Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a musical tone control device for an electronic musical instrument that controls the pitch, timbre, volume, effect, etc. of generated musical tones, and particularly relates to a musical tone control device for controlling the conditions of generated musical tones, such as the pitch, tone, volume, effect, etc. A plurality of groups of operator data for the operators that control the music are stored in advance in a storage device, and the state of the generated musical tone is set by sequentially reading out the multiple sets of stored operator data as the music progresses. The present invention relates to a so-called preset-type musical tone control device that can be changed.

[Conventional technology]

A preset type musical tone control device generally includes a plurality of preset operators, and stores a plurality of groups of musical tone control data in a storage device corresponding to the plurality of preset operators. The performer operates one of the preset controls as the music progresses, reads out the musical tone control data group corresponding to the operated preset control from the storage device, and determines the pitch, timbre, volume, effect, etc. of the generated musical tone. Change the settings. Therefore, the performer can change the settings of the generated musical tones simply by operating the preset controllers, without having to operate each of the multiple musical tone control operators arranged on the front panel of the electronic musical instrument. I can do it.

In addition, multiple sets of musical tone control data are stored in preset operators in advance according to the progression order of the music, and the performer operates a single operator, for example, a foot operator, as the music progresses. Select the preset controls in a predetermined order by reading out the musical tone control data group stored in the preset controls in order, and change the settings of the musical tone conditions such as pitch, timbre, volume, effect, etc. of the generated musical tone. A musical tone control device has also been proposed. According to this device, since the performer only has to operate a single operator while the music is progressing, it is possible to more easily change the settings of the musical tone state.

[Problem to be solved by the invention]

According to the general musical tone control device described above, the performer can change the setting of the musical tone state simply by operating any one of the plurality of virtual operators. However, since the preset operators are arranged in one or more rows on the front panel of the electronic musical instrument, it requires considerable skill for the performer to confirm and operate the desired preset operator during performance. In particular, the operation of phrases that require fast key playing requires a high degree of skill even for an expert.

Furthermore, a musical tone control device that changes the settings of the musical tone state by operating a single controller eliminates the need for the performer to operate the preset controller during performance, but this device does not change the settings of the entire electronic musical instrument. Limited to simultaneous switching,
In addition, the order in which preset controls are switched is always determined, so if there are multiple identical musical tone settings in a song, you can separately store identical musical tone control data groups in the corresponding storage areas of the storage device. This is disadvantageous in that it must be memorized and a large number of preset operators are required. Furthermore, if a foot operator is used as a single operator, for example, it is necessary to switch between the foot operator and other control functions, such as the start/stop control function for automatic rhythm play, and each time the foot operator is operated, There is the inconvenience of having to reselect the control function.

This invention aims to reduce the storage capacity by storing only the control data that needs to be changed in the storage device, and when reading out the control data stored in the storage device by operating a single operator. An object of the present invention is to provide a musical tone control device for an electronic musical instrument that can simultaneously switch control functions of one operator.

If they are turned on at the same time, the CPU 61 determines "rYes" and executes the preset process (step 304). If the memory switch 26a and the preset switch are not turned on at the same time, the CPU 61 returns "No".
It is determined that this is the case, the preset process is jumped, and the process returns to the operator event process 200. In the preset processing, the current state of each operator on the control panel 20 is stored in the memory 6 as a musical tone control data group corresponding to the operated preset operator.
In the process of storing in the PRDT (k, n) register in 4,
The details will be described later.

If the event of the memory switch 26a is an off event in the previous step 302, the CPU 61 determines "No", and then determines whether the electronic musical instrument is in the stop mode, that is, the MO

If the electronic musical instrument is in the memory mode, the CPU 61
” and moves the cursor CU (step 502
), store the horizontal and vertical positions of the cursor CU after the movement in registers i and j (step 503).
), the process returns to the operator event processing program 200. The movement range of the cursor CU on the display 29 is
As shown in Figure 3, there are 10 positions (i-1
~10), and three positions (j-1 to j-3) in the vertical direction.

Switch 11 The function switch process (step 206) is executed by reading the function switch process subprogram 600 shown in FIG. This process is performed when the electronic musical instrument is in the memory mode, when the function switch, that is, the rhythm start/stop switch 23.fill-in switch group 24.
When any of the function switches such as the preset switch group 25 is operated, the code of the operated function switch (see FIG. 5) is preset at the position indicated by the cursor CU in the display 29, and the electronic When the musical instrument is in a mode other than the storage mode, processing is performed to perform the unique function of the operated function switch.

