Description

[Detailed Description of the Invention] Appearance 1 This invention relates to an electronic musical instrument suitable for acoustic education or music education, and particularly to an electronic musical instrument that is capable of independently controlling volume, pitch, and other musical sound elements for each note name. About electronic musical instruments.

Previously, the @ amount or bit adjustment on electronic musical instruments was done uniformly for all note names. Further, the notes 111 or scales that can be played are limited to equal temperament or just key, and the player cannot freely create any temperament or scale. On the other hand, for music education or pitch education, it is desirable to have various special functions not generally required of electronic musical instruments for normal performance. For example, if the pitch could be adjusted independently for each note name, it would be useful for listening to scale deviations and developing a correct sense of scale, and it would be useful to be able to adjust the pitch independently for each pitch name, and it would also be useful for listening to scale deviations and developing a correct sense of scale. It is meaningful in music education because it allows you to create a musical temperament or scale. Also, if you can adjust the volume independently for each note name, you can emphasize or weaken a specific note name in the scale.
This is meaningful in music education, and is also advantageous in controlling the number of scale notes by deleting unnecessary note names when creating an arbitrary scale. Of course, not only for educational electronic instruments but also for ordinary electronic instruments, if the volume or pitch could be controlled independently for each note name, it would be possible to create the player's favorite temperament or scale, or adjust the volume. Emphasize a specific note name by increasing or decreasing it! It is useful because it can enhance the musical effect by weakening the stiffness (for example, emphasizing the tonic and other main notes of the key when playing chords). However, not only ordinary electronic musical instruments but also electronic musical instruments for educational purposes have not been able to independently control the pitch and tone m for each pitch name fO.

11 This invention has been made to fulfill the above requirement, and aims to provide an electronic musical instrument in which the volume, pitch, and other musical tone elements can be independently controlled for each note name. Another object of the present invention is to create a new musical scale (sue''- (1) It is an object of the present invention to propose a preset function to improve operability in independent adjustment of musical tone elements for each note name.A further object of the present invention is to propose a preset function for adjusting the volume, pitch, etc. independently for each note name. An object of the present invention is to provide an electronic musical instrument that has been variously improved by controlling musical sound elements.

The outline of this invention will be explained with reference to Fig. 1.
Pitch name specification means 1 for specifying the pitch name of the musical tone to be generated
A tone signal generating means 2 is provided to generate a musical tone signal corresponding to the tone name specified by the tone name specifying means 1. Operator means 3 is provided to independently adjust at least one of the volume, pitch, and other musical sound elements for each note name, and adjusts the musical sound elements of the musical sound signal that should not be generated by the musical sound signal generating means 2 into the musical sound signal. A control means 4 is provided to independently control each combination according to the contents adjusted by the operator means 3 corresponding to the note name. In this configuration
At least one of the musical tone elements of Bitchi no Haku, such as the volume, can be controlled independently for each note name, and the above-mentioned purpose can be achieved. The operator means 3 can independently adjust the volume or pitch or any one or a plurality of other musical sound elements (for example, timbre or modulation effect) for each pitch name phrase. I can do it.

To achieve another object of the invention, presetting means 5 are added as shown in FIG. The prelet means 5 makes it possible to collectively select a set of data for adjusting musical tone elements (at least one of the volume, pitch, and pitch elements) for each preset note name. In this case, the control means 4 selects the musical tone elements of the musical tone signal corresponding to each note name according to the data for each note name adjusted by the operator means 3 or the data for each note name selected at once by the preset means 5. control.

As an example, as shown in FIG. 2, the operator means 3 stores an operator 3a provided corresponding to each note name and adjustment details for each note name, and responds to the operation of the operator 3a. The storage means 3b includes a storage means 3b whose stored contents are changed by changing the stored contents thereof, and a display means 3c for displaying adjustment contents for each pitch name stored in the storage means 3b. The preset means 5 also includes a preset storage means 5a capable of storing a plurality of sets of musical tone element adjustment data for each note name, and a musical tone element adjustment for each note name adjusted by the operator means 3. It includes a writing means 5b for writing a set of data into the preset storage means 1 to 5a, and a succession means 5C for selectively reading out a set of tone element adjustment data from the preset storage means 5a. .

A set of tone element adjustment data read from the preset storage means 5a is written into the storage means 3b of the operator means 3. The control means 4 is given the data stored in this storage means 3b. However, the specific configurations of the operator means 3 and the brilet means 5 are not limited to those illustrated in FIG. 2, and are known in the field of electronic musical instruments as operator devices or preset devices for setting and selecting various data. The configuration can be applied as appropriate.

- By way of example, the operator means 3 may include functions such as those shown in FIG. That is, there is an operator 3d for independently adjusting the volume and at least one other musical tone element (for example, pitch 4) for each note name, and the adjustment contents for each note name of each musical tone element. A display means 3e for displaying a display, and a display system that detects a note name whose volume has been adjusted to zero and forcibly displays the adjustment contents of other musical tone elements corresponding to the note name in a predetermined clear display. 1 means 3f and /υ. Naturally, musical tone signals corresponding to note names whose volume has been adjusted to zero are not produced. Therefore, in that case, even if other musical tone elements are adjusted to some value corresponding to the note name, effective musical tone control will not be performed in accordance with the adjustment contents. It is unreasonable and unkind to the player to display the adjustment details of musical tone elements even though effective musical tone control is not possible. Therefore, by performing a predetermined clear display, it is made known that effective control cannot be performed on other musical tone elements due to the volume being zero. Such display control is particularly advantageous when the display means 3e is shared between the volume and other musical tone elements. That is, when the display means 3e is used to display the adjustment contents of other musical tone elements, the volume is not displayed, and therefore, normally, it is not immediately possible to tell which note name is set to zero volume. However, by performing the above-mentioned predetermined clear display when displaying musical tone elements other than the volume, the name of the pitch at which the volume is zero can be immediately determined.

