in relation to each resonating percussion instrument is acquired and stored according to the calculation formula shown in FIG.
First, in the percussion instrument system setting data shown in FIG. 2, the value of the relative volume of the resonance sound signal described corresponding to the resonating percussion instrument described in relation to each percussion instrument is acquired. Are multiplied by the constant 127. In other words, the value of the relative volume of the resonance signal is the volume ratio of the resonance sound to the percussion sound that caused the resonance sound, and 127 is the reference value.

FIG. 5 is an explanatory diagram showing another specific example of the percussion instrument system setting data shown in FIG. 2 and the sound generation table shown in FIG. 4 based thereon. Only percussion instrument “snare (rim shot)” data is extracted and illustrated.
FIG. 5A is an explanatory diagram of a modified example of the percussion instrument system setting data shown in FIG. FIG. 5B shows a specific example of the first state of the pronunciation table shown in FIG. 4 when the percussion instrument system setting data of FIG. 5A is used, and FIG. 5C shows the second state. It is a specific example showing.

As shown in FIG. 5A, in this modified example, the percussion instrument that produces the resonance sound is made different depending on the striking force. That is, another percussion instrument set to resonate with the percussion instrument assigned to the percussion input source is changed according to the percussion force of the percussion signal, that is, the volume data of the percussion instrument assigned to the percussion input source. It is different.
In an acoustic percussion instrument, the greater the percussion power, the greater the percussion sound and the wider the frequency spectrum of the percussion sound. Therefore, focusing on the fact that the acoustic percussion instrument that resonates also changes, the percussion instrument system setting data described above is used.

In the illustrated example, the percussion instrument volume value assigned to the percussion input source to which the percussion signal is input has a weak or medium percussion force (0 to 99 in the illustrated example), and a strong percussion force (illustrated). In this example, the setting of “other percussion instruments” to be resonated is varied according to two cases of 100 to 127).
When using the percussion instrument system setting data shown in FIG. 5 (a), the sound generation table when the percussion instrument volume value of the percussion instrument assigned to the percussion input source to which the percussion signal is input is weak or medium percussion, and The sound generation tables in the case of a strong striking force are as shown in FIGS. 5B and 5C, respectively.

  In the example shown in the figure, in the case of strong percussion force, “other percussion instrument” is newly added to “other percussion instrument” in the case of weak or medium percussion force. However, there may be a case where a part of “other percussion instrument” is not selected in the case of weak to medium impact force. The relative volume of “other percussion instrument” in the case of strong percussion is equal to the relative volume of the same “other percussion instrument” in the case of weak to medium percussion, and the newly added “other percussion instrument” The relative volume of the “percussion instrument” is smaller than the relative volume of the “other percussion instrument” in the case of a weak or medium impact force, but it does not have to be such a numerical relationship.

The electronic musical instrument 31 for percussion instrument performance shown in FIG. 3 can be provided with an automatic performance function for music data. Generation of a musical tone signal based on the automatic performance data in this case can also be realized in the sound source 51. However, there is a difference between the generation of a musical sound signal based on automatic performance data and the generation of a percussion instrument sound signal. Therefore, an automatic performance sound source (not shown) different from the sound source 51 may be provided. Similarly, when the electronic musical instrument 31 for percussion instrument performance has a keyboard performance function, a sound source different from the sound source 51 may be provided. The sound source for keyboard performance and the sound source for automatic performance may be the same.
The CPU 42 is involved in any processing of percussion instrument performance, automatic performance, and keyboard performance. The tone signal based on the automatic performance data and the tone signal based on the keyboard performance are mixed with the percussion instrument sound signal in the sound system 52.

The electronic musical instrument 31 for percussion instrument performance described above includes a sound source 51 and a sound system 52.
However, even if these are not incorporated, the function of the tone signal control unit 12 shown in FIG. 1 can be realized. In this case, the sound source and sound system of the external performance device 34 are used. The striking sound waveform and the resonance sound waveform stored in the sound source waveform storage unit in FIG. 1 are stored in the sound source in the external performance device 34.

  There is also an electronic keyboard instrument (for example, a portable synthesizer) provided with a plurality of performance operators (pads) 32 on an operation panel. Even in such an electronic keyboard instrument, the function of the tone signal control unit 12 shown in FIG. 1 can be realized. In this case, the plurality of performance operators 32 are arranged in a narrow area called an operation panel. However, the sound image localization control can be performed so that the percussion sound and the resonance sound output from the stereo speaker (stereo headphones) 33 are generated from the localization position corresponding to the wide arrangement of the assumed acoustic percussion instrument set.

  Furthermore, the sound source 51 and the signal processing function in the sound system 52 described above can also be realized by the CPU 42 executing a software program (so-called software sound source program). In this case, the above-described percussion instrument playing electronic musical instrument 31 can be realized by a personal computer including an input interface 45 having a plurality of performance operator input terminals, a D // A converter, an amplifier, a stereo output terminal, and the like. .

FIG. 6 is a flowchart showing an example of an operation for realizing the musical tone signal control unit 12 in the embodiment shown in FIG. 1 using a computer (CPU 42 in FIG. 3). FIG. 6A is a main flowchart, and FIG. 6B is a flowchart of timer interrupt processing.
The flowchart of FIG. 6A starts when the electronic musical instrument 31 for percussion instrument playing is turned on, and is repeatedly executed until the power is turned off. In S51, various setting data of the percussion instrument playing electronic musical instrument 31, for example, the percussion instrument system setting data shown in FIG. 2 is initialized. In S52, in response to an operation of the setting operator 49 by the performer, setting operations of various functions corresponding to the operation are performed. In S53, other processes are performed, and the process returns to S52.

