Abstract

PURPOSE:To generate a sound with an original sound image fixed position or a sound volume of each element which constitutes a timbre during a test hearing to select the timbre. CONSTITUTION:For the case of a voice selection mode, signals are circulated in the loop constituted by steps SPg5, SPg6, SPg8, Spg9, SPg10 and SPg5. In this case, an element pan information EPANiPT and an element volume information EVOLiPT are transmitted to an assigned channel in the step SPg6. Therefore, a sound is generated with an original sound image fixed position and a sound volume of each element which constitutes a voice. On the other hand, in the case of other modes (including an automatic performance), a step Sdg7 processing replaces the step SPg6 of the loop and both sound image fixed position and a sound volume are affected by the data set for the parts.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument which, when changing a tone color set for each part, makes it easy to hear the sound image localization and volume of the tone color to be changed.

[0002]

2. Description of the Related Art In an electronic musical instrument, it is common to drive a plurality of sound generation channels in a time-division manner to produce a polyphonic sound. In addition, information designating the tone color of the sound generation channel is defined as an element. There is one in which a plurality of these elements are used to compose one musical tone. Here, a musical tone composed of a plurality of elements is called a voice, and an attack, decay,
Sound generation processing such as sustain is performed in units of voice.

By the way, the sound image localization (pan) and the reference volume are set for each element.
For example, the element 1 has a volume value a at the center, the element 2 has a volume value b toward the left, and the element 3 has a volume value c toward the right. For example, in the case of a piano voice, if the treble side of the component is set to the right and the bass side is set to the left, the keys are turned on from the bass to the treble. Sounds like a transition to and can enhance the sense of presence.

In recent years, electronic musical instruments have been developed in which performance information divided into a plurality of parts is played by a different voice for each part. In this case, the sound localization and volume are also set for each part. Therefore, for example, if a voice composed of an element that was localized in the center is assigned to a part and the sound image of that part is localized to the left, the voice will be moved from the leftward position. Is pronounced. The same process is performed for the volume.

[0005]

By the way, in the above-described electronic musical instrument, the sound of the entire ensemble is often created while appropriately changing the tone color and volume of each part, and the voice once determined. Even with (timbre), a request may be made to change it later.

Therefore, in this type of electronic musical instrument, the tone color of the designated part, that is, the voice, can be changed. When changing this voice, the operator
The candidate voices are sequentially selected, and the suitability is judged while listening to the sound.

However, in the conventional electronic musical instrument, when the part is designated, the localization and volume of the sound image are influenced by the set value of the part. For this reason, depending on the part, the volume may be low or sound may be produced from a position where it is difficult to hear, and it is not possible to audition with the original localization and volume of that tone, making it difficult to select a tone (voice selection). There was a problem.

The present invention has been made in view of the above-mentioned circumstances, and in the audition when selecting a tone color, each element constituting the tone color is caused to sound in the original sound image localization, whereby the tone color is selected. The purpose is to provide an electronic musical instrument that is easy to perform.

Another object of the present invention is to provide an electronic musical instrument which makes it easy to select a tone color by making a sound at the original volume of each element constituting the tone color in a trial listening when selecting a tone color. It is intended to be provided.

The operation signal output from the operation unit 16b is supplied to the CPU 1.

B: Operation of Embodiment Next, the operation of this embodiment having the above-mentioned configuration will be described. FIG. 7 is a flow chart showing the main routine of this embodiment. First, in step SPa1, initialization is performed and initial values are set in various registers and the like. Then, in step SPa2, keyboard processing is performed. In the keyboard processing, each key of the keyboard is scanned, and processing such as sounding and muting according to the state of each key is performed. Next, when proceeding to step SPa3, a mode switch process and a part switch process are performed. These switches are switches provided in the operation unit 16b, and the switch signals are always valid regardless of the mode described later.

The mode switch is a switch for selecting any one of modes 0 to 3, and in the next step SPa4, it is determined which mode is selected. Depending on this determination result, step S
One of the voice selection process of Pa5, the song process of step SPa6, the voice edit process of step SPa7, and the other processes of step SP8 is performed. When the processing of these steps SP5 to SPa8 is performed, the processing returns to step SPa2, and the above processing is repeated thereafter.

In step SPa3, one of the parts is selected based on the part switch signal. Here, the reason for selecting the part is as follows.

That is, there are a maximum of 16 performance parts for automatic performance, but when recording performance data in these parts, it is necessary to specify one of the parts. Also, it is necessary to specify a part when specifying or editing the voice of each part. Therefore, one of the parts is selected by the part switch described above. When a key on the keyboard is operated, sound generation processing is performed with the tone color and volume of the selected part.

Here, the operation of the switch processing in step SPa3 is shown in FIG. When the ON event of the mode switch is detected, step SPb shown in FIG.
In 1, the mode number corresponding to the operated switch is stored in the register MD, and then in step SPb2, the display corresponding to the mode number in the register MD is displayed on the display unit 16a. Therefore, the operator can know which mode has been selected, and also can know the operation method in that mode from the displayed contents.