In order to ensure that the above-mentioned clear display control is performed only when the player's strong will is activated, the above-mentioned condition is set that an operation to lower the volume is performed during the reception after the volume has been adjusted to zero. It is recommended that clear display be performed. On the other hand, when the volume is once adjusted to zero and an operation is performed to lower the volume, the display means 3
It is preferable to change the display of the volume adjustment details in e from the normal zero display to a predetermined off display. For example, this off display may be used as a display indicating that the corresponding pitch name will not be used for the time being (it is distinct from a mere display of zero volume). - For example, if this OFF display cannot be changed by operating the suspension adjustment controls (for example, pre-ref 1 - replacing a whole set of data with the data selection operation or turning on the power switch of the electronic musical instrument) It will not be resolved unless you reset the circuit and initialize the circuit. This can be applied to cases where you want to create an arbitrary scale by deleting the note name of .

FIG. 4 conceptually shows an example in which a keyboard 1a having a plurality of keys is used as the pitch name specifying means 1, and the musical tone signal generating means 2 includes a plurality of musical tone generating tunnels. In this case, a sound allocating means 2a is provided in conjunction with the musical tone signal generating means 2, and a key pressed on the keyboard 1a is assigned to one of the channels, and a musical tone signal corresponding to the key is generated on the assigned channel. The control means 4 selects the output data of the operator means 3 corresponding to the note name of the key assigned to each channel fg for each channel fg according to the assignment by the pronunciation assignment means 2a. Musical tone elements are controlled independently for each channel according to the selected data.

In electronic musical instruments using such an allocation method, the number of channels is limited, so it is necessary to perform efficient allocation control. As mentioned above, if there is a note name whose volume is adjusted to zero, even if the key corresponding to that note name is assigned to any channel and tc, no tone signal will actually be produced in that tone channel. Therefore, it is preferable to avoid such wasteful allocation. Therefore, a volume zero detection means is provided in connection with the pronunciation assignment means 2a, and the operator means 3 detects the note name whose volume is adjusted to zero (including the note name with the above-mentioned OFF display), and The above assignment is not performed for keys that correspond to names.

Specific embodiments of this bimei will be described below with reference to the accompanying drawings.

Twelve genuine tone memories 48-1 to 48-12, each numbered from 1 to 12, are shown in FIG.
Each of the 12 famous tones of the pure tonic scale (-a) corresponds to (-a), and each pitch data and volume data for each note name of the pure tonic scale (-a) are stored in advance. In this case, the pitch data is a predetermined value that indicates, in cents, the pitch deviation of each note name of the J3 pure tonic scale with respect to equal temperament, and the interval data is a predetermined value that indicates the pitch deviation of each note name of the J3 pure tonal scale. This is an appropriate value predetermined for each tone.In genuine tones, if the key changes, the pitch will shift somewhat even if the note name is the same, so a memory for each tone is required.These genuine tones Memory 48-
1 to 48-12 are also made of ROM.

The 24 brissera 1 to 49-1 to 49-24, each numbered with sub-numbers 1 to 24, correspond to 24 brileted or preletable scales, and each of them corresponds to the 24 brileted or preletable scales. It is possible to store or store a set of pitch data and volume data for each pitch name C-B of d3L. This preset memory 4
9-1 to 49-24 consist of readable memories (for example, RAM).

One of the genuine tone memories 48-1 to 48-12 is selectively read out by the combination of the small rotary switch position 1 and the scale switch 5C1- (see Figures 7 and 9). Among the read data, one set of pitch data for each note name is stored in the PD memory in 2nd place, and one set of volume data for each note name is stored in the VD memory in 1st place. - to be done.

A set of scale data is stored in the VD memory. Prelet memories 49-13 to 49-24 numbered 13 to 24 are configured so that one memory can be selectively read out by the combination of the rotary switch position 3 and the scale switch SC'L. Among the output data, one set of pitch data is set in the PD memory, and one set of volume data is set in the VD memory. Of course, in PD memory and VD memory, when a new data set is set, old stored data is cleared.

The hold memory 50 stores the preset data set from any of the preset memories 49-1 to 49-24 (
Or from genuine tone memory 48-1 to 48-12)P
This is to save the data stored in the PD memory or VD memory up to that time when the D memory or VD memory is erased.

When you want to monitor the contents of the data stored in the preset memory, you can transfer the data from the desired preset memory to the PD memory or VD memory. Pitch data and sound file data that have been painstakingly adjusted are stored in the PD memory and VD memory, and it is not desirable for this to be cleared. In order to prevent such a situation from occurring, a hold memory 50 is provided to prevent old data stored in the D memory and VD memory from being saved.

In addition to the above-mentioned memory and register, there is a panel data memory 57 and a working memory for storing operation data of other panel section operators. The stored contents of panel data memory 57 are transferred to panel data register 33 in FIG.

The various operation modes executed in this embodiment will be made clear by the explanation of program flowchart 1-, which will be described later, but an outline of the main operation modes will be explained here. .

(1) Normal readout mode This mode is a multi-menu set scale selection section 10 memory LED (Fig. 7) that is not lit or blinking, and the seven-point readout mode related to independent adjustment of pitch and volume for each note name phrase. The data to be initially set in the UPD memory 45 and VD memory 46 (FIG. 12) differs depending on whether the scale selection section 10 is enabled in response to the operation of the ON switch 16.

That is, in this mode, when the ON switch 16 is operated to turn off the 0N-LED (FIG. 7), the scale selection section 10 is disabled), the equal temperament memory 47 ( The data in Figure 12) is P

On the other hand, when the ON switch 16 is operated to turn on the 0N-LED, the scale selection section 10 is closed.
is enabled), the pure articulation scale or the preset scale displayed in the multi-menu window 14 can be selected, and the data corresponding to the lit scale LED is stored in the PD memory.

It is transferred to Sera 1 in the VD memory.

In this mode, regardless of whether the 0N-LED is off or on, data in the PD memory and VD memory can be uploaded and the town switches UP1 to UP12, DWNl-1)W
By operating N12 (can be changed freely).

(2) Hold mode This mode is used for Brisera 1 to memory 49-1 to 49-
24 (Figure 12) shows the scale data to be applied to Brisella 1.
This is a mode for creating pitch data and volume data for each note name, and is a preparatory mode for including preset and soto data.

By pressing the memory switch 17 (FIG. 7) only once, the hold mode is entered, and the memory LED (FIG. 7) flashes to notify that the hold mode is in effect.

