Description

Description: (a) Field of Industrial Application The present invention relates to an electronic musical instrument having a plurality of musical tone output sections such as a stereo, which can freely set a sense of localization of a musical tone to be generated.

(B) Conventional Technology A general electronic musical instrument has a stereo output section for producing generated musical tones on the left and right channels, and by adjusting the left and right output levels, the musical tone can be localized. . Some electronic musical instruments can produce multiple tones at the same time, and if multiple tones are pronounced in the same localization, the sound is not wide enough.Therefore, it has been proposed to shift the localization of each tone. (Japanese Patent Laid-Open No. 55-
121492). As a result, a different sense of localization is obtained for each timbre, so that when a plurality of timbres are simultaneously pronounced, a sound field like an ensemble can be formed. In addition,
In "Effect device for electronic musical instrument" shown in 62-18349, a proposal is made to move a musical sound localization during a performance.

(C) Problem to be Solved by the Invention However, in the above-described “effect device for an electronic musical instrument”, sound image localization control is performed for each timbre, and therefore, in the case of producing only one timbre of musical sound. There was a risk that the sound would become monotonous. In addition, since the configuration is such that only the movement control (pan control) of the sound image is performed using an operator such as a wheel, there is a disadvantage that complicated pan control cannot be performed.

In view of such a situation, the present invention makes it possible to perform a complicated pan control even in the case of producing only one tone of musical sound, and also to perform different pan control depending on a performance operation or an auxiliary operation. It is an object of the present invention to provide an electronic musical instrument capable of performing.

Sub-control means (RT, n43 (n80 to n85)) for setting output level ratios for the plurality of musical sound output sections based on parameters (modulation wheel, cursor key, jog dial output) generated with the main control Means for storing the maximum control range of the means and sub-depth for the maximum control range of the sub-control means. In-depth storage means (SCD
(M)) and a sub-depth storage means (BD (m)) are provided, and the output levels of the plurality of waveform elements with respect to the plurality of tone output sections are set to the set value (VL) of the main control means to the main depth. Value (n45, n46) multiplied by and the set value (RT) of the sub-control means multiplied by the sub-depth (n82, n85) composite value (SF / PNB (n),

In a fourth invention of this application, in the second or third invention, the main control means and the sub-control means select arbitrary parameters from a plurality of parameters (VKL (m), COLR ( m)), the output level ratio is set based on the selected parameter.

(E) Action of the Invention In the first invention of this application, the sound image localization is performed for each waveform element by adjusting the output level ratios for the plurality of tone output sections for each of the plurality of waveform elements forming the musical sound. Pan control can be performed. This makes it possible to perform complicated pan control even when a musical tone of one tone color is produced.

Is performed corresponding to the combined value with the control value (sub-control means) based on the auxiliary operation (modulation wheel) of. As a result, it is possible to perform pan control with rich expressiveness in response to the performance operation state of the performer.

Further, in the third invention of this application, in the above pan control, the maximum control range by the main control means and the sub control means is set by the main depth of the main depth storage means and the sub depth of the sub depth storage means.

The sound source device 18 is connected with two sound systems 20, 21 on the left and right sides, and can output the tone signals separately synthesized on the left and right sides. The sound systems 20 and 21 correspond to the musical sound output section of the present invention.

3 and 4 show register areas set in the RAM 13.

FIG. 3 is a list of registers in a voice data storage area for storing tone color (voice) data that can be produced by the electronic musical instrument. This electronic keyboard instrument stores a lot of tone color data (about 64 tone colors), of which 8 tone colors (m = 0 to 0)
7) can be set in this storage area as a tone color capable of simultaneous sound generation. Each tone has 4 elements (waveform element: n
= 0 to 3). Each register is set for each voice (m) or each element (m, n).

The static pan data SPAN (m) is data representing a pan position in static pan control. The data range is -50 to +50. When 1 is set to 50, this musical sound is localized to the left channel position, and when +50 is set to the right channel position. When a value between them is set, it is localized at the intermediate position corresponding to that value. That is, the balance causes the left and right channels to produce musical tones. When -51 is set, dynamic pan is performed.