First, the CPU 61 determines whether the content of the MODE register is "1", that is, whether the electronic musical instrument is in the storage mode (step 601).
61 determines rYes, 1, and stores the code of the operated function switch in the MD in the panel preset data memory 64.
[i, jl Store in register (step 602
). M D [i l 31 Register variables i and j are data stored in registers i and j in the working memory 63, and indicate the current position of the cursor CU. The CPU 61 then displays the contents of the function switch stored in the MD[i,j] register at the position of the cursor CU on the display 29 (step 603), and moves the cursor CU to the next position (step 604).
, stores the position of the moved cursor CU in registers i and j (step 605).

If the electronic musical instrument is not in the storage mode, the CPU 61 determines "NO" in step 601, and performs processing according to the function of the operated function switch.

First, the CPU 61 determines whether or not the preset switch group 25 has been operated (step 606), and if so, performs preset execution processing (step 607).
The details of this preset execution process (step 607) will be described later. If the operated function switch is the fill-in switch group 24, the CPU 61 proceeds to step 60.
6, the determination is "NO", and the subsequent step 608 is "Yes".
”, the switch number of the operated fill-in switch is set in the Fl and N registers in step 60.
9) The set switch number and fill-in start signal are sent to the automatic accompaniment circuit 40 via the system bus BS.
(step 61O). The automatic accompaniment circuit 40 receives this signal and instead of the rhythm pattern of the selected rhythm switch, sends out the fill-in pattern of the operated fill-in switch to the musical tone signal generation circuit 50 via the system bus BS for a certain period of time. If the operated function switch is the rhythm start/stop switch 23, the CPU 61 makes a "NO" determination in step 608, executes the rhythm switch process (step 611), and returns to the operator switch process 200. Details of the rhythm switch processing will be described later.

Footswitch 12 The footswitch process (step 207) is executed by reading the footswitch process subprogram 700 shown in FIG. This foot switch process detects the operation status of the foot controls, and when the electronic musical instrument is in the read mode, reads out each group of function switch control codes preset on the display 29 to generate musical tones. pitch, tone.

Change settings such as volume, effects, rhythm, etc. Furthermore, when the electronic musical instrument is in the stop mode, automatic rhythm performance start/stop control is performed.

First, the CPU 61 determines whether the electronic musical instrument is in the read mode, that is, whether the content of the MODE register is "2" (step 70). If the electronic musical instrument is in the read mode, the CPU 61 determines ``Yes'' and sets ``1'' in the register j of the working memory 63 in step 70.
2) Load the contents of the M D [i, jl register in the memory 64 in which the operator code of the function switch is stored into the X register in the working memory 63 (step 703).

Next, the CPU 61 determines the contents of the X register (step 704) and performs processing according to the operator code stored in the X register. That is, if the operator code stored in the X register is from "1" to "16", it is the operator code for the preset switch group 25, and therefore preset execution processing is performed (step 705). If the control code is "17" to "19", it is the control code for the fill-in switch group 24, so subtract "16" from the control codes r17J to "19" to obtain the fill-in switch number, and is stored in the FLN register (step 706). Then, the fill-in switch number stored in the FLN register and the fill-in start signal are sent to the automatic accompaniment circuit 40 to start the fill-in of the automatic rhythm performance (step 707). If the operator code is "20", this is the operator code for the rhythm start/stop switch 23, so rhythm switch processing (step 708) is performed. Preset execution processing (
Details of step 705) and rhythm switch processing (step 708) will be described later.

When these processes are completed, or when the operator code stored in the X register is a code other than "1" to "20", the CPU 61 increments the contents of register j (step 709). but"
3'' (step 710). If the contents of register j do not exceed "3", step 70
Return to step 3 and repeat the above process. If the contents of register j exceed "3", it means that all the i-th control data group preset on the display 29 has been read, so next, the value of register i and the value of NDATA register are read. (step 711). The NDATA register stores the number of operator data groups (1 to 10) preset on the display 29 when the electronic musical instrument is in the storage mode. Therefore, if the value of the register i and the value of the NDATA register do not match, it means that the preset operator data group still remains on the display 29, so when the next foot switch process is performed, the operator The contents of register i are incremented so that the data can be read (step 712). When the value of the register i and the value of the NDATA register match, it means that the reading of the control data group on the display 29 by the operation of the foot control has been completed, so the contents of the MODE register are set to "0".
is set to switch the electronic musical instrument to the stop mode (step 713), and the process returns to the operator event processing 200.

In the previous step 701, if the electronic musical instrument is in a mode other than the read mode, the CPU 61 determines "NO", and then determines whether the content of the MODE register is "0", that is,
Determine whether the electronic musical instrument is in stop mode (step 720
). If it is the stop mode, the CPU 61 determines "Yes" and performs the rhythm switch process (step 721), which will be described later.
is executed and the process returns to the operator event processing 200.