In this mode, even if the rotary operator 15 and the scale switch SCL are operated, preset scale data or pure tone scale data is not set in the PD memory or VD memory. However, up and down switch U l)
1-UI)12. By operating DWN1 to DWN12, pitch data and volume data in the PD memory and VD memory can be freely changed. This mode is a preparatory mode in which scale data to be preset is created, so the player can perform the "UPD" by operating the up/down switch.
In order to prevent the data being created in the VD memory from being erased, the IC was designed to prevent the blaret scale data or pure tonal scale data from being stored in the VD memory.

In addition, in this mode, the register M R5(1) to

The old data is stored in the halt memory 50. The old data stored in the hold memory 50 is data that was created by asking the player J: during the hold mode or this prelet mode. Trying to write a set of pitch data and volume data for each note name created in the PD memory and VD memory to any preset memory (Prelet Shiny Tozuru)
In this case, it is preferable to be able to monitor the contents of the preset data currently stored in the preset memory and read the contents for confirmation. For such purposes,
Brisera 1 - Data read from memory to PD, VD

The data was saved from the D memory to the hold memory 50. PD. Once the data in the VD memory is stored in the hold memory 50, 1'' is set in the hold data register ILDCN to prevent the bold memory 50 from being rewritten any further. The four data that have been created are held in the hold memory 50. PD memory and VD memory are pre-certified by IEj where readout is performed.
It is possible to change the preset data as many times as you like, and it is also possible to view all the stored preset data.

Of course, even in Brisera 1-mode, the up and down switches UP1 to (]P12.To DWN1-DWN1
It is possible to change the contents of the PD memory and VD memory by two operations. However, the contents of the data once transferred to the hold memory 50 cannot be changed.

In this Blissera 1~ mode, by pressing the desired scale switch SCL and memory switch 17 at the same time, the created data will be stored in any of the Brillette memories 49-1 to 49-24 specified by this scale switch SCL. Brisera 1 to data are written from the halter mailer 50. This created preset data was saved in the bold memory 50, but if the PD
, If the data in the PD and VD memories has not been saved in the hold memory 50, the contents of the tangential hold memory 50, which has once transferred the data in the PD and VD memories to the hold memory 50, are occupied in the Brillet memory.

To cancel preset mode, press ON switch 16.
You can either turn ON/LED off by operating the average (1!) scale data to the PD or VD memory, or operate the rotary operator 15 to select the pure toning scale.

(/4.) -] Continuous mode Continuous mode is the up and down switch upi~
UP'12. When adjusting the pitch or volume for each note by operating DWNI to DWN12, the adjustment content currently being adjusted can be checked by continuing to emit a musical tone signal even if the key is not held down. J that can be monitored by hearing:
It was made by sea urchin. It is troublesome to operate the adjustment switches and the keyboard at the same time, but this continuous mode eliminates the need to keep pressing the keys.

Continuous Mode

Therefore, in the 1/- engine generator unit 26 (Fig. 11) which controls the sound generation according to this key A f4MKON <1) ~KON (8), the key continues to be pressed even though it is actually 1m11. The pronunciation continues as if it were. When a new key is pressed, the key-on signal KO corresponds to the actual A1 key.
N(1) to KON(8) are cleared to 0'', and the sounding of the musical tone signal of the key release performance that had been continuously sounding until then is erased.

Program Pleasure 11 Next, an example of a processing program executed by the microcomputer portion of FIG. 10 will be explained according to the sections 70-7-7 of FIG. 14 and subsequent figures.

Next continuous mode selection subroutine CON
The TSUB scans the continuous mode selection switch 11 and performs processing to determine whether to select the continuous mode in accordance with the operation. Details of this are shown in FIG.

The next keyboard subroutine KEYSUB scans each key switch on the keyboard and selects the 11th key switch. Based on the result of the sound recording, the ``pronunciation assignment processing'' and ``processing for continuous mode'' are performed. Details of this are shown in FIG.

In the next "Other panel controls scan" process, the other controls on the panel (tone selection section 1 in Figure 5) are scanned.
Scan the switches in sections 1 and 13, such as the tone selection switch and the master volume control,
Data corresponding to the scan results are stored in the panel data memory 57 (FIG. 13).

In the first and second steps of the main routine, l) D mail and VD memory (Fig. 12) and key code memory 5.

VD (1) ~VD (12), CI (1)-
CM(8), KON(1') to KON(8) are sent to the corresponding registers 28 to 32 in the tone generator section 26 (FIG. 11). Also, here, other display data that was not sent in each leave range in the previous step is sent from the memory or register in the data memory 20 to the display driver 22 (FIG. 10),
Each is displayed on a corresponding display. After the king, go back to the first board, Blue Jean, pvsuB, and repeat the main routine.

In the main routine, a display interoperable routine DISINT is loaded into an internal timer and periodically executed as an interlude 1 process. Here, processing is performed to blink the memory LED and the cool LED for a certain period of time. Details of this are shown in FIG.

(2) Pitch volume subroutine PVSUB No. 15
In the figure, it is first determined whether the contents of the I) V S E L register indicate the pitch (P) or the sound fl < V), and a routine for pitch adjustment or volume is executed depending on this size mi. Do any of the routines for adjustment.

In the pitch adjustment routine, first, pitch name-by-pitch big adjustment processing 58-1 is executed for pitch name C.

In this process 58-1, it is first checked whether the up switch UPI related to pitch name C is turned on, and if it is turned on, the pitch data PD(1) of pitch name C in the PD memory is
Check whether the value is the maximum value "55". If the maximum value r 55 J has not yet been reached, it means that there is a possibility that PD (1) can be further increased, so the predetermined change width data ΔP is added to PD (1) and the sum is Check whether the maximum value exceeds 55 J (PD(1)→-△p>r55j?). If you don't exceed
This means that the increase is still possible, so in block 59, △P is added to PD(1), and the sum is stored in the PD memory as a new PD(1) (PD ('l
)←PD(1)-1-△P). Then, the value of this new IC PD(1) is displayed on the corresponding liquid crystal display LCDI. On the other hand, if PI)(111-ΔP exceeds "55", the value of PD(1) in the PD memory is set to the maximum value "55.0" from the process 1 of block 60. is displayed on the display L CD 1.