The depth control flag AM (m) and the controller assign flag COLR (m) are flags for designating a sub controller in dynamic pan.
When AM (m) is set, the built-in LFO becomes a sub-controller, and when AM (m) is reset, the operator specified by COLR (m) becomes a sub-controller. When COLR (m) is 0/1/2, cursor key 2c,
The modulation wheel 2e and jog dial 2d are sub-controllers.

LFO depth data LD (m) is LFO to sub-controller
When is specified, it is the data that specifies the control strength of the LFO.

The bias depth data BD (m) is data that specifies the control strength by the manipulator when the manipulator is specified by the controller.

The source assign flag VKL (m) is a flag that specifies the main controller of the dynamic pan. This flag is a 0/1/2 three-state flag. When “0”, the key touch strength of the key that specified this tone becomes the main controller, and when it is “1”, the key number of the key that specified this tone, When set to "2", LF provided elsewhere
O becomes the main controller.

The LFO constant CONST (m, n) is a constant for setting the angular frequency of the LFO when the LFO is designated as the main controller.

The source depth data SCD (m) is data for setting the control strength of the main controller.

The select flag SN (m, n) is a flag that stores whether or not this element is selected to sound. When this flag is set, if the voice m is specified, this element will sound, and when it is reset, no sound will be generated even if the voice m is specified.

A storage area for parameters (EG pan data) for calculating EG pan is also set in this storage area.

As EG pan data, direc-time DT (m, n),
Key-on pan rates 1-4, key-off pan rates 1,2 (PR
(S) (m, n): s = 1 to 6), key-on pan level 0
4, key-off pan level 1, 2 (PL (s) (m, n): s = 0
6) and the loop point LOOP (m, n) are stored. A pan envelope as shown in FIG. 6 is calculated from these data. That is, the sound image sequentially moves through the key-on pan levels 0 to 4 during the key-on, and the rate of change during the movement is designated by the key-on pan rates 1 to 4. When key-on pan level 4 is reached, if key-on is still in progress, LO
This envelope is repeated again from the key-on-pan level position specified by OP. After the key is turned off, the sound image position is controlled by the key-off pan level 1 and 2 and the key-off pan rate 1 and 2 until the musical sound is completely muted. Even in this case, the key-off pan level 1 and 2 are repeatedly traced until the sound is muted. The delay time is a delay time from the start of panning from the key-on pan level 0 to the key-on pan level 1.

In addition to these data, the voice data storage area stores a tone color data group that determines the musical tone waveform of each element and an EG data group that determines the tone generation level.

FIGS. 4A to 4D show a register group other than voice data.

FIG. 3A shows a key event buffer. When the key is turned on or off, the contents are stored in this buffer.
The stored contents are key on / key off, key number and key touch. In the case of normal key on / off, the content is stored in the area of N = 0, but when multiple events occur at the same time such as when a chord is pressed, N = 0,1,
The contents are memorized in the order of 2 …….

FIG. 2B shows a manipulator data buffer. The operation state of each investigator 2a to 2e is fetched and stored in this buffer.

FIG. 3C shows a channel register. In this register, the key-on data assigned to each of the eight tone synthesis sections (hereinafter referred to as “channels”: c = 0 to 7) of the tone generator 18 are stored. As key-on data, state flag ST (c), key number KN (c), key scaling data KS (c), key touch data KT
(C) and Assign Voice ASS (c). Here, the state flag ST (c) is a 2-bit flag that stores how the musical tone is currently sounded. When the flag is "10", it indicates that the key is on. A value of "" indicates that the key is released after key-off (reverberation sound is being generated), and a value of "00" indicates that no musical sound is assigned to that channel. The key scaling data KN (c) is a key code (pitch data) designated by the turned-on key. Also,
In the case of an electronic keyboard instrument, the pitch designated by a certain key is not fixed and can be freely set by the performer in advance. A key scaling data KS (c) is obtained by searching. The assigned voice ASS (c) is a tone color (voice number) of a musical tone generated in response to key-on.

FIG. 3D shows a register group used during the timer interrupt operation of the CPU 10.

PAN (c, n) is a register for storing EG pan data of each element of the voice assigned to each channel (pan position data of the sound image calculated by the pan EG).

PEG (c, n) is a register that stores in which step the EG pan of each element is. The EG pan step refers to which target value (PL (s) (m, n)) at that time.

