Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a musical sound generating device suitable for use in electronic musical instruments, automatic performance machines, etc., and particularly to a musical sound generating device suitable for use in electronic musical instruments, automatic musical instruments, etc. It's about technology.

[Summary of the Invention] The present invention stores musical instrument position information representing the position of the musical instrument for each performance hall and timbre designation information corresponding to the musical instrument in a storage means, and stores the musical instrument position information indicating the position of the musical instrument for each performance venue, and stores the musical instrument position information representing the position of the musical instrument for each performance venue, and stores the musical instrument position information representing the position of the instrument for each performance venue, and stores the musical instrument position information indicating the position of the musical instrument for each performance hall, and the timbre designation information corresponding to the musical instrument. The sound field reproduction operation is simplified by reading position information and timbre designation information from the storage means and reproducing a sound field according to the position of the musical instrument in the performance hall.

[Prior Art] Conventionally, as a technology for imparting sound effects to electronic musical instruments, effect control information for obtaining a unique sound effect (e.g. reverb effect) for each performance venue such as a "concert hall" or "jazz club" has been created in advance. It is known that when a desired performance hall is preset and a desired performance hall is selected, an acoustic effect unique to the selected performance hall is imparted to the musical sound signal based on the corresponding preset information.

[Problems to be Solved by the Invention] According to the above-mentioned conventional technology, it is possible to enjoy a performance by reproducing the acoustic effects specific to a desired performance hall, but it is difficult to reproduce a sound field depending on the position of the instrument in the performance hall. I was unable to do so and was left with a lack of sense of realism. In other words, in an actual performance venue, the sound field feeling (e.g. sound image localization, frequency components of musical sounds, magnitude of acoustic effects, etc.) depends on the type and arrangement of instruments used, etc.
However, with the above-mentioned conventional technology, it is not possible to enjoy a performance that simulates such a sound field feeling.

On the other hand, as an electronic musical instrument equipped with multiple speakers, it is possible to perform by setting the sound image localization and acoustic effects of the performance sound by operating the volume, switch, and other controls provided on the panel. something is known.

With such electronic musical instruments, it is troublesome to operate a large number of controls to obtain the desired sound field feeling, and it is especially difficult to operate a large number of controls based on the desired position of the instrument in the performance hall. It is not easy to operate the various controls to reproduce a different sound field. It is very tedious to perform these operations every time you want to assume the following.

An object of the present invention is to simplify the operation for reproducing a sound field according to the position of an instrument in each performance venue.

Or configured using a recording device.

The reading means reads out instrument position information and timbre designation information regarding the performance venue selected by the selection means from the storage means.

The conversion means converts the musical instrument position information from the storage means into musical sound parameter control information for each musical sound parameter for a plurality of musical sound parameters necessary to reproduce a sound field according to the musical instrument position, and controls these musical sound parameters. As the information, volume level control information that determines sound image localization, frequency characteristic control information that determines frequency components of musical tones, effect level control information that determines the magnitude of acoustic effects such as reverb effects, etc. can be used.

The sound source means generates a musical tone signal having a timbre according to the timbre designation information from the storage means, and can be driven by either performance information based on keyboard operations or performance information read from a memory or the like.

The control means controls a plurality of parameters corresponding to the plurality of musical tone parameters of the musical tone signal generated from the sound source means in accordance with a plurality of musical tone parameter control information from the conversion means.

The sound generating means reproduces a sound field corresponding to the selected musical instrument position in the performance hall by producing sound signals controlled by the control means through a plurality of sound generating channels (for example, sound generating channels arranged left and right).

[Function] According to the configuration of the present invention, when a desired performance hall is selected,
Since the sound field is reproduced according to the position of the instrument in the performance hall, you can enjoy a performance with a rich sense of realism.

Further, since the tone color and a plurality of tone parameters are automatically set in conjunction with the selection of the performance venue, there is no need to manually set these parameters, and the operation is extremely simple.

Main Routine (Figure 8) Figure 8 shows the flow of processing of the main routine.
This routine starts when the power is turned on.

First, in step 80, an initialization routine is executed to initialize various registers. Then, the process moves to step 82.

At step 82, MOD is set to 0 to set the normal performance mode. Furthermore, the light emitting element PML is turned on based on MOD=O.