In this embodiment, when the up switches UP1 to UP12 are pressed, the predetermined big change width data △P (in the case of volume, the volume change width data △V) is changed to 1 every time this subroutine PVSUB is executed. By repeating 1-J, PD(1) to PD(12) (in the case of a sound field, VD(1
) ~ VD(12)) and down switch [)WN
1 to DWN If 12 is pressed, the change width data ΔP.

△■ is set to 1 each time subroutine PVSUB is executed.
PD (1) to PD (12) or VD (1 block□ to VD <12) is decreased by reducing the number of times. Here, △P should be preset to an arbitrary value with the minimum unit being ro, IJ (corresponding to 0.1 cent).
(However, depending on how this ΔP is set, the value of the pitch data may not be exactly the maximum value r55.OJ.

For example, ΔP is ro, 4. In case of J, pitch data PD
When the value of (1) to PD (12) is r5/1.8'J, if you add this △P, the sum becomes r55.2J, and r5
5. Do more than O.J. In such a case, the values of pitch data PD(1) to PD(12) may be set to a maximum of 1ifJr5.
5. The process of block 60 is performed to limit OJ. Similar processing is performed in block 61 for pupil reduction. Also, in the case of volume, the minimum unit of △V is "1"
can be predetermined to an arbitrary value, a similar problem arises, and a maximum or minimum value limiting process similar to that described above is performed in blocks 62 and 63.

After the processing of block 59 or 60 or "UP1A?"
” is NO or lPD (1) = r55J? J is YE
When S, check whether the switch DWN1 is turned on. Then, the minimum till r
-About 55J? The same judgment as in the case of the knob switch U[)1 is made (however, whether or not it can be reduced is determined by PD(1)-
△P<r-55J? Judging by) 1, PD (1)
If it is possible to still reduce ΔP, then in the process of block 64, J: is used to reduce △P from PD(1) and write it in the PD memory as a new PD(1), and display this on the display LCD1. Display in . On the other hand, if PD(1) cannot be reduced anymore, block 61 says J: and PD
The value of (1) is limited to the minimum value r-55, OJ.

Thereafter, the pitch adjustment process for pitch name C and processes 58-2 to 58-12 similar to 58-1 are performed for each of the remaining note names □b to B, respectively. However, in each process 58-2 to 58-12, the switches UP2 to UPI 2. D.W.
Check N2-DWN12 and adjust pitch data PD(2) to PD(12) corresponding to the pitch name.

On the other hand, in the routine for adjusting the volume, first, an adjustment process 65-1 for each pitch name C is executed. First, the process related to up switch U f) 1 is pitch adjustment process 5.
This is the same as in case 8-1, and the adjustment target is the volume data VD<1) corresponding to note name C in the VD memory,
The change width data is △V and the maximum value is rlooJ
(decimal number) is different from the case of bidge adjustment. Next, down switch DWN 1
This is a process related to rDWN 1 , dn?
” is the height of NO and rVD (1) = rOJ? The process is the same as the pitch adjustment process 58-1 except for the process when J is YES, except that the adjustment target is the volume data VD(1) in the VD menu, and the minimum value is rOJ.
(decimal number) and the change width data is △■, and the down flag DWNI is different.
A step 66 is provided in which the down flag DWNFLG is set to rDWN.
1 on? J YES I'VD (1) == rOJ

) WNFLG is reset to 1'' and checked to see if it is 0; if it is, the block 67 is sent to -3 and it is reset to O''.

rVD (1) = rOJ? When J is YES, da
It is checked whether the thin flag DWNFLG is set to 1 (block 68), and if YES, this process 65-1 is ended, but if it is NO, the process proceeds to block 69, and "off display" and "clear display" are performed. Perform processing for.

rVD (1>= rOJ? If J is YES, it means that the volume data VD (1) has been adjusted to the sound atmosphere. At this time, block 68 is YES. E'S means that the down switch DWN1 is pressed. This means that the volume is adjusted to zero and the switch is continued to be pressed.In such a case, the volume simply becomes zero, and [A) Display j and "Reference display" are not performed. . Therefore, if the up switch UP1 is pressed next time, the volume data VD,(1) can be increased again, but the corresponding note name is not disabled.

On the other hand, if block 68 is NO, the volume data VD(1)
This means that after the volume was adjusted to zero, the down switch DWN1 was turned off and then pressed again.

In other words, is rDWN1 on? J's No. J: Reflag D

The characters "FF", that is, the volume "off display" are displayed on the display device LCDI. However, later, P/VSEL
Switch to pitch adjustment mode by operating the switch 4)
When it is, the display L Cl) 1 indicates that P is cleared.
Based on D(1), "clear display" (that is, nothing is displayed) is performed. Although no particular program is shown,
PVSEI - PD memory and VD depending on register contents
One of the data stored in the memory is displayed in each mLco1 to L.
Of course, the process for displaying on the CD 12 is executed somewhere in the main routine (for example, in the last data sending process of the main routine). This "off display" and "clear display" can be done by pressing the up switch UP.
1~UP12 or down switch DWN 1~DWl1
12, the C cannot be resolved, and the equal temperament data is rewritten by the data set from 1 to 1 when the pure key data or Brisella 1 data is written to the PD memory or VD memory. Furthermore, "off display" and "clear display" can be included in the preset data and written in the preset memory. When creating a desired scale, if you set "off display" and "clear display" for a specific note name, you can delete that note name from the scale.

Below, note name C sound 1mtJ adjustment 1!1'! Processes 65-2 to 65-12 similar to 65-1 are executed for other pitch names ~B, respectively. In that case, switch UP2 to UPI corresponding to that note name 2. DWN2 to DWN12 are checked and the volume data VD (
2) to VD (12) are adjusted.

In this embodiment, the pitch poly:LLx leave routines PVS, UB are not performed every time in each recycle of the main routine, but are performed once every few cycles. The rate is 1) selected by the 0L rate selection switch (FAST/SL-OW> in Figure 6).If the high speed (FAST) is selected, it is selected once every relatively few cycles. p v su
s is executed, and therefore the interval at which ΔP and ΔV are added or subtracted becomes faster, and the speed of data change during pitch or volume adjustment becomes faster. When the low speed (S'LOW) is selected, PVSUB is executed once in a relatively large number of cycles, and the ΔP, Δ■ addition/subtraction evaluation interval becomes slow, and the data change speed becomes slow. Therefore, there is no need to change the values of the change width data ΔP and Δ■ regardless of whether the speed is high or low.