DEG (c, n) is a register that stores the advance angle of the LFO when the main controller is the LFO.

R (c, n) is a register that stores the change rate at each step of the EG pan. This rate of change is PR (s)
Calculated from (m, n).

T (c, n) is a timer register for counting the delay time.

PNB (n) is a final pan data buffer that combines pan data from the main controller, sub controller, and EG pan. This register is provided for each element of one voice. This data is sent to the musical sound synthesizer (sound source device 18) and used as a parameter of the generated musical sound. Since the data is sent to the musical sound synthesizer for each channel, it is sufficient for this register to have one channel (4 elements).

EG (c) is sound level EG data. This data is also calculated by the timer interrupt operation.

c is a channel counter and n is an element counter, and these registers are incremented by 1 in order to process all the elements in the timer interrupt operation. m is a voice number pointer, s is an EG pan step pointer, and the value of PEG (c, n) is substituted each time.
These pointers are pointers for referring to the voice data storage area.

SF is EG with main controller and sub controller
It is an EG bias data register that stores data.

VL is a main pan bias data (pan bias data by the main controller) storage area, and RT is a sub pan bias data (pan bias data by the sub controller) storage area.

BB is a buffer area that captures the operation amount of the sub controller.

FIG. 1 is a flowchart showing the operation of the control unit of the electronic keyboard instrument, and FIGS. 5 (A) to 5 (E) are diagrams showing display examples on the display unit 3. The operation of the electronic keyboard instrument will be described with reference to these figures.

FIG. 1 (A) is a main routine. This operation starts when the power of the electronic keyboard instrument is turned on. First n1
The initial operation such as clearing the buffer is performed with and the main screen is displayed after the initial operation is completed. In this state, the on / off event (n3) of the keyboard 1 and the operation of the operator 2 connected to the operator interface 17 are accepted (n5), and when there is an event, the corresponding subroutine (n4, n6) is executed. To do. In addition, execute the main volume control etc. of the tone being sounded, (n7),
The operations of n3 to n7 are repeated while the power is on.

FIG. 6B shows a key event subroutine. When a key on / off event occurs, the data is loaded into the key event buffer (see Fig. 4 (A)) (n1
0), it is determined whether the event is a key-on event or a key-off event (n11). If it is a key-on event, a tone generation channel (tone synthesis section: c) is assigned to the keyed-on tone (n12), and the assigned channel register (see FIG. 4 (C)) has the key number KN (c) and key scaling. Write data KS (c) and key touch data KT (c), and state flag ST
Write "10" in (c) (n13). Next, the voice to be sounded on this channel is determined from the key number or the like and written to the assign voice register ASS (c) (n14), and these data are sent to the channel c of the tone generator 18 to start sounding. (N15). The key event buffer that has stored this event data is cleared (n16), and if there is next buffering data, it returns to n11 (n19).
If there is no next buffering data, the process directly returns.

On the other hand, if the captured data is a key-off event, the channel to which the key that was turned off is assigned is searched (n17), and the ST of that channel register is searched.
Rewrite (c) to "01" and proceed to (n18) n16.

FIG. 6C is a manipulator event subroutine. When a manipulator is operated, its operation input is fetched into a manipulator data buffer (see FIG. 4B) (n20), and this operation input is a screen selection input. It is determined whether there is a cursor movement input or a data setting input (n21 to n23).
If it is a screen selection input (n21), the display screen of the display unit 3 (see FIG. 5) is switched to the instructed screen (n24), and the cursor is displayed at the home position of that screen (n2).
Five). Set the address pointer in the register where the cursor is displayed (n26). This address pointer points to the addresses of the various registers shown in FIGS. 3 and 4, and data can be set in the register at the instructed address. If it is a cursor movement input (n22), the cursor display is moved according to the input state (n27), and the address pointer is updated correspondingly (n28). On the other hand, if it is a data setting input, the input data is set in the register area indicated by the address pointer, and the contents displayed on the display 3 are changed so as to match the input data (n30). After these operations, the operator data buffer is cleared (n31) and the process returns.