When the part switch on event is detected, the part number corresponding to the operated part switch is stored in the register PT in step SPc1 shown in FIG. 8B, and then the register is registered in step SPc2. The display corresponding to the part number in the PT is displayed on the display unit 16a. Therefore, the operator can know the selected part number in the same manner as when the mode is selected.

Next, each processing of steps SPa5 to SPa8 will be described. (1) Song Processing The song processing is processing relating to a song, such as selecting one of the song data transferred from the floppy disk FD to the area E3e of the RAM 3, and when the song mode is selected by the mode switch, step SPa
Song processing of No. 6 is performed. Here, FIG. 9 is a subroutine showing one process in this song mode.

First, in step SPd1 shown in FIG. 9, the designated song number is transferred to the register SN. Then, in step SPd2, the multi-number in the song data SD _SN ( _SN is the song number in the register SN). The data MD is transferred to the multi-buffer MB. That is, the plurality of song data selectively read from the floppy disk FD is stored in the area E3e in the RAM3.
(See FIG. 2B), but in this case, only the multi-data MD (see FIG. 4) in the song data corresponding to the song number in the register SN is further added to the multi-buffer MB (see FIG. 2 ( It is transferred to area 3c) of b).

Then, the process proceeds to step SPd3, and multi-voice data MV1 to MV16 in the multi-buffer MB.
The voice data corresponding to the voice number indicated by is transferred to the voice buffers VB1 to VB16. The voice data transferred in this case is designated by the multi data in the song data, and is appropriately selected from the preset voice and the user voice.

Next, in step SPd4, the contents of the working area E3a are rewritten according to the other setting information in the song data SD _SN , and then in step SPd.
5, the display contents of the display section 16a is changed to the song data S
_Switch to the display for D _SN and return. As described above, you can select any song data,
In response to a play switch-on event during song processing (not shown), automatic performance based on the selected song data can be started.

(2) Voice selection processing When the voice selection processing is designated by the mode switch, the voice processing of step SPa5 is executed. When a voice selection operation is detected during voice processing, the subroutine shown in FIG. 6 is activated, and the designated voice number is assigned to the buffer buf (step SPe1). In this case, the voice number of the user voice is UV0 to UV1.
27 and preset voices are PV0 to PV127.
Then, set the value of the buffer buf to the voice number VN _PT in multi-buffer MB (step SPe2). In this case, _PT of the voice number VN _PT is a part number that has been selected by the part switch.

Then, in step SPe3, the voice data VD _buf designated by the buffer buf is transferred to the voice buffer VB _PT (where _PT is the part number selected by the part switch as in the above case). Through the above processing, the voice data in the multi-buffer MB is changed. However, what is rewritten in this subroutine is the data in the multi-buffer MB, and the voice data in the song data is not changed.

Next, in step SPe4, the voice data (tone color) indicated by the buffer buf is displayed on the display unit 16a as the tone color of the selected part. Then, after this processing, the process returns.

(3) Multi-store event This process is a process for writing the multi-data MD in the multi-buffer MB to the designated song data in accordance with the instruction of the panel switch. For example, the multi-buffer M
It is performed after editing or changing the multi-data MD using B.

In this process, first, in step SPf1 shown in FIG. 10, the designated song number is stored in the register S.
Then, in step SPf2, the multi data in the multi buffer MB is stored in the song data SD.
_It is transferred to _SN ( _SN is the value of register SN) and rewritten.

As described above, the multi-data in the song data SD is rewritten only when the multi-store event process is performed. Since the multi-voice data MV in the multi-buffer MB is rewritten for each part, if desired parts are sequentially designated and rewritten, the multi-store event process shown in FIG. The data for those parts in the data are rewritten all at once.

(4) Key-on event Next, the key-on event in the keyboard processing (step SPa2) will be described with reference to FIG. First, the note number of the key that has been keyed on is substituted into the register NN in step SPg1. Then, the number of elements written in the voice buffer VB _PT (where _PT is the selected part number) shown in FIG. 2B is substituted into the register n (step SPg2). That is, the voice buffer VB
_As shown in FIG. 3, the number of elements forming a voice is written in the voice data in the _PT , so that number is substituted.

Next, in step SPg3, n tone generation channel allocation processing is performed. That is, the tone generation channels in the tone generator 5 shown in FIG. 5 are allocated by the number of elements set in step SPg2. Then, in step SPg4, 1 is set in the register i. The register i is a register that counts the number of times of loop processing described later and indicates the number of the assigned sounding channel.