However, the invention is not limited to this, and the n1 frame interval is constant, △P,
(3) ON switch subroutine 0NSUB In Figure 16, the ON switch 16 is checked first, and if it is A, it returns, but if it is on, it returns. Invert the storage signal of the multi-on register MLTON to 1'' or II OT+. Next, M
Check whether the contents of the LTON register are O''. YE
S means that the multi-menu set scale is selected and function 10 is not enabled, so 0N-LED
, turn off all the scale LEDs, lower the volume of all notes being sounded (all-tone level down), read out the stored data of Well-Tempered Meri 47, and save it to the PD memory and VD memory. Equal temperament mode (hereinafter all blocks marked 1'F'D, VD mode and equal temperament set' have this meaning), and then re-sound processing (cancels the volume level down and returns to normal mode). data reflex 1 to PD memory and VD memory
~The "whole-tone level down" and "re-sounding" processes that are executed immediately before and after are caused by the sudden change in the volume and pitch of the sound being played by rewriting the data stored in the PD memory. This is achieved by lowering the volume level before data exchange and returning to the original volume after data exchange. 61] [) Memory in other routines.

This process is inserted when the data bar 1 of the VD memory is replaced, but its explanation will be omitted hereafter.

On the other hand, when the signal of the MLT'ON register is 1'', it means that the multi-menu set scale selection section 10 is enabled, so the ON-LED is
, and one scale LED corresponding to 5ELECT (ROI-△RY) is lit. 5ELECT (RO
TARY),! : is any one register 5ELECT(
1) to 5EI-ECI-(3), means the number of the scale switch SCL stored in C. This display shown in other routines all have the same meaning. Next, in block 78, the rotary switch position (any one of 1 to 3) stored in the ROTARY register and one register 5ELECT (1) to S1 LECT (3) corresponding to this rotary switch position are input. The stored scale switch number, that is, 5ELE mentioned above.
In combination with CT (ROTARY), genuine adjustment memory 48-1 to 48-12 or preset memory 49-
A set of pitch data and volume data is read out from this memory and set in the PD memory and VD memory, respectively.

Hereinafter, it will be written as [read out the selected genuine tone or preset memory and store it in the PD and VD memories], and the lζ block means a lever.

(4) Memory switch subroutine MEMSUB No. 17
In the figure, first the memory enable register MEMEN is set to 1.
”, and if YES, this subroutine will not be executed. If NO, check if the memory switch 17 is on, and if it is, l-10
Check whether the signal of the LD register is OII. If the memory switch 17 is suppressed for the first time, N OL
The D register is still OII and rNOLD="O
” The iJ<-old mode process 70 is executed via the JYES route.

In the hold mode processing 70, the contents of the MLTON register are 1'' and the contents of the ROTARY register do not indicate rotary switch position 1 (genuine tone selection), that is, the multi-menu set school is selected and the function 10 is selected.
On the condition that the preset memory can be selected in block 71, the scale and ED corresponding to the stored preset memory are displayed. That is, in block 71, registers MR3(1)-(12) or MR3(13)-(
24) and lights up scales L and ED in accordance with the stored contents. Register MR3 (1) to (12
), MR8, (13) to (24) have already stored the signal II I 11 corresponding to the recorded pret memory g:i, so the scale L corresponding to the stored pret cell 1-memory is stored. ED is lit. Note that it is not possible to light up the scale LEDs for all 24 preset memories, but for the ROTARY
This is done for 12 prehit memories corresponding to either rotary switch position 2 or 3 stored in the register. As for the remaining 12 Brisella 1 ~ memories,
By changing the rotary switch position, school LED lighting processing is performed by processing 74 of subroutine ROTSUB in FIG. 18, which will be described later.

Finally, in the hold mode processing 70, "1" is set to the HOLD register to clarify that the bold mode has been entered.When the hold mode is set in this way, the display interface 1 shown in FIG. ~ In subroutine DISINT, rl-10LD = “O”
? J is determined to be No, and processing to blink the memory LED is performed. The player confirms that the memory LED is blinking to confirm that the player is in bold mode, and then checks the lit scale LED to determine which memory has been stored, from Priscella 1 to memory (on the contrary, if there is an empty Priscella 1 to memory). ) can be confirmed.

On the other hand, if the memory switch 17 is pressed again after entering the hold mode, 1-1 "0LD-" in FIG.
O"?J becomes NO, and Bricella 1-mode processing 72 is executed. Here, the stored contents of the ROT II Y register are at rotary switch position 2 or 3 (that is, Bricella memory is selected). , and MLTON
On the condition that the register is 1'', the signal “°1” is sent to the memory enable register MEMEN from Sera 1 to 80.
1 Set the D register to ``0°'' to Relen I, and set MR3 (1
) to (12) or the school LED that was lit based on the contents of MR3 (13) to (24). 1~Move to mode.

On the other hand, in the hold mode, when the content stored in the ROT ARY register is at rotary switch position 1 (that is, genuine tuning is selected) or when the Ml-ON register is at "O", the memory switch 17 is When pressed, the process proceeds to block 73, where the l-1OL+) register is reset to 0'°, the memory LED is turned off, and the hold and hold state is released.

(5) Rotary switch R8W output and R
Compare the contents of the OT ARY register to see if they are the same or different. If they are different, the output of rotary switch R8W is transferred to the Ro1ΔRY register. The contents of the ROTARY register thus indicate the currently selected rotary switch position. Next, check whether the signal of the MLTON register is O'' or not, and
In other words, if the mode selects genuine tone or Bricella 1-memory, proceed to the next step and check whether the signal in the NOLD register is 1''.HOL I) If "1" is set in the register Hold mode processing 74 is executed. Here, it is checked whether the contents of the ROT△RY register are rotary switch position 1 (genuine tone), and if NO, that is, the memory is selected for preen 1 of rotary switch position 2 or 3. If so, perform the processing in block 75.The processing in block 75 is the same as the processing in block 71 in FIG.
is the same as

In this way, by switching the rotary switch R8W to position 2 or 3 during the hold mode, the memory 49-1 to 49-1 of the memory 49-1 to 49-1 can correspond to the hold state.
2 or 49-12 to 49-240) Among them, the scale LED corresponding to the scale 9i completed is lit.