If it is not in the stop mode, the electronic musical instrument is in the recording mode, so the CPU 61 determines "rNo" (step 720).
, jumps to the rhythm switch process and returns to the operator event process 200.

Preset Process 13 The preset process (step 304) in the memory switch process 300 (FIG. 8) described above is executed by reading out the preset process subprogram 800 shown in FIG.
Any preset switch in 5 and memory switch 2
6a are operated at the same time, the operation status of each operator on the control panel 20 is stored in the PR in the memory 64 as a musical tone control data group corresponding to the operated preset switch.
This is the process of storing in the DT(k, f) register.

First, the CPU 61 sets the switch number of the preset switch where the event occurred in the PRN register (step 801), and then sets the initial value "1" in the register n (step 802). Then, P RD with the contents of the PRN register and the contents of register n as variables.
Data indicating the operating state of the operator corresponding to control element n on the control panel 20 is set in the T (PRN, n) register (step 803). Next, the CPU 61 increments the contents of variable register n in step 8.
04), it is determined whether the contents of register n exceeds "20" (step 805). If the contents of register n exceed r20J, it means that all control elements have been read, and the process returns to memory switch processing 300.

If the contents of register n do not exceed "20", the process returns to step 803 and the above-described process is repeated until the contents of register n exceeds "20".

14. The preset execution processing (steps 607 and 705) in the function switch processing 600 (FIG. 11) and foot switch processing 700 (FIG. 12) described above is the preset execution processing shown in FIG. The subprogram 900 is executed by reading the subprogram 900. In this process, by operating a preset switch in the preset switch group 25 or reading its operator code, the tone control data group corresponding to the switch is transferred to the PRDT (k, f) in the memory 64.
) This is a process of reading from the register and changing the settings of the generated musical tone.

First, the CPU 61 sets the switch number of the preset switch where the event occurred in the PRN register (step 901), and sets the initial value "1" in the register n (step 901).
Step 9o2). Next, the contents of the PRDT (PRN, n) register are sent to the musical tone signal generation circuit 50 (step 9o3), and the registers between the PRDT (PRN, n) register are set to values corresponding to the current state (step 9o4). . Next, register n is incremented (step 9o5), and it is determined whether the contents of register n exceed r20J (step 9o6). If the content of register n exceeds ``20J'', it means that reading of all control elements has been completed, so the CPU 6 returns to function switch processing 600 or foot switch processing 700. If not, the process returns to step 903 and repeats the above-described process.

Rhythm Switch 15 The rhythm switch processing (steps 611, 708, 721) in the function switch processing 600 (FIG. 11) and the foot switch processing 700 (FIG. 12) described above is performed by the rhythm switch processing subprogram 10 shown in FIG.
Execute by reading 00. This process is a process for controlling the start/stop of automatic rhythm performance by operating the rhythm start/stop switch 23 or reading its operator code.

First, the CPU 61 inverts the PRUN register (step 1001), and determines whether the inverted content of the PRLIN register is "0", that is, whether or not it is in a rhythm stop state (step 1002). ”, it means that automatic rhythm performance has been performed up to now, so the CPU 61 selects “Yes”.
Then, a rhythm stop signal is output to the automatic accompaniment circuit 40 to stop the automatic rhythm performance (step 1003).
). If the content of the inverted PRUN register is "1", the CPU 61 determines "No" in step 1002,
A rhythm start signal is output to the automatic accompaniment circuit 40 to start automatic rhythm performance (step 1004). When the process of step 1003 or step 1004 is completed, the CPU 61 returns to the function switch process 600 or the foot switch process 700.

(To) In the above-described embodiment, a foot operator was used as an example of a single operator, but the present invention is not limited to this, and other operators such as a knee lever may be used.

Further, the function switch to be preset on the display 29 is not limited to the above-mentioned embodiment, and may be a tone color switch, for example.

Further, the number of function switches preset on the display 29 per round is not limited to "3", but may be any number. Furthermore, without being limited to a specific number, the number of data may be changed for each set by using a data end symbol.

Further, in the above-described embodiment, when all the functional switch group data preset on the display 29 has been read out,
Although the electronic musical instrument is returned to the stop mode, the read mode may be continued to repeatedly read out the function switch group data.

〔Effect of the invention〕

According to this invention, only the controller data of the controllers that need to be changed is stored in the storage device, so it is possible to reduce the storage capacity. When reading out by operating the child, the control function of this single operator can be switched at the same time, making it easier to change the settings of the musical tone state during performance compared to conventional musical tone control devices. , it is possible to improve performance operation performance of an electronic musical instrument.