By this operation, the data in the voice data storage area shown in FIG. 3 can be updated. For example, FIG. 5 (A) is a screen for accepting input of voice static pan data SPAN (m), FIG. 5 (B) is a screen for accepting designation of a main controller (pan source), and FIG. ) Is a screen for accepting the designation of the sub-controller, and (D) and (E) in the same figure are screens for accepting the EG pan data set. When the setter (player) displays such a screen on the display unit 3 and then moves the cursor to a predetermined position and inputs data, the data in the column indicated by the cursor is updated.

FIGS. 1D and 1E show the timer interrupt operation. This operation is executed by interruption of the timer 19 at every predetermined timing. When this operation is started, 0 is set in each of the channel counter c and the element counter n (n37), and this operation is performed from the 0 element of channel 0. First, the voice assigned to the channel c is set in the voice number pointer m (n38), and the state flag ST (c) of the channel c is set.
Is referred to (n39). If ST (c) is "00", channel c is not sounding, so the following processing is omitted and n7
Jump to 5. If ST (c) is "10" or "01", the static pan data SPAN (m) of the voice m assigned to the channel c is judged because it is sounding (n40). If the content of SPAN (m) is not -51, static pan is set, so pan data is determined based on this data, stored in the pan data buffer PNB (n41), and sent to the sound source device 18. Jump to n71 to create data. If the content of SPAN (m) is -51, the dynamic pan is set and the operation of n42 and below is performed.

First, in n42, it is determined whether or not the element currently being processed is selected as the sounding element by the select flag SN.
Judging from (m, n), if not selected, jump to n69 to perform the operation for the next element. N43 if this element is selected
In, the sub-pan bias data RT is calculated by the sub-controller (n43: see (F) in the figure). After that, the main controller is determined by referring to the source assign flag VKL (m) (n44). KT (c) if key touch data KT (c) is specified for the main controller
Source depth data SCD to indicate control strength to
Multiply (m) to calculate the main pan bias data VL (n45). If the key number KN (c) is designated for the main controller, VL is calculated by the calculation of KN (c) × SCD (m) (n46). On the other hand, when the main controller is an LFO, its oscillation operation is executed at n47 and n48. That is, at n47, VL = 1-COS (DEG (c, n))
Is calculated to calculate VL.
Step (c, n). This step calculation is performed by DEG (c, n) = DEG (c, n) + CONST (c, n) .MOD.360.

Next, the pan bias data SF is calculated by VL × RT (n49), and ST (c) is determined again (n50). If ST (c) is "10", it means that the key is on, so the routine proceeds to n51 to judge the EG pan step PEG (c, n). On the other hand, ST (c) is "0".
If it is 1 ", the reverberation sound is being generated and the value of EG pan step data PEG (c, n) is judged at n52. If PEG (c, n) is less than 5, this operation is performed first after key-off. Since it is that (PEG (c, n) <5 is the step during key-on), PEG (c, n) ← 5 was input (n53) and the pan rate R (c, n) was determined. Afterwards (n54: See the same figure (G)) n61
Proceed to. If n52 has PEG (c, n) of 5 or more, that is, 5 or 6, the process proceeds to n51.

At n51, PEG (c, n) is determined. If it is 0, the delay time is in progress, so the process proceeds to n55 or less, and if not, the process is at EG pan, so it proceeds to n61 or less.

With the n55, the delay time is being set, so EG Pan Data PAN
The first key-on-pan level PL (0) (m, n) for (c, n)
, And compare the timer register T (c, n) with the direct time data TD (m, n) (n56). If they are not equal, delay time continues again and T (c, n) is set to 1 After adding (n57), proceed to n60. On the other hand, T (c, n) = TD (m, n)
In the case of, since the delay time has elapsed, the timer register T (c, n) is cleared and the EG pan step register PEG
Set (c, n) to the next step, 1 (n58),
Determine a new EG pan rate R (c, n) (n59), n60
Proceed to.