Next, in step 84, it is determined whether the value of MOD is 0 or 2 (performance mode), and if the result of this determination is affirmative (Y), the process moves to step 8B.

In step 8B, the keyboard circuit 12 determines whether there is a key-on event on any of the keys, and if the result of this determination is affirmative (Y), the process moves to step 8, where generation processing is performed, that is, the key-on event is detected. A key-on signal and key data corresponding to a pressed key are supplied to a sound source corresponding to the keyboard, and a musical tone corresponding to the pressed key is generated.

When the process of step 88 is completed or the determination result of step 86 is negative (N), the process moves to step 80, and it is determined whether there is a key-off event in any Mg1. If this judgment result is positive (Y), step 9
Moving to step 2, muting processing is performed, that is, a key-off signal and key data corresponding to key release are supplied to the sound source corresponding to the keyboard where the key-off event occurred, and the musical tone corresponding to the released key starts attenuating.

When the process of step 32 is completed or step 84
Alternatively, if the determination result in step 80 is negative (N), the process moves to step 94, and it is determined whether there is an on event in any of the performance hall selection switches HSS. If the result of this determination is affirmative (Y), the process moves to step 8B, and the H3S ON subroutine is executed as will be described later with reference to FIG.

When the process of step 96 is completed or the determination result of step 94 is negative (N), the process moves to step 98 and other processes (for example, processes corresponding to setting operations for tone, volume, etc.) are performed. .

After this, the process returns to step 84 and the subsequent processes are repeated in the same manner as described above.

H3S ON Subroutine (FIG. 9) FIG. 9 shows the H3S ON subroutine. In step 100, the number n of the turned-on switch 1 (55) is set to SNO. Then, the process moves to step 102.

This is a case where the switch H3S of number n is turned on while the sound field of the performance hall corresponding to number n is being reproduced. In this case, the reproduction performance mode is canceled and the mode returns to the normal performance mode.

If the determination result in step 102 or 104 is negative (N), the process moves to step 108, where MOD is set to 1 and PML is turned off. As a result, if step 108 is reached from step 1G2, the mode will be shifted from the normal performance mode to the instrument position setting mode, and if step 104 is reached to step 108, the mode will be shifted from the reproduction performance mode to the instrument position setting mode. K becomes.

Next, in step 110, 5FLn is set to 1, and the corresponding light emitting element DSL is turned on. Further, flags SFL other than 5FLn are set to O, and the corresponding light emitting elements H3L are turned off. As a result,
The fact that the performance hall corresponding to the turned-on switch H5S has been selected is indicated by the lighting of the light emitting element corresponding to number n.

At step 120, a sound image movement subroutine is executed as will be described later with reference to FIG. 11, and then the process returns to the routine of FIG.

Sound image initialization subroutine (Fig. 1O) Fig. 10 shows the sound image initialization subroutine, and step 122
Now, reverb control data RVD is read from the RAM 20 and set in the reverb circuit 84. When reading data RVD, H5 is added to [HADo +3+Ko].
By adding the number of bytes LO of YD, the start address of RVD is specified, and the number of bytes MQ of RVD is read.

Next, in step 124, the control variable i is set to 1. Then, the process moves to step 12B, and it is determined whether i>3.

If the result of this determination is negative (N), the process moves to step 128.

In step 128, the timbre designation data TSD of the musical instrument i is read from the RAM 20 and set in the i-th tone source TGi. When reading data TSD, [HADl
+3+ to +] to I SYD byte number L! After step 128, in which the start address of the TSD is specified and the number of bytes M1 of the TSD is read, the process moves to step 130.

In step 130, a characteristic setting subroutine is executed as described below with reference to FIG. Then, in step 132, the value of i is incremented by 1, and then the process returns to step 12B, and the subsequent processing is repeated until i>3.

When i>3, it means that the timbre setting process and characteristic setting process for the three instruments have been completed, and in response to the affirmative determination result (Y) in step 12Ei, the process returns to the routine of FIG. 9.

Subroutine for sound image movement (Fig. 11) Fig. 11 shows a subroutine for sound image movement.The stay 140 determines whether there is musical instrument position data (coordinate values x, y) from the touch panel 34B, and displays the result of this determination. If is affirmative (Y), the process moves to step 142.