When in a mode other than hold mode, that is, normal read mode or preset mode, r l-10L D-P1
′′? ” is NO, then 11 L at block 76
[) Check whether the signal of the CN G register is ``1''. If NO, then check whether the MEMEN register is ``1'', and if MEMEN is 1'', this subroutine ROTSU [I'm finishing 3, but l
-I L D CN G is 1" or MEMEN is "0"
If so, after performing the "whole tone level down" process, the process of block 77 is performed. Block 77 is the same process as block 78 in FIG. 16, and includes the storage contents of the ROT ATY register and any one of the corresponding scale number registers 5ELEC,T(1) to 5ELEC,T(3).
That is, data is read from the genuine tone or preset memory in accordance with the combination with the scale number stored in 5ELECT (ROTARY) and set in the PD and VD memories. After that, perform the “re-sounding” process and select 5ELECT (R
OTARY) lights up the scale LED.

The 1-ILD CN G register is set to the signal II i 11 when the data in the PD memory and VD memory is shifted to the bold memory 50 at the time of preset upper mode, and the MEMEN register
- mode, the signal is set to "1". Therefore, in the preset mode, the PD memory, VD
If the data in the memory has not yet been shifted to the hold memory 50, the process at block 77 is not performed and M
From YES of EMEN=“1” to “return”. On the other hand, if the data in the PD memory and VD memory has already been shifted to the hold memory 50 in the preset mode, the process passes through YES in block 76 and proceeds to the process in block 77. This rotary switch ROTS
Passing through YES in block 7G of UB is to store the data of the D memory and VD memory in the bold memory 50, and then press the rotary operator 15 to override the selection of which preset memory this data is to be allocated to. This is the case when you manipulate the . In addition, in the normal read mode, M
The process goes through the NO rule 1- where EME N = "1" and reaches the process of block 77.

This rotary switch routine r< o 1-s
u In B, the position of the rotary operator 15 is changed, but the processing in block 77 is performed in P, and a specific scale number is specified without any particular operation of the scale switch SCL, and the selected scale number is selected as the scale number in A. Depending on the combination with the selected rotary switch position, pure tonic scale data or prelet data is stored in the PI) or VD memory. This is the scale that corresponds to each rotary switch position. Number register 5ELEC
T(1) to 5ELECT(3) correspond to the last operated scale switch S corresponding to each rotary switch position
This is because the number of Cl- is stored. in this way,
〇-Although the combination of the tally operator 15 and the scale switch 5CI- allows selection of Precera 1~memory or genuine tone memory, it is not necessarily necessary to operate both at the same time; 15 as appropriate (you can also make selections using the buttons, so the operation is easy.

(6) Scale switch the Brugen CLSUB In Figure 19, first the MLTON register is set to the signal 111.
Check whether it is set to II, and if YES, check whether the HOLD register is 0''.

If 10 L D = "O" is No, that is, in hold mode, return and this subroutine 5
CLSUB will no longer be executed. Therefore, in the hold mode, the scale switch operation is disabled even though the MLTON register's '1' t? Shift J: Rescale selection U function 10 is enabled. The data for BURI Utsu 1- that is being created in the PD, VL memory is stored in the PD, Vl) memory so that the data for the This is to prevent data that should be preset from being destroyed.

If not in hold mode, scale switch S CL
Check to see if any of them are activated, and if YES, compare 5ELE, CT (ROTARY) and the number of the school switch SCL that was turned on. In other words, R.O.
Any one scale number register SE, LECT (1) to S, 'EL, E C1'' corresponding to the rotary switch position stored in the T A RY register.
(3) Compare the scale number stored in C with the number of the scale switch SCL that was turned on this time. If they match, the same scale switch SCL is pressed and t=
<or means that the button continues to be pressed, so the process goes to ``Return'' without executing subroutine 5CLSIJB. On the other hand, if there is a mismatch, the number of the scale switch SCL that was turned on this time is read as the stored data 5ELEC (ROTARY) in the scale number register corresponding to the current rotary switch position. Next, the number of the scale switch SCL that was turned on this time is read. Turn on the scale IED. Then rlVIMEN=
'“1”? J is checked, and if it is No, it means the normal read mode, so the process jumps to the "whole tone level down" process, and the process in block 79, which is the same as block 7B in FIG. 16, is executed. In this way, in the normal read mode, data is read from the genuine tone or Bricella 1-memory selected according to the operation of the school switch SCL, and written to the PD memory and VD memory.

On the other hand, in the case of Brisera 1 ~ mode, rMEMEN= r
r 1 ” 7 J is YES and I' HL D
CN G =゛1''?J is checked. If the data in the PD and VD memories has not yet been shifted (saved) to the hold memory 50, (LDCNG is 0'', and the processing in blocks 80 and 81 is performed. In block 80, HL
Set DCNG to 1″, set Sera 1-shi, PD in block 81,
The data in the VD memory is let (evacuated) to the hold memory 50. Thereafter, the process of block 79 is performed, and the selected brissera 1 data is transferred to the PD and VD memories. Once the processing of block 80.81 is performed, the next 1 no-routine S CL S (J [1LDcNG = "1" in J[3?] is YES, and block 80.81 is jumped to block 79. Therefore, In the preset mode, when the first scale switch SC is pressed, the data in the memory (PD, Vt) is stored in the hold memory 50, and from then on, no matter how many times the school switch SC is pressed, the PD, VD Only the data in the memory is rewritten, and the data that was once saved in the hall monograph 50 (the data that should be preset created by operating the 7-up down switch) is not changed. The data to be stored is stored in the hold memory 50, and on the other hand, the stored data in each preset I-memory is read out to the PD and VD memories as many times as necessary to monitor and store the contents. While checking the contents of the already created preset data, you can check which preset memory to write the newly created preset data into.

(7) Bricera 1 ~ Data writing subroutine P S
T S IJ B In Figure 20, first the MEMEN register is II OII
If it is YES, it means that the mode is not Burilev 1-mode, and the process goes to "return". No, that means MF M E
If N = “1”, then memory switch 1
7 and any school switch 5CI- are turned on at the same time, and if NO, this subroutine P S
T S U B is not executed any further, but if YES, this subroutine is further executed and the preset memory 1 data is written to the preset memory.