Below n61 is EG pan operation. In this operation PEG
The value of (c, n) is substituted for s. First, EG Pandata PAN
The pan rate R (c, n) is added to (c, n) to generate new EG pan data (n61). Next, it is determined whether or not the new PAN (c, n) has exceeded the target value PL (s) (m, n) (n62). If it has not exceeded, this EG pan step continues and the process proceeds directly to n60, and if it has exceeded, the current EG pan step PEG (c, n) is determined to proceed to the next EG pan step (n63). PEG if PEG (c, n) is other than "4" or "6"
Add 1 to (c, n) (n64) to create a new EG pan rate R
After determining (c, n), proceed to (n67) n60. Also PEG (c,
When n) is “4” and “6”, it is necessary to loop the EG, so when PEG (c, n) = 4, LOOP (m,
Substitute n) (n65). When PEG (c, n) = 6, 5 is substituted for PEG (c, n) (n66). After this, proceed to n67.

At n60, the pan data PNB (n) is calculated and stored by adding the pan bias data SF to the EG pan data PAN (c, n).
This pan data for one channel is sent together to the sound source device 18. After that, 1 is added to n (n69) to execute the same operation for the next element, and n39 is returned until n becomes 4 (n70). If n becomes 4, it means that the above operation has been executed for 4 elements (n = 0 to 3). Therefore, EG based on the pan data, EG data group, etc.
Calculate (c) (n71). The calculated value of EG (c) is the lowest sounding level MIN (stored in ROM 12).
If it is smaller (n72), the channel c is cleared (ST (c) = "00"), assuming that the sound is muted (n74), and EG
If (c) is MIN or higher, this EG
The tone data including (c) and PNB (n) is sent to the tone generator 18 (n73). After this, in order to execute the same operation for the next channel, 0 is set to n, 1 is added to c, and the process returns to n41. If the addition result c becomes 8, it means that the above operation has been completed for all the channels 0 to 7, and the process returns.

FIG. 6F is a subroutine for determining the sub bias data RT. First, depth control flag AM (m)
To determine whether the sub-controller is an LFO or a controller (n80). If AM (m) is set, the sub-controller is an LFO, so the current value of the LFO is read into the buffer BB (n81), and the value of this BB is multiplied by the LFO depth data LD (m) that is the control strength. Set as RT (n82). Meanwhile A
If M (m) has been reset, the sub-controller is one of the operators, so it is determined by the controller assign flag COLR (m) which operator is specified (n83). Bias depth data BD (m), which is the control strength, is stored in the buffer BB with the operation amount data of the specified manipulator stored in the buffer BB (n84).
Is multiplied to obtain LT (n85). After the above operation, it returns.

Further, FIG. 9G is a subroutine for determining the EG pan rate R (c, n). First, the current EG pan data PAN (c,
n) is compared with PL (s) (m, n) which is the next target value (n92). If PAN (c, n) is larger, it will be necessary to pan in the negative direction from now on, so the pan rate PR (s) (m, n) corresponding to this step is made negative and R (c, n) Set to (n94). Otherwise, the pan level PL (s) (m,
n) is set as it is to R (c, n) (n93). Then return.

As described above, in this embodiment, since the EG pan and pan bias can be applied to each element constituting the voice to move the localization, extremely complicated localization control of the musical sound can be performed. Further, since the pan bias is a combination of two types of a main controller (source) and a sub controller (bias), more complicated control is possible. Of these, the main controller extracts the parameters from the actual performance of the keyboard, so it can express the nuances of the performance well, and the sub-controller extracts the parameters from the operation of controls other than the keyboard. It can give an additional effect. Further, in this embodiment, the EG pan is performed linearly by adding the rates, but it is also possible to perform the curve pan by multiplying the value of PAN (c, n) by the rate, for example.

In addition, in this embodiment, the tone color is set by the key code for the polyphonic correspondence, but it is set as the monotone correspondence.
Modifications such as using eight channels to produce eight tones corresponding to one key code are also possible.

(G) Effects of the Invention As described above, according to the electronic musical instrument of the present invention, it is possible to perform pan control for each of a plurality of waveform elements that make up one musical tone (timbre). Even when a musical tone is pronounced, the spread of the musical tone can be enriched. Further, since the pan control can be performed by a plurality of control means, that is, the main control means and the sub-control means, it becomes possible to perform complicated pan control according to the performance, and the degree of freedom of pan control is improved.
In this case, since the maximum moving range of the sound image by each control means can be set individually, it is possible to realize the sound image moving effect suitable for the playing mode and the music.