In step 142, the control variable I is set to 1. and,
Proceeding to step 144, it is determined whether the coordinate values x and y are within the instrument display frame FLM of instrument i. If this determination result is affirmative (Y), the process moves to step 14B.

STEP 14B is RAM20 (F) Memory Bojo Xi
.

The coordinate values x and y are written in Yi, respectively, and the process moves to step 148, where the display position of the musical instrument i on the display panel 34A is changed according to the coordinate values of X i and Y i.

Thereafter, in step 150, a characteristic setting subroutine is executed as described later with reference to FIG.
Determine whether there is data from 4B. If this determination result is affirmative (Y), the process returns to step 148 and the subsequent processes are repeated in the same manner as described above.
If you change the touch position while touching , the contents of X f and Y i are rewritten in accordance with the change in the touch position, and the display position of instrument i on the panel 34A is also changed.

If the determination result in step 152 is negative (N), the process returns to step 140 and the subsequent processes are repeated in the same manner as described above.

For example, after setting the position of instrument l as described above,
When you touch the panel 34B to set the position of musical instrument 2, you will go to step 144 via steps 140 and 142, but the determination result of step 144 at this time is that there are X and 7 in the instrument display frame FLM of musical instrument 2. So,
The result is negative (N), and the process moves to step 154.

In step 154, the value of i is increased by 1. and,
Proceeding to step 15B, it is determined whether i>3.

In this example, since i=2, the determination result in step 156 is negative (N), and the process returns to step 144.

In step 144, since x and y are within the FLM of musical instrument 2, the determination result is affirmative (Y).After this, the position of musical instrument 2 is changed by performing the processing from step 146 onwards in the same manner as described above. is possible and becomes seven.

After this, in order to set the position of instrument 3, move to panel 3.
If you touch 4B, you will go through steps 140 and 142 to step 144, and then step 154 and 15B.
Once the process has been completed twice, the determination result in step 144 becomes affirmative (Y), and the position of the musical instrument 3 can be changed by performing the processes from step 148 onwards in the same manner as described above.

If you touch a location on the panel 34B that does not correspond to any of the instrument display frames FLM, step 154
If it passes through three times, the judgment result of step 156 is positive (Y).
Then, the process returns to step 140. Also, panel 313B
If the user has not touched , the determination result in step 140 is negative (N), and the process moves to step 158. In step 158, it is determined whether there is an on event in the performance mode switch FMS, and if not (N), the process returns to step 140.

If the switch FMS is turned on after or before setting the position of one or more of the instruments 1 to 3 as described above, step 158
The determination result becomes affirmative (Y), and the process moves to step 1eO.

In step 160, MOD is set to 2, and
The light emitting element PML is turned on. Then, the process returns to the routine shown in FIG. As a result, the instrument position setting mode is shifted to the reproduction performance mode, and manual performance (or automatic performance) can be performed while reproducing the sound field of the selected performance venue.

Note that the newly set instrument positions (the contents of Xi and Yi after being rewritten) in steps 148 to 152 may be transferred to a floppy disk in the device 24 and stored therein.

Figure 12 shows a characteristic setting subroutine. In step 170, the coordinate value X stored in xl is divided by the length W shown in Figure 3 to obtain the normal The normalized value Px is set in PX, and the normalized value Py obtained by dividing the coordinate value y stored in Yi by the length H shown in FIG. 3 is set in PY.

Next, in step 172, the contents of PX and PY (PX and py) are converted into five types of musical tone parameter control information PD (first to fourth multiplication coefficients MPI to MP4) using the ROM 18 as described in FIG. and filter constant CF), and these pieces of information are respectively set in the controlled sections of the parameter control circuit 44 as shown in FIG.

As a result, in the case of FIG. 1O, the sound field of the selected performance hall is reproduced based on the read data from the RAM 20, and in the case of Stt diagram, the sound field of the selected performance hall is reproduced based on the data read from the RAM 20. The image is reproduced based on the position setting by the position setting device 34.

After step 172, the process returns to the original routine (FIG. 1θ or FIG. 11).

[Effects of the Invention] As described above, according to the present invention, the timbre and various musical sound parameters are automatically set in conjunction with the selection of the performance hall, and a sound field is reproduced according to the position of the instrument in the performance hall. As a result, it is possible to enjoy a highly realistic performance without any troublesome setting operations.
