Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timbre in which a plurality of timbre groups each comprising one or more timbres, and a basic timbre number is assigned to each timbre group. The present invention relates to an electronic musical instrument provided with a sound source in which an arbitrary tone in a list is set and which generates a tone of the set tone. 2. Description of the Related Art Conventionally, MIDI (Musical)
Instrument Digital Interf
ace) The above-mentioned electronic musical instruments conforming to the standard are known. In the original electronic musical instrument when the MIDI standard was enacted, the generation of 128 tones was sufficient, but in the current electronic musical instrument, each of the initial 128 tones is used as a basic tone.
By adding various variations of tones to these basic tones, thousands of tones can be generated. In such electronic musical instruments to which variations are added, a tone group is created for each basic tone,
The timbre of the variation added to the basic timbre is added to the timbre group of the basic timbre. Therefore, in a conventional electronic musical instrument, when setting a tone for a sound source, two operations of selecting a tone group and an operation of selecting a tone in the selected tone group must always be performed. [0003] By the way, when an electronic musical instrument to which a new variation of tone is added is put on the market, the maker side,
I want customers to listen to the new tone at the store. [0004] However, in an electronic musical instrument in which the above two operations must always be performed in setting a tone for a sound source, a recommended tone that a maker wants to listen to is set in the sound source. In this case, it is necessary to search for the recommended timbre from among thousands of timbres while performing two operations, and it is very troublesome and time-consuming for a customer to set a recommended timbre as a sound source. In view of the above circumstances, it is an object of the present invention to provide an electronic musical instrument capable of easily setting a predetermined tone color to a sound source in a short time. According to the electronic musical instrument of the present invention which achieves the above object, an arbitrary tone in a tone list comprising a plurality of tone groups each comprising one or more tones is set and set. A basic tone color selecting means for selecting a basic tone number specifying a tone color group in an electronic musical instrument provided with a sound source for generating a tone of the selected tone color;
A variation selection means for selecting a variation number specifying one tone color, and a reference table in which a correspondence relationship between each basic tone number and any one tone color in a tone group to which the basic tone number is assigned is stored. A reference table storage section, a tone color setting mode switching means for switching the tone color setting mode, and a basic tone color selecting means when the tone color setting mode switching means switches to a predetermined first tone color setting mode. In response to the tone number being selected and the variation number being selected by the variation selecting means, a tone specified by the selected basic tone number and the selected variation number is set in the tone generator, and the tone color is set. When the mode is switched to the predetermined second tone color setting mode by the setting mode switching means, In response to the selection of the basic timbre number by the basic timbre selection means, the reference table is referred to, and the selected timbre group corresponding to the selected timbre group in the timbre group having the selected basic timbre number is assigned. And a tone color setting means for setting a tone color corresponding to the basic tone color number to the sound source. According to the electronic musical instrument of the present invention, predetermined tone colors such as recommended tone colors on the maker side are defined in the reference table, and the mode is switched to the second tone color setting mode. By selecting the basic tone number, the tone setting means sets the tone corresponding to the selected basic tone number associated with the reference table to the sound source. Can be set easily. Further, by switching to the first tone color setting mode, an arbitrary tone color in the tone color list can be set for the sound source.

Here, the electronic musical instrument 1 of this embodiment has two tone color setting modes, an automatic variation number assignment mode and a normal mode. In the variation number automatic assignment mode, when the basic tone color number is designated by operating the decrement key 153 or the increment key 154, the variation number of the designated basic tone number specified in the reference table shown in FIG. This is a mode for setting a tone color to the sound source 16. Such a variation number automatic assignment mode is automatically set in the electronic musical instrument 1 when the main power of the electronic musical instrument 1 is turned on. For this reason,
When the main power of the electronic musical instrument 1 is turned on and the decrement key 153 or the increment key 154 is operated, the tone that the maker wants the customer to listen to at the store or the like is set as the sound source 16, and the tone that the maker wants to listen to is set. The customer can listen to the music sound. In the normal mode, when both the basic tone number and the variation number are designated by operating the decrement key 153 or the increment key 154, the designated tone group in the designated tone group is assigned. This is a mode for setting the tone assigned with the variation number to the sound source 16. Therefore, the variation number automatic assignment mode corresponds to the second tone color setting mode according to the present invention, and the normal mode corresponds to the first tone color setting mode according to the present invention. The mode switching button 152 is an operator for switching between these two modes each time the button is pressed once. The shift button 151 is an operation element for determining whether the decrement key 153 and the increment key 154 function as a basic tone number selection means or a variation number selection means.