Then, in step SPg5, it is determined whether the register MD is 0 or not. The register MD is shown in FIG.
The contents are set by the mode switch process of step SPa3 shown in (1), and the values “0”, “1”, “2”, and “3” corresponding to the modes 0, 1, 2, and 3 are held. If the determination in step SPg5 is "NO", that is, if a mode other than the voice selection process is selected, the process proceeds to step SPg7 and the element pan information EP
AN _iPT and multi-pan information PAN _PT are combined, element volume information EVOL _iPT and multi-volume information VOL _PT are combined, and these _pieces of information are sent to the i-th assigned channel.

In this case, the synthesis of the volume information is a process of calculating the multiplication value of the element volume information and the multi-volume information (volume for part). In addition, the composition of the pan information is performed by the element pan information EP
_This is done by multiplying the AN _iPT and the multi-pan information PAN _PT . Here, FIG. 12 to FIG.
This will be described with reference to FIG. First, the multi-pan table 20 and the element pan table 2 shown in FIG.
Reference numeral 1 is a table provided in the area E2c of the ROM 2, respectively. The multi-pan table 20 converts the multi-pan information PAN _PT into left and right volume data (logarithmic value), and the element pan table 21 converts the element pan information EPAN _PT into left and right volume data (logarithmic value). Convert. FIG. 13 shows a multi-pan table 20.
Is a graph showing the conversion characteristics of the left side volume data, the volume value is maximum when the multi-pan information PAN _PT indicates left (L), and the maximum value when the center (C) is indicated. On the other hand, the value is -3 dB lower. When the multi-pan information _PT indicates the right (R), the volume value becomes 0. Further, the conversion characteristic of the right side volume data of the multi-pan table 20 is opposite to the characteristic shown in FIG. 13, that is, the characteristic in which L and R on the horizontal axis are exchanged.

FIG. 14 is a graph showing the conversion characteristic of the left side volume data of the element pan table 21.
The maximum value is held between the left (L) and the center (C), and the volume value decreases from the center (C) to the right (R). The volume data on the right side has a characteristic in which L and R on the horizontal axis shown in FIG. 14 are interchanged. And
From the multi-pan table 20 and the element pan table 21, right-side and left-side volume values (logarithmic values) are output according to the characteristics described above, and the respective left-side volume values are added by the adder 22, and the respective volume values are added. Right side volume value is adder 2
It is added by 3. Since the output signals of the adders 22 and 23 are logarithmic value added values, the pan information PAN _PT , EPAN
_The value corresponds to the volume multiplication based on _PT . The output signals of the adders 22 and 23 are sent to the i-th sounding channel.

Next, in step SPg8, data such as the note number in the register NN, the waveform number in the voice element VEi _PT , the EG control information, and the filter control information is sent to the i-th assigned channel. Then, in step SPg9, it is determined whether or not the value of the register i has reached the number of elements in the register n. If "NO", the value of the register i is incremented by 1 in step SPg10, and then the process proceeds to step SPg5. Return. Thereafter, similarly, steps SPg5, SPg7, SPg
When the processing for all the elements is completed by cycling through 8, SPg9, SPg10, SPg5, step SP
The determination of g9 is "YES", the process proceeds to step SPg10, and note-on signals are sent to the n allocated channels. As a result, the tone generator 5 generates a musical tone signal having a pitch corresponding to a key-on key, and a tone color, a volume, and a sound image localization of the selected part, and the tone system 6 emits the tone signal. In the key-on event routine, a routine relating to recording of performance data is omitted. However, at the time of recording, note-on event is written in the performance data in step SPg1 for detecting the note number of the depressed key. You can do this.

On the other hand, if the voice selection mode is selected, the determination at step SPg5 becomes "YES", and steps SPg5, SPg6, SPg are repeated until the value of register i becomes equal to the number of elements in register n.
It circulates through a loop of 8, SPg9, SPg10, and SPg5. That is, step SPg in the above loop
It becomes a loop process of performing the process of step SPg6 instead of 7. Then, in step SPg6, the element pan information EPANi _PT and the element volume information E
VOLi _PT is sent to the assigned channel. For this reason,
When the loop process is completed and the process of step SPg11 is performed, sound is localized by the sound image localization of each element forming the voice and sound is generated. Therefore, the operator
In trial listening when selecting a voice (tone), a musical tone can be heard by the original sound image localization and volume of each element forming the voice.

(5) Other Processing The other processing of step SPa8 also includes automatic performance processing. In the automatic performance processing, the performance data of all parts are read and set for each part. Simultaneous performance by voice.

C: Modified Example In the above-mentioned step SPg7, the sound image localization and volume information are combined, but each part may be controlled by the sound image localization and volume described in the multi-data. Further, in the above-described embodiment, both the volume information and the pan information are controlled, but the control may be performed by omitting either the pan information or the volume information.

The selection can be facilitated. (Claim 1) Also, in the trial listening when selecting a tone color, the sound is produced at the original volume of each element constituting the tone color, thereby facilitating the tone color selection.