First, set the MEM register to 1'' to clearly indicate that the preset data has been written.Next, set the memory timer register MEM (lower IM) to a predetermined initial value (this is the time when the memory LED should blink). Next, write the rotary switch position stored in the ROTΔRY register and the scale switch SCLσ that is currently turned on.
) In combination with the scale number, specify the preset memory to which the data is to be written, and read the addresses of the brissera 1 to memo 1. Next, in the memox 11 nub routine, the address cell 1 set in the previous step is
Write the data to be stored in the hold memory 50, PD memory, or VD memory 1 to the PriRef 1 memory.

Details of the memory save routine are shown in FIG. Here, 1 is added to the l-I L D CN G register.

If CNG is O'', PD, V
Indicates that the data created in the D memory has not yet been saved to the hold memory 50, and in this case, the data from the PD and VD memory is temporarily transferred to the hold memory 50 in the process of block 83. After that, the processing in block 82 is performed to enter predetermined presellers 1 to 4. In this case, instead of the process in block 83, the data in the PD and VD memories may be written directly into one preset memory of the address cells 1 to 1. Finally, the registers MR8 (1) to (12), Mn2 (i3
) ~ (24), connect the signal 111 I+ to the position] ~,
It clearly states that the Brillet memory has been memorized.

Returning to Fig. 20, after the memory save routine, all scale LEDs are turned off, the whole tone level is lowered, and the data in the preset memory that has just been written is read out, and the data is read out from the PD memory and VD memory. , respectively, and the contents of the data can be confirmed to Priscella 1, which has just finished writing the command. After that, l-I L
Set the D CNG register to "o".

(8) Brisera 1-mode release 1 knob routine P[ED
SUI3 In Fig. 22, first check whether the MEMEN register is 0'' or not. If NO, it is in Bricht mode, so proceed to the next step. Next, check if MLTON is ``O'' or not.
The content is the rotary switch! Check whether it is 61. The ML T ON register is set to ``O'' by operating the ON switch 16.
When 11 is reset to 1~ (as shown in Fig. 16, when the average 11! is set to 1~), or by operating the tarry operator 15, the genuine tune (rotary switch value 1) is set. Selected! At this time, turn off the memory LrED and reset the memory enable register MEMEN to 0''.
This will cancel Bullet Mode. lastly,

The EMTIM register is shown in Figure 20.
When StJB is executed, a predetermined initial value is set to 1, and this initial value is decreased by 1 to fO when this ink club tree DISINT is performed once. Note that when the contents of the MEMTIM register become "0", no further subtraction is performed in the "timer processing", and "0" is maintained.

When the preref 1 data is written in the Brillet mode as described above, the MEM register is set to "1" (Fig. 20, section 1!, IIVIEM-"o"
;' is NO, and it is checked whether the contents of the MEM-r1M register have become rOJ. If it is still "0", the process of subtracting points from the scale LED corresponding to the PRILEF 1 memory is performed. In this way, the scale LED blinks until the predetermined blinking time set for the initial cell 1 has elapsed in the MEMTIM register. The content of MEM King IM register is “0”
When this happens, the MEM register is reset to 0'' and the scale LED stops blinking.

If it is 11+, the continuous LED (which is provided on the panel corresponding to the continuous mode selection switch) is turned on, and if it is II OII, the continuous LED is turned off. (1) Whether the continuous mode is selected or not can be determined by blinking or extinguishing the continuous LED.

(11) Kehoe 1-”) Frutine KE YS
UB In FIG. 25, at block 84! ! Each 4-switch on the board is scanned, and the key codes of all suppressed keys are stored in the new key code memory 55 (FIG. 13) as new keys. Next, in block 85, the volume data VD (1') to V for each note name stored in the VD memory (Fig. 12) is

Delete from. The process of block 85 prohibits keys corresponding to pitch names adjusted to zero tone or "off display" (off display is also included in volume zero in a broad sense) from being assigned to the musical tone generation chitunnel.

Next, at block 86, the A-old key code K FEYOLD stored in the A-old key code memory is
(The key code of the key detected in the previous scan recycle key press) and the new key code KEYNEW are compared, and if they all match and there is -C, there is no need to perform new assignment or key word processing. This subroutine KEY
The SUB is terminated, but if there is any phase 3fUJ even in part, the process proceeds to block 87. In block 87, the key code changes from key off to key off based on the comparison result of block 86.
Or the key code of the key that changed from key-off to key-off (not included in KEYOLD)

9 (1) After executing the sound generation stop processing 90 at YIF S note/L/-, the sound generation channel assignment processing 91 is executed. If it is not the continuous mode, the process moves on to the sounding channel I7 channel assignment process 91 one after another in the No. 1- of the block 8. Pronunciation channel assignment process 91
Now, the key-on signals KON (1) to KON (8) of each tunnel in the key-off memory 52 (FIG. 13)
(Check D4m, pick up one of the tunnels whose value is 'O' (that is, key A) as a newly assigned tunnel Y, and press the key-on corresponding to the tunnel Y in the key-off memory 52 and true key-on memory 53. Signal K

After that, in block 92, it is checked whether processing has been completed for all the change key codes NKC stored in the change key code memory 56, and if No, the process returns to block 88.
The same processing as described above is performed for another unprocessed) change 1-:1-do NKC.

The platform for which the change key code NKC has been newly keyed A- goes to block 93 from No in block 88 to check whether it is in the continuous mode. If it is a continuous mode, the process proceeds to block 95; otherwise, block 94 is executed and then block 95 is executed.

In block 94, the change key code NKC currently being processed is
And each chi 1? Key code CI assigned to the channel
(1) to C1-1(8) are compared, a channel X with which both match is detected, and the key-on signal KON (X) in the key-on memory 52 corresponding to that channel
Add Reren 1- to I+. In block 95,
4, change key code NKC and each key code C1-
Compare 1(1) to C1-1(8) and find that they match.
Channel X is detected, and the key-on signal king KON (X
) to "o". In the case of continuous mode, block 94 is not executed, so even if the key is turned off, the key-on signal KON in the key-on memory 52 remains
(1) to KON(8) are not reset to 1'' and are maintained at 1'', so that they are processed as if the key press continues. In other words, as shown in the front), each of the channels connected to the i--engenerator section 26! This is because the sounding of the channel is controlled based on the key-on signals KON(1) to KON(8) of the key-on memory 52 rather than the true key-on memory 53.