By operating a not-shown operator, the liquid crystal display panel 155 also displays the correspondence between the basic timbre numbers and timbres specified in the lookup table shown in FIG. Next, a processing routine of the CPU 12 in setting a tone color to a sound source of the electronic musical instrument will be described with reference to FIG. FIG. 5 shows C in the tone color setting process for the sound source.
It is a flowchart which shows the processing routine of PU. The timbre setting processing routine shown in FIG.
Is started by operating the decrement key 153 or the increment key 154 shown in FIG. At the start time, the basic tone color number is N, and the variation number is M. The basic tone color number N of the electronic musical instrument 1 immediately after the main power is turned on is 001, and the variation number M is 000. First, in step S1, it is determined whether a change in basic tone color number or a change in variation number has been instructed. When the decrement key 153 or the increment key 154 is operated in a state where the shift button 151 shown in FIG. 4 is not operated, it means that a change of the basic tone number has been instructed, and the process proceeds to step S2. , 154 is operated with the shift button 151 pressed down,
The instruction to change the variation number is given, and the process proceeds to step S6. First, the processing when the process proceeds to step S2 will be described. In step S2, this time, when the decrement key 153 or the increment key 154 is operated, it is determined whether or not the electronic musical instrument 1 is set to the variation number automatic assignment mode, and the electronic musical instrument 1 is set to the variation number automatic assignment mode. In this case, the process proceeds to step S3. In step S3, the instruction to change the basic tone color number is issued in the automatic variation number assignment mode, so that the basic tone color number is updated from N at the start to N 'of N ± 1 and updated from the reference table shown in FIG. The variation number f (N ′) corresponding to the basic tone number N ′ is read out. Thereby, the variation number is updated from M at the start to M ′, and the updated variation number M ′ is f
(N '). Subsequently, in step S4, the tone color of the updated basic tone color number N 'and the updated tone number of the variation number M' is set in the sound source 16. As a result, the sound source 16 uses the musical tone waveform data of the set timbre to generate performance information generated by the performance operation and the RAM 1.
3 or a musical tone based on the automatic performance information recorded in the ROM 14. On the other hand, in step S2,
Decrement key 153 or increment key 1
If the electronic musical instrument 1 is not set to the variation number automatic assignment mode when the electronic musical instrument 54 is operated, that is, if the electronic musical instrument 1 is set to the normal mode, step S
Go to 5. In step S5, when the change of the basic tone number is instructed in the normal mode, the basic tone number is updated from N at the start to N 'of N ± 1, and the variation number is inherited from M at the start as it is. After updating to M ', the process proceeds to step S4. Next, a case in which the flow proceeds from step S1 to step S6 due to an instruction to change the variation number will be described. In step S6, since the change of the basic tone number is not instructed and the change of the variation number is instructed, the basic tone color number is updated to N 'having the same value as N at the start time, and the variation number is changed to M at the start time. Is updated to M ′ of M ± 1, and the process proceeds to step S4. Note that such processing in step S6 is processing in the normal mode. After the processing in step S4 is executed,
The updated basic tone number N 'is returned to N, and the updated variation number M' is returned to M (step S
7), the tone color setting processing routine ends. As described above, according to the electronic musical instrument 1 of the present embodiment, the reference table 131 shown in FIG. 3 defines recommended timbres that the maker wants the customer to listen to at the store or the like for each timbre group. Therefore, by changing the basic tone number using the decrement key 153 or the increment key 154 in the variation number automatic assignment mode, the tone of the recommended tone of each tone group is successively changed according to the change of the basic tone number. Can be generated. Further, each variation number defined in the reference table 131 shown in FIG. 3 can be rewritten to a variation number or a timbre name representing a different timbre in the same timbre group by using a not-shown operator. For this reason, if the user's favorite timbre for each timbre group is defined in the reference table 131 shown in FIG. In accordance with the change of the basic tone color number, it is possible to successively generate musical tones of a tone color desired by the user of each tone color group. Further, in the normal mode, any tone in the tone list shown in FIG. 2 can be set for the sound source 16. The electronic musical instrument 1 of the above-described embodiment is