While the main process of FIG. 6A is being executed, a timer interrupt is performed by the timer 45, for example, every 0.5 ms.
The flowchart of FIG. 6B is activated by this timer interruption. In S61, in response to the player's hitting operation, processing corresponding to the function of the musical tone signal control unit 12 of FIG. The sound system 52 is instructed to generate a musical sound signal and to control sound image localization.

FIG. 7A is a flowchart showing the setting operator receiving process shown in S52 of FIG. 6A, and FIG. 7B is a flowchart showing the musical tone signal control process shown in S61 of FIG. 6B.
In S71 of FIG. 7A, if there is an input from the setting operator 49, the process proceeds to S72, and if there is no input, the process returns to FIG. In S72, when the setting operation is a resonance sound generation mode selection operation, the process proceeds to S73, the resonance sound generation mode is set, and the process returns to FIG.
On the other hand, if the setting operation is another operation in S72, the process proceeds to S74, and the content instructed by the other operation is set. For example, the setting of percussion instruments assigned to each of the percussion input sources 1-1, 1-2, 2 to 10 shown in FIG. 1, the master volume of the tone signal output from the audio mixer 25 of FIG. 1, and the reverb applied to this tone signal Make settings for effects such as.

Further, the percussion instrument system setting data shown in FIG. 2 is replaced with setting data of a different percussion instrument system, or each item is changed by the user's operation to create user-specific percussion instrument system setting data. It can also be stored in the storage device 46.
The above-described flowchart is based on the premise that a resonance generation ON / OFF button is provided on the panel operation surface of the electronic musical instrument 31 for percussion instrument performance.
When recording a musical sound signal output by playing a percussion instrument system, it may be better to output only the percussion sound. In such a case, the performer can prohibit the generation of resonance by the selection operation described above.

In the musical tone signal control process shown in FIG. 7B, sound channel assignment and truncation are omitted.
In S81, it is determined whether or not there is a hitting event. If there is a hitting event, the process proceeds to S82, and if not, the process returns to FIG. For example, when the input interface 48 in FIG. 3 detects a batting signal, the flag with the batting event and the volume data corresponding to the batting force are temporarily stored in the event register, and the CPU 42 refers to this register in S81. Thus, the presence / absence of an impact event is detected.

In the next S82, it is determined whether or not the resonance sound generation mode is set. If so, the process proceeds to S83, and if not, the process proceeds to S84. In S84, only the hitting sound is generated for the sound source 51 and the sound system 52 based on the sound generation table of FIG. 4 stored in the RAM 44 of FIG.
In next step S83, the percussion instrument playing electronic musical instrument 31 determines whether or not the music data is being played automatically. If so, the process proceeds to S84 described above, and if not, the process proceeds to S85. In S85, it is determined whether truncation processing of the sound source 51 is occurring. If so, the process proceeds to S84 described above, and if not, the process proceeds to S86. In S86, the sound source 51 and the sound system 52 are caused to generate a resonance sound together with the striking sound based on the sound generation table of FIG. 4 stored in the RAM 44 of FIG.

The above-described S83 and S85 are processes for keeping the load on the CPU 42 low and preventing a delay in the processing so that a sound generation instruction and a sound image localization control instruction are not delayed for the sound source 51 and the sound system 52.
The electronic musical instrument 31 for percussion instrument performance has less hardware resources than the personal computer, the processing capacity of the CPU 42 is inferior, and the transfer speed of the bus 41 is slow.
Accordingly, when the performer operates the performance operator 32 while automatically playing the music data in the electronic musical instrument 31 for percussion instrument performance, the CPU 42 has a high load for the musical sound signal control processing for automatic performance. Therefore, generation of a new resonance is prohibited by S83.

In addition, when the strike event occurs, if the number of simultaneous pronunciations exceeds the maximum number of simultaneous pronunciations N, truncation processing is performed, but processing for determining a sound generation channel to be deallocated becomes a load on the CPU 42. Therefore, if a plurality of resonance sounds are generated each time a hit event is detected, the load on the CPU increases. Therefore, generation of a new resonance is prohibited by S85.
In addition to the processing of S85 described above, in the truncation processing itself, as a method of selecting a sound generation channel to be unassigned, a sound generation channel generating a resonance sound is more preferable than a sound generation channel generating a striking sound. The assignment may be canceled with priority.
If the hardware resources of the electronic musical instrument for percussion instrument performance are sufficient, steps S83 and S85 described above are not necessary.

In the above description, the sound image localization of the striking sound signal and the resonance sound signal has been realized by distributing the volume of the monaural striking sound signal and the resonance sound signal generated as the musical sound signal to the left and right audio channels.
Instead of this, if a stereo striking sound waveform or a resonance sound waveform is used as the sound source waveform, a stereo striking sound signal and a resonance sound signal that are synthesized with each other may be simply output to the left and right audio channels. In this case, the sound image localization control units 24 _{1 to} 24 _{n of} FIG. 1 are not necessary, and the percussion instrument system setting data shown in FIG. 2 and the localization position data (PAN) in the sound generation table shown in FIGS. The setting of is no longer required.