When a new key-on is detected in the continuous mode, a sound generation stop process 90 is executed. Here,
First, the channel number 1j is set to 1, and then, in block 96, the true key-on signal TKON (K) and key-on signal KON (K) of the channel corresponding to this number 1 are input to each key-on menu. From Shisu 52 + 53, each read 21 and rKON (K) is 0'', so KON (K)
Check whether is '1'' (in other words, it is actually -1-A)
Check whether the sound is controlled as key-on even though the If Y E S <r, set the key-on signal KON (K) to 'O'' and stop the sound. Next, increase the key-on signal KON (K) by 1 and block it. Returning to step 96, the above-described processing is repeated, and when the number of shifts exceeds the total number of blocks and channels and reaches [9], this sound generation stop processing 90 is terminated.

In this C1 continuous mode, the musical note that is released is actually pronounced as if the key had been kept pressed, but when a new key is pressed, All of these key release sounds are treated as key-offs, both in name and in reality, and the sound generation is stopped.

Note that in order to prohibit the assignment of keys corresponding to pitch names set to Onmura Zero or "off display", processing is performed at block 85 in FIG. 25, but the process is not limited to this, for example, block Even if the assignment for this note name is prohibited during the assignment process in block 91, or the change key code NKC will not be detected for this note name when detecting the change key code NKC in block 87. You can do it like this.

In the above example, we have explained the control of the note m, but the same applies when adjusting other musical sound elements (for example, timbre, modulation effect, etc.) independently for each note name. It can be carried out.

Furthermore, the configuration of the adjustment operator and the display device may be any type, for example, it is not limited to a pushbutton switch, but may also be a latch type switch, a full die A type operator, or other types, or a display device may be used. Independent from the controller
Any other modifications, such as changes to the scale plate of the operator, are within the scope of the present invention. Similarly, the operator for selecting the button is not limited to the one in the embodiment, and any operator may be used. Memory is also 21/j to Brisera 1! It is limited to physical memory, and may be mechanical memory including switches, levers, etc., or may be external memory such as a magnetic card.

The tone generator section 26 of FIG. 11 accumulates the frequency numbers at the 1st clock after setting the musical tone frequency (
For pitch control I, this frequency number is changed, but the method is not limited to this, and the musical tone frequency can be set and pitch controlled using any method, such as a variable frequency division method or an independent oscillation method for each note name. The present invention can also be applied to devices designed to perform. Further, the present invention can be applied not only to digital electronic musical instruments but also to analog electronic musical instruments.

In the above-mentioned embodiment, the operation of each switch and the storage process are performed by fair processing in the software 1 of the microcomputer, but it may also be constructed using a hard-wired circuit that performs the same functions. On the other hand, in the embodiment described above, the hard soy 1 hood circuit performs the operation for changing the frequency number from 1 to 1 in accordance with the pitch data, but it can also be performed by rough l-ware processing.

Note that the configuration related to the Priscella 1 to 1 function shown in the above embodiment is not limited to the Pricella function (scale Brisella) for controlling musical tone elements for each pitch name as in the present invention.
It can also be applied to commonly known bullet functions such as tone, volume, and modulation effects.

One characteristic technical idea that can be extracted from the Brisera 1-Tsukiyoshi shown in the example is that in which combination of the rotary operator 15 and the school switch SCL, the Brisera 1-LC data is much larger than the number of operators or switches. It is possible to select and override the set.

Such a multi-menu set Brille 1 - selection operation is as follows:
This invention is not limited to the selection of scale pre-ref 1-data, but is also applicable to the selection of pre-ref 1-data such as tone selection operators or volume adjustment operators common to all known note names. You can do it. In recent electronic musical instruments, there are quite a large number of selectable preref 1 data sets, and each preset data phase has an individual selection switch. This would result in an increase in strike price and the problem of placement space.

Therefore, in a broad sense, the combination of a rotary operator and a scale switch as shown in this embodiment is a method that divides a large number of selectable prelet data sets into multiple groups () and allows selection of individual groups. A combination of a first switch means and a second switch means for selecting individual presellers 1 to data sets within one group, and a multi-menu display means belonging to a rotary operator. (Means for providing an identification display of selectable Brilet data sets within the group selected by the first switch means) can also be applied to the Brilet I-device 6, such as a normal tone or volume or effect, at a cost. In addition, the number of switches is reduced, which improves operability.

Another characteristic technical idea that can be extracted from the Brisera 1 function shown in the embodiment is that a hold mode is provided as a preparation means for the Preref 1 mode, and it is possible to determine which Brisera 1 memory is currently in use and has been stored. In this hold mode, it displays which preset memory is free or can be used without destroying the data from preset 1 that has already been memorized. - It is convenient for data creation and writing work). Also, during this hold mode, the data in the prelet memory is not read out to the pitch data memory and the volume data memory, and the prelet river data (prelet river data) being created in the pitch data memory and volume data memory is stored in the pitch data memory and volume data memory. - The data to be written to any preset memory as data) is not destroyed, and the user can concentrate on creating data for the pre-recorded version 1. This J: Una Bold mode can be applied to normal tone, current fl- or effects, etc., to Brillette 1 to Device j/f, and the Brillette function can be improved.

Yet another characteristic technical idea that can be extracted from the pre-en l-1m function of the embodiment is that the hold memory 50 is provided and the pre-created brisef l is stored in the pitch data memory and @quantity data memory.
- data can be saved to this hold memory, and once the data is saved, the data in the hold memory will not be rewritten and the created data for Brisera 1~ will be held; Preref 1
-The data was monitored many times.

These other techniques can also be applied to one-piece equipment, and can improve pre-reflex functions.

As described above, according to the present invention, the volume or pitch or any other musical sound element can be adjusted independently for each note name, which is extremely useful in music education or pitch education. It can be applied advantageously and can bring about various musical effects not only in normal performance but also in normal performance.Furthermore, according to the present invention, a new scale presera [-1 function is provided. Therefore, the performance performance of electronic musical instruments can be improved.
